Project Title:
Kootenai River Ecosystem Restoration
 
Proposal Short Description:
The primary goal of this project is to recover a productive, healthy and biologically diverse Kootenai River aquatic ecosystem across multiple trophic layers. This work is important to help mitigate the effects of Libby Dam on aquatic processes in downstream river reaches. Currently the project is implementing several nutrient restoration efforts to help mitigate 30 years of lost productivity due to Libby Dam hydro operations.
 
Proposal Executive Summary:
The overarching goal of project 1994-049-00 is to recover a productive, healthy and biologically diverse Kootenai River ecosystem, with emphasis on native fish species rehabilitation. This project is designed to aid the recovery of important fish stocks, such as Kootenai River white sturgeon, burbot, bull trout, kokanee salmon and other fishes important to the Kootenai Tribe of Idaho and regional sport-fisheries.

The primary objective of the project has been to address factors limiting key fish species within an ecosystem perspective. Major project components completed include: establishment of a comprehensive and thorough biomonitoring program, investigation of ecosystem-level productivity, testing the feasibility of a large-scale Kootenai River nutrient addition experiment, the rehabilitation of key Kootenai River spawning and rearing tributaries, the provision of funding for the Canadian government for nutrient enrichment and monitoring in Kootenay Lake, providing written summaries of all research activities, and, holding an annual workshop with other agencies to discuss management, research, and monitoring strategies related to Kootenai River basin activities. Therefore this project, which addresses system productivity and other ecosystem level management issues, is vital to the recovery of the larger Kootenai River ecosystem.

This work is important to restoring ecosystem functions of the Kootenai River lost during the past century. System productivity has been a main focus of this project over the course of the last decade. A major loss of nutrient inputs has occurred due to the construction of Libby Dam and the extensive diking of the river in its lower reaches for agricultural and flood control purposes. These combined perturbations have resulted in a very nutrient poor environment below Libby Dam, especially in the Idaho portion of the Kootenai River, and further downriver in Kootenay Lake, B.C.. Empirically oriented, in-depth, and statistically rigorous biomonitoring by this project has laid the groundwork for characterization of the river as very nutrient poor and in need of supplemental nutrient enrichment.

Starting in 2004 this project began funding experimental nutrient additions to Kootenay Lake, British Columbia through the B.C. Ministry of Environment. The following year (2005) the Kootenai Tribe of Idaho (hereafter the tribe) and the Idaho Department of Fish and Game (IDFG) began an experimental nutrient addition effort in the Kootenai River at the Idaho-Montana border to offset nutrient losses from Libby Dam and downriver wetland depletion. These supplemental efforts have yielded some very positive initial results in Kootenay Lake and the upstream river addition area. Both the lake and river have had significant increases in trophic level productivity, including significant increases in important fish species abundances. These significant gains in productivity have brought the regulated Idaho reaches of the river back to levels likely not seen for 30 or more years. In general, river-ecosystem productivity in Idaho is also now on par with levels observed in the unregulated reaches of the Kootenai River in British Columbia.

In addition to gains in overall ecosystem productivity, nutrient mitigation efforts have had significant and positive effects on numerous and, nearly all metrics measured by the project. Kootenai River positive examples include: No significant increases in ambient water nutrient loads or metals concentrations, significant increases in algal and macroinvertebrate species diversity and biomass, significant increases in desirable and edible types of algae (e.g. diatoms), significant increases in desirable/edible types of macroinvertebrate species (e.g. mayflies). Conversely, no increase in undesirable or potentially detrimental species of native or non-native fishes has occurred, especially species that could prey upon sensitive lifecycle stages of the endangered Kootenai River white sturgeon.

Kootenay Lake positive metrics include: suitable nitrogen to phosphorus ratios for phytoplankton growth, and, a suitable phytoplankton species composition for growth of desirable zooplankton species that in turn benefit kokanee salmon. Since nutrient addition commenced in the South Arm of Kootenay Lake in 2004, a tripling of native kokanee salmon and a doubling of rainbow trout biomass has occurred.

It is important for this work to continue to mitigate for hydro operations and the ongoing loss of sediments, nutrients, particulate organic matter, and the associated productivity and habitat features that come with them. It is also important for this project to continue to explore, evaluate, and implement options to further improve the Kootenai River ecosystem. Additionally, the project will continue to serve as a vehicle to monitor, evaluate, and coordinate with other Sub-basin projects working to improve habitat and other aspects of the Kootenai River ecosystem.

Ecosystem Restoration Project work will be largely be carried out by tribal staff and specialized contractors for selected tasks and work elements. Kootenai Tribal management and staff are responsible for field work operations to include the collection of lower trophic level and water chemistry data. Fisheries community data will be collected cooperatively with the Idaho Department of Fish and Game, and the Montana Fish Wildlife and Parks Department.

Project results will be summarized and presented at an annual meeting of the International Kootenai/y river Ecosystem Restoration Team (IKERT ). This multidisciplinary group is comprised of project managers, scientists, and academics that provide expertise, insight, guidance and adaptive management direction for the project. The project will consult with various specialized contractors to complete project goals and objectives, including fisheries scientists, food web and other modeling experts, technicians, hydrologic engineers, various taxonomic experts, water chemistry laboratories, statisticians, a database management consultant, and other specialist as needed.

All project activities will be carried out within the Kootenai River basin and at the Kootenai Tribal offices based out of Bonners Ferry, Idaho, with the exception of a few project meetings with specialists. Field station facilities of the Idaho Department of Fish and Game, also located in Bonners Ferry, are also available for project work. Project funding provided to the British Columbia Ministry of Forests, Lands and Natural Resource Operations (BCMFLNRO) for Kootenay Lake nutrient restoration work will be administered out of the Nelson, B.C. offices, located on the west arm of Kootenay Lake, and carried out by government and contractor personnel. The Kootenai Tribe of Idaho envisions this ecosystem restoration work to be continuous in nature to repair damage and losses described previously. The tribe especially believes that as long as Libby dam is operational and fisheries remain depressed and dysfunctional, mitigation efforts will be needed.

A large-scale biomonitoring program covering approximately 235 km of the Kootenai River and key tributaries (established since 2002) will be used to monitor the effectiveness of project actions. It is designed to be sensitive to individual and aggregate trophic-level responses including water chemistry, algal, macroinvertebrate, and fish metrics. In addition, the project developed a fine-scale biomonitoring program in 2005, specifically to monitor the effectiveness of the nutrient addition experiment in the Kootenai River. Additionally, this project will also benefit and coordinate with other basin projects managed by the tribe and other agencies.

Project Significance to Regional Programs: View instructions
Kootenai River Ecosystem Restoration Project (KRERP)– Significance to Regional Programs: Northwest Power and Conservation Council’s Columbia River Basin Fish and Wildlife Program: The Kootenai River Ecosystem Restoration Project (KRERP) addresses the vision in the Northwest Power and Conservation Council’s Columbia River Basin Fish and Wildlife Program (FWP) (NWPPC 2000) of “a Columbia River ecosystem that sustains an abundant, productive, and diverse community of fish and wildlife, mitigating across the basin for the adverse effects to fish and wildlife caused by the development and operation of the hydrosystem and providing the benefits from fish and wildlife valued by the people of the region. This ecosystem provides abundant opportunities for tribal trust and treaty right harvest and non-tribal harvest and the conditions that allow for the recovery of the fish and wildlife affected by the operation of the hydrosystem and listed under the Endangered Species Act……. ” The KRERP also addresses the overarching objectives for biological performance to “protect, mitigate, and enhance fish and wildlife of the Columbia River and its tributaries”. In addressing resident fish losses, the FWP states that “the development and operation of the hydrosystem has also resulted in losses of numbers and diversity of native resident fish, such as bull trout, cutthroat trout, kokanee, white sturgeon and other species.” The KRERP addresses the following Basin Level Resident Fish Objectives in the Council’s Fish and Wildlife Program: • Maintain and restore healthy ecosystems and watersheds, which preserve functional links among ecosystem elements to ensure the continued persistence, health and diversity of all species including game fish species, non-game fish species, and other organisms. • Protect and expand habitat and ecosystem functions as the means to significantly increase the abundance, productivity, and life history diversity of resident fish at least to the extent that they have been affected by the development and operation of the hydrosystem. • Achieve population characteristics of these species within 100 years that, while fluctuating due to natural variability, represent on average full mitigation for losses of resident fish. The 2009 amended FWP Program continues to focus on protecting and restoring habitat in order to rebuild healthy, naturally producing fish and wildlife populations. The Council adopted the Kootenai Tribe’s amendment recommendation for the Kootenai Subbasin (in Appendix E) that emphasizes the need to fund and implement a set of integrated measures that protect, mitigate, and enhance fish and wildlife populations, communities, and required habitats and biological and ecological functions that remain affected by construction and operation of Libby Dam and the Columbia River Hydropower system. The KRERP is an integral part of this recommendation. Kootenai River Subbasin Plan prepared for the Northwest Power and Conservation Council (2004): The KRERP contributes to the achievement of the vision for the Kootenai River Subbasin to establish and maintain a healthy ecosystem characterized by healthy, harvestable fish and wildlife populations, normative and/or natural physical and biological conditions, and sustainable human communities. Achievement of the vision is consistent with the scientific principles adopted in the FWP and the guiding principles adopted for Kootenai River Subbasin Plan. The Kootenai River Subbasin Plan provides a comprehensive and detailed array of biological and ecological objectives for fish and wildlife populations and habitats. The Kootenai River Ecosystem Restoration Project addresses the following Urgent and High Priority aquatic biological objectives for Bull Trout (BT), Redband Trout (RBT) Westslope Cutthroat (WCT), Kokanee (KOK), white sturgeon (WST), and Burbot (BUR). Page numbers corresponding to the following objectives by focal species in the Subbasin Plan are listed in parentheses: • Restore productivity and nutrients – BT5 (47), KOK1 (56), BUR1 (65), and WST1 (60) • Restore and maintain population size – BT2 (43), RBT2 (49), WCT2 (53), KOK3 (58), WST3 (63), and BUR4 (70) • Restore natural recruitment – WST2 (62), BUR3 (68) • Rehabilitate native community composition – KOK2 (58), BUR2 (67) • Maintain or increase number of local populations – BT1 (41), RBT1 (48), WCT1 (52). • This project also addresses the following high priority Harvest Objective (HAR1 – page 72) – Maintain or increase harvestable sport fish while protecting native species • and the following Administrative/Programmatic Objectives (AP2 –page 90, AP3 – page 91, and AP5 – page 92) – Develop and maintain adequate regional and international coordination, pursue independent peer-review and qualified scientific counsel, and improve distribution of information required to successfully implement the Subbasin Plan. In: USFWS Biological Opinion for White Sturgeon in the Kootenai River (2006): This project is listed as "necessary and appropriate” (in terms and conditions) to implement the reasonable and prudent measure 1f on page 73 in the Biological Opinion consultation conducted by USFWS Regions 1 and 6 on December 20, 2000. Specifically: 1f. "The action agencies shall seek a means to support an equitable portion of the ongoing Kootenay Lake fertilization program by 2001. This program increases the Lake's productivity and forage base, presumably providing a benefit to sturgeon". In: Multi-Year Implementation Plan (MYIP): The primary objectives of this project are supported by the Multi-Year Implementation Plan (MYIP) objectives because they evaluate “healthy ecosystems which preserve functional links among biota to ensure the continued persistence, health, and diversity of all species including game fish species, nongame fish species, and other organisms” (RFM-CBFWA 1997). In USFWS Biological Opinion: The following text from the Draft USFWS Biological Opinion (Effects to Listed Species for Operations of the Federal Columbia River Power System, July 27, 2000), provides strong rationale for inclusion of Objectives 8 and 9 of this proposal (compensation for total fertilizer acquisition costs for Kootenay Lake and Arrow Reservoir fertilization projects O&M Objectives 1 and 2 in Part 1 of this proposal): • 11.B. Kootenai River Sturgeon 1.i (pg. 74): "The action agencies shall seek opportunities to reduce July/August summer flow through Kootenay Lake. One such opportunity would be retention of water in Lake Koocanusa under a Libby-Arrow water exchange. The objective of this effort is to minimize flushing the eplimnetic forage base from Kootenay Lake during the peak of the growing season, as this food base, in part, supports the sturgeon". • 11.B. Kootenai River Sturgeon 1.j (pg. 74): "The action agencies shall seek a means to support an equitable portion of the ongoing Kootenay and Arrow Lakes fertilization program by 2001. This program will minimize harm to sturgeon through forage base loss". • Draft Biological Opinion (USFWS, July 27, 200) measure 11.B.1.i directly supports inclusion of Objective 1 and 2 of this proposal. Finally, our proposed research goals address mandates from provincial and federal fisheries and environmental management and regulatory agencies in British Columbia, Canada, (a particularly strong working relation has been formed with the British Columbia Ministry of Environment, Nelson B.C. office) where a majority of the Kootenai River Basin is located. Because much of the theoretical and empirical science, and logistical knowledge supporting nutrient enhancement was developed in British Columbia, and because the Kootenai River is an international waterway, our integrated project design provides maximum benefit from international coordination. Kootenai River White Sturgeon Recovery Implementation Plan 2005-2010: The Kootenai River White Sturgeon Recovery Implementation Plan provides background, justification, tasks, and activities for 2005 through 2010 based on strategies identified in the recovery plan and new information that has been developed since the plan was adopted in 1999 (KTOI 2005). This 5-Year Plan has four main components corresponding to the four primary strategies in the recovery plan: (1) Recruitment restoration, (2) Conservation), (3) Monitoring, and (4) Plan adaptation and revision. The schedule identifies core program elements that are annually implemented. The schedule also identifies the progression in implementation of other measures needed to address recovery. “…The Sturgeon Recovery Team provides support for these ecosystem level projects where possible including Ecosystem Restoration.” The KRERP specifically addresses Strategy 3: to Monitoring of key Aquatic Metrics, and, addresses a key limiting factor identified in the plan (Simplified aquatic foodweb from lack of nutrients) by increasing nutrient availability in the ecosystem. USFWS Biological Opinion Regarding the Effects of Libby Dam Operations on Kootenai River White Sturgeon, Bull Trout, and Kootenai Sturgeon Critical Habitat (USFWS 2006 1-9-01-F-0279R and clarified in 2008): The 2006 Biological Opinion regarding the effects of the operation of Libby Dam on Kootenai River white sturgeon listed six reasonable and prudent alternatives (RPAs), which were subsequently consolidated and clarified into five RPAs in 2008 as a result of litigation and a settlement agreement (USFWS 2008). The information below summarizes the events leading up to the 2008 clarification of the BiOp. On February 18, 2006, the USFWS issued the Biological Opinion (BiOp) regarding the effects of the operation of Libby Dam on endangered Kootenai River white sturgeon, Kootenai sturgeon critical habitat, and bull trout. The BiOp reached a jeopardy conclusion for Kootenai sturgeon, an adverse modification conclusion for Kootenai sturgeon critical habitat, and provided a Reasonable and prudent alternative (RPA). The BiOp also reached a non-jeopardy conclusion for bull trout. The 2006 BiOp listed six reasonable and prudent alternatives (RPAs). The KRERP is integral to the implementation of RPA Component 5 – : Kootenai River/Kootenay Lake Productivity, and RPA Component 6 – Monitoring and Reporting. On May 2, 2006, the USFWS was sued over the BiOp by the Center for Biological Diversity. Interveners included the State of Montana, the Kootenai Tribe of Idaho, and the Mountain States Legal Foundation. A notice of intent to include the USACE in the litigation was received in December 2006. On September 2, 2008, a settlement agreement between the parties was reached. The USACE submitted a request from the USFWS to clarify the RPA and on December 2008 the Service issued the clarification of the RPA that incorporated the actions and items from the settlement agreement, including the support of the KRERP. RPA Component 5 is listed below. RPA Component 5: Kootenai River/Kootenay Lake Productivity The productivity of Kootenay Lake and the Kootenai River are important to the growth and health of adult and juvenile Kootenai sturgeon. Implementing actions that enhance that productivity will provide for the success of other life history stages of the sturgeon. Action 5.1. As included in the proposed action, BPA shall continue (through the NPCC Fish and Wildlife Program) to fund the Kootenay Lake Fertilization program to increase the productivity and food supply for Kootenai sturgeon in the Lake. Action 5.2. As included in the proposed action, BPA shall continue (through the NPCC Fish and Wildlife Program) to fund the Kootenai River Fertilization Experiment initiated in 2005 to evaluate potential increases in productivity and food supply for Kootenai sturgeon in the river. Burbot Conservation Strategy (KVRI 2005): In 2005 the managing agencies of the Kootenai River including the USACE, BPA, NOAA, IDFG, KTOI, USFWS, and BCME produced a Kootenai River Burbot Conservation Strategy and a Memorandum of Understanding (KVRI Burbot Committee 2005) to rehabilitate burbot in the Kootenai River of Idaho, British Columbia, and Kootenay Lake. This document was sponsored through the Kootenai Valley Resource Initiative (KVRI), a grass roots community based group. The document outlines the biological needs of burbot, research findings, population status, and limiting factors. It further develops measures to improve habitat, implement conservation culture, address research needs, and implement monitoring and evaluation of mitigation strategies. The KRHRP addresses the habitat improvement objectives in the Burbot Conservation Strategy. Kootenai Tribe of Idaho and Bonneville Environmental Foundation 10 Year Model Watershed Program: Since 2003, the Kootenai Tribe and Bonneville Environmental Foundation have worked together to develop and implement a 10-year Model Watershed Program that addresses watershed-scale ecological function by implementing a plan with prioritized restoration actions based on specific and measurable restoration objectives, and a 10-year monitoring and evaluation plan for several tributaries to the Kootenai River in Idaho. The KRERP has dedicated work elements that have worked with the Bonneville Environmental Foundation efforts to help restore tributary habitat. Columbia River Basin Research Plan (NPCC 2006): The information gained from the implementation and monitoring of the KRERP will contribute over the long term to the monitoring and understanding of some of the focal research themes identified in the plan, including hydrosystem, tributary and mainstem productivity, population structure and diversity, effects of climate change on fish and wildlife, and monitoring and evaluation to provide information with which to evaluate project outcomes relative to project objectives and programmatic standards.” NPCC Monitoring Evaluation Research and Reporting Plan: The KRERP will contribute to the Northwest Power and Conservation Council’s (NPCC) newly developed Monitoring Evaluation Research and Reporting Plan (MERR 2011) by helping to address Council’s fish and wildlife management questions, high level indicators, and Columbia River Fish and Wildlife Program Indicators. Specifically, the KRERP will address key questions in the MERR Plan, such as: “Are Columba River Basin fish and wildlife abundant, diverse, productive, spatially distributed, and sustainable?”, and, “Are Columbia River Basin ecosystems healthy?” by providing high-level indicator information to assess progress. Additionally, the Tribe has contributed to the development of the Columbia River Basin Resident Fish Research, Monitoring, and Evaluation Implementation Strategies coordinated by the Columbia Basin Fish and Wildlife Authority (CBFWA) during 2011 for the six native focal fish species focal species in the Kootenai River (white sturgeon, burbot, bull trout, westslope cutthroat trout, redband trout, and kokanee). Columbia River Basin Food Webs: Developing a Broader Scientific Foundation for Fish and Wildlife Restoration (ISAB 2011-1): The objectives of this report are to provide a fundamental understanding of aquatic food webs in the Columbia River Basin and to illustrate and summarize their influences on native fish restoration efforts. The project sponsor recognizes the importance of the food web perspective and incorporates some of the basic tenants into the planning and implementation of the Kootenai River Ecosystem Restoration Project.

Problem Statement: View instructions

 The problems addressed by this project include large-scale cultural denutrification, the degradation of physical habitat conditions, and the loss of habitat functionality and natural ecological processes in the Kootenai River system.  In terms of nutrient availability and biological production, the Kootenai River, the central component of a large river-floodplain ecosystem, has experienced a series of shifts in productivity during the past 60 years. These changes include changing from moderately nutrient limited (1940’s) to an overabundance of nutrients (1960’s), to an ultraoligotrophic system (extreme nutrient limitation) during the last three decades (Figure 1) (Northcote 1973; Ashley et al. 1999;  Hoyle 2003; Holderman and Hardy 2004). The increased in anthropogenic contributions of nutrients to the upper Kootenay River in British Columbia (B.C.) from municipal and industrial sources during the 1960s and 1970s increased annual phosphorus loading rates to Kootenay Lake from baseline historical levels of just over 100 metric tons in 1949 to a peak at over 6,000 metric tons per year during 1963 (Northcote 1973; Ashley et al. 1999).

Figure 1. Annual phosphorus loading from the Kootenai River to Kootenay Lake (1960-2003). Cultural enrichment lasted until the late 1970s, followed by a rapid shift to phosphorus limitation by 1980. (Note differences in both axes scales between plots). The dotted horizontal line in the plot at right represents historic loading rates represented by 1949 values (Data provided by the B.C. Ministry of Lands, Forests, and Natural Resource Operations).

The  trophic shift to an extremely nutrient poor ecosystem, due mainly to nutrient losses caused by Libby Dam (near the town of Libby, Montana) operations, and  the loss of extensive floodplain and backwater habitats following levee construction along the lower Kootenai River  upstream of Kootenay Lake which disconnected over 20,000 ha of historic floodplains. Collectively, these perturbations eliminated the ecological connectivity and altered biological and ecological processes that were historically supported by an annual, spring runoff related,  nutrient pulse.  Libby Dam continues to alter the timing, duration, and magnitude of downstream river flows. Upstream from the dam, the Libby Reservoir acts as a nutrient and sediment sink, dramatically limiting downstream transport of sediments (> 80% loss of phosphorus, 40% nitrogen), water- and sediment-borne nutrients, fine and coarse organic matter, and large woody debris (Daley et al. 1981; Woods 1982; Snyder and Minshall 2005).

In addition to significant reductions in nutrient loading, sediment loads and their associated, adsorbed nutrient components were also significantly reduced following completion of Libby Dam; post-dam sediment loading rates decreased by up to two orders of magnitude (Figure 2).

image002 

 Figure 2.  Suspended Load Comparing Pre- and Post-Libby Dam Conditions for the Kootenai River near Copeland, ID (USGS Gage 12318500) (Tetratech 2004).

Dam operations continue to alter hydrologic (water supply) and hydraulic (in-channel flow field) conditions in the Kootenai River, resulting in the ongoing reduction and failure of natural functions such as substrate cleansing and sorting. The maximum pre-dam recorded discharge often exceeded 120,000 cubic feet/sec (kcfs), while post-dam discharges of approximately 40,000 kcfs are normal currently  (Figure 3).

 image003

 Figure 3. Mean monthly flow in the Kootenai River at Bonners Ferry, ID., 1929-1999.

 Following these changes, numerous native fish species in the Kootenai River were listed as threatened or endangered.  Imperiled species include white sturgeon, Acipenser transmontanus, (endangered, USFWS 1994), bull trout (Salvelinus confluentus, threatened), burbot (Lota lota, species of special concern (Paragamian et al. 2000). Previous research in the Kootenai River system, including Kootenay Lake, indicated that nutrient limitation was reducing primary and secondary production, which in turn, were likely limiting fish production (Ashley et al. 1999; Snyder and Minshall 1996, 2005).

 Anders et al. (2002) summarized some of pre and post conditions as follows:

“The pre-impoundment Kootenai River hydrograph was characterized by average river discharge peaks of approximately 60,000 m3/sec during the natural high-runoff period in spring and early summer; post-impoundment river discharge (1973-1989) rarely exceeded 20,000 m3/sec. Post-impoundment river discharge during spring and early summer has been reduced by as much as 67%, and has increased during winter by as much as 300% relative to pre-impoundment conditions (Partridge 1983). The pre-development Kootenai River ecosystem included a naturally functional floodplain over 5 km wide along the 128 km of the river immediately upstream from Kootenay Lake. Diking of this section of the river eliminated thousands of hectares of natural floodplain, and the associated productivity, diversity of habitats, and ecosystem functions (Anders and Richards 1996).”

The previously mentioned diking and channelization of the Kootenai river has altered the flow dynamic of the river and no longer allows floodplain interchanges of nutrients, organic materials, and organisms. These changes have reduced biological diversity and productivity (especially in the lower Kootenai River valley) at all levels of the food web. The loss of an interactive floodplain (over 90% of the historical floodplain has been developed or disconnected; Figure 4), along with reduced imports of nutrients from upstream sources is likely the main cause of the very nutrient poor environment in the Idaho reaches of the Kootenai River.

What are the ultimate ecological objectives of your project?

Examples include:

Monitoring the status and trend of the spawner abundance of a salmonid population; Increasing harvest; Restoring or protecting a certain population; or Maintaining species diversity. A Project Objective should provide a biological and/or physical habitat benchmark by which results can be evaluated. Objectives should be stated in terms of desired outcomes, rather than as statements of methods and work elements (tasks). In addition, define the success criteria by which you will determine if you have met your objectives. Later, you will be asked to link these Objectives to Deliverables and Work Elements.
Objectives: View instructions
System-wide Biomonitoring and Evaluation of the Mainstem Kootenai River (OBJ-1)
The Kootenai Tribe of Idaho and Idaho Department of Fish and Game initiated a comprehensive, multi-trophic level and water quality monitoring program in 2000 to investigate the underlying problems of the Kootenai River ecosystem. Since that time, this project has collected important trophic level and water chemistry data under this objective which has helped characterized the river as extremely nutrient poor and to identify adaptive management options to correct the problem. The Tribe and IDFG opted to try a 5 year, large-scale nutrient restoration experiment on the river in 2005 with controlled additions of the limiting nutrient phosphorus to correct nutrient levels and biological productivity. This experiment will require continued monitoring and evaluation to determine if nutrient restoration is successful and provide insights for other potential solutions and adaptive management options.

Restore Ecosystem Productivity (OBJ-2)
This project is designed to address ecosystem level problems within an adaptive management framework. Bottom-up productivity in the regulated mainstem of the Kootenai River was identified as a strong limiting factor to food web development in the river, ultimately resulting in reduced fisheries (KRSA 2004; Holderman and Hardy 2004). In response, The International Kootenai River Ecosystem Team (IKERT) recommended in 2003 to initiate a 5 year experimental large-scale nutrient restoration effort, which began in July of 2005 with additions of liquid phosphorus to the Kootenai River at the Idaho-Montana border. After the initial 5 year period ended in 2009, additions have continued through 2011. In this proposal, the IKERT team, the Tribe and IDFG are recommending the continuation of nutrient additions as a permanent mitigation effort to replace the substantial loss of nutrients (particularly phosphorus) occurring at Libby Dam under current hydro-operations.

Restore Ecosystem Productivity to Kootenay Lake, B.C. (OBJ-3)
The Kootenai Tribe of Idaho began funding provisions to the British Columbia Ministry of Environment in 2003 to fund monitoring and limnological research in the South Arm of Kootenay Lake. Monitoring confirmed suspicion that nutrient levels in the lake where likely limiting food web and fisheries development. Since numerous fish stocks (e.g. white sturgeon, burbot, koknaee and red-band trout) make annual spawning migrations to Idaho streams from Kootenay Lake, and lake nutrient issues are caused in part by Libby Dam hydro-operations, the Kootenai Tribe proposed and was awarded monies to make annual funding provisions to support nutrient additions starting in 2004. Additions have occurred yearly from June through August and are administered and monitored by the British Columbia Government.

Restore Historically Important Kootenai River Tributary Segments for Key Focal Species (OBJ-4)
The Tribe began a multi-year stream habitat/biota survey of lower Kootenai River tributaries (between Bonners Ferry and Porthill, Idaho) in 2000. Similar to efforts in the Kootenai River, an ecosystem-based perspective has been used in development of monitoring plans and restoration work in tributaries. Streams where historical kokanee salmon spawning has occurred were given top priority in the selection of tributaries segments to be restored, as these native salmonids are a keystone species in the Kootenai River. Additionally, other important fish species, such as burbot, bull trout, and redband trout have historically used these streams for spawning and rearing.

The critical stream segments this objective has and will continue to focus on is the area near the confluence of several key tributaries with the Kootenai River on its historic floodplain. These lower-gradient segments contained the majority of the suitable spawning substrates and rearing habitats historically.

Explanation of Recent Financial Performance: View instructions
Recent financial performance of BPA Project 1994-049-00 has not experienced any significant deviation from its contracted amounts (see above). Yearly contract awards have been spent-out completely or nearly so since the last proposal reviews in 2006-07. Cost share contributions are in-line with proposed cost share projections from the last proposal cycle in 2006. A slight cost share increase has occurred with the Canadian Ministry of Environment due to increased nutrient costs since establishment of the cost share in 2004.
Discuss your project's historical financial performance, going back to its inception. Include a brief recap of your project's expenditures by fiscal year. If appropriate discuss this in the context of your project's various phases.
Explanation of Financial History: View instructions
This project has been continuously underway for 17 years, beginning in 1994 and continuing to the present time. The project trajectory has ranged from exploratory/experimental to monitoring and evaluation, to its present form as an implementation and monitoring/evaluation project. Funding levels have increased as the project resolution and work plans evolved over the years (Table 1). Table 1. Shows project funding since inception through 2005. FY 2006 and beyond noted above. FY Account Type Spending* 1995 Expense $175,000 1996 Expense $175,000 1997 Expense $226,600 1998 Expense $250,000 1999 Expense $245,598 2000 Expense $300,000 2001 Expense $272,410 2002 Expense $380,539 2003 Expense $710,268 2004 Expense $953,377 2005 Expense $1,643,840 Workgroup development, modeling and exploratory trophic level monitoring efforts contributed to budget increases during the late 1990’s. Also in this time frame, an Idaho State University based Kootenai River trophic status and productivity PhD-level study was conducted under the guidance of Dr. G. Wayne Minshall. Another request for increased project funding occurred during the early 2000’s to develop a multidisciplinary work group (IKERT; International Kootenai/y Ecosystem Restoration Team). The project simultaneously developed a comprehensive and statistically rigorous biomonitoring program to characterize chemical and biological baseline conditions in the Kootenai River watershed. (See “Database Management” sections of this proposal for more information). Funding levels increased significantly in 2004 as implementation of the adaptive South Arm Kootenay Lake nutrient addition experiment was funded through the project. A substantial increase occurred during 2005 to implement the Kootenai River nutrient addition experiment. These two efforts combined increased project funding by approximately 400%. The largest financial contributing factors are nutrient purchases (approximately 400 tons of nitrogen per year in the south arm of Kootenay Lake) and construction and operation of the 0.25 acre nutrient tank farm (and associated annual nutrient purchases and leasing of the property) near the Idaho-Montana border. Since 2005, the project has been in implementation mode and contract awards have been relatively constant as the project had no major changes in scope or direction.

View full Project Summary report (lists all Contracted Deliverables and Quantitative Metrics)

Discuss your project's contracted deliverable history (from Pisces). If it has a high number of Red deliverables, please explain. Most projects will not have 100% completion of deliverables since most have at least one active ("Issued") or Pending contract. Also discuss your project's history in terms of providing timely Annual Progress Reports (aka Scientific/Technical reports) and Pisces Status Reports. If you think your contracted deliverable performance has been stellar, you can say that too.
Explanation of Performance: View instructions
Project performance as related to contract deliverables has been very good since 2004. The project has a deliverables rate of greater than 90 percent from 2004-2010 for contracted work elements. Some incomplete work elements have been completed in subsequent years or will be completed during or after the current fiscal year (FY12). In addition the project is in the middle of a contracting period (started 6/1/2011) which would contribute to incomplete deliverables in the above summary. Since 2004, the project has produced 29 technical and/or scientific reports documenting various completions or work element summaries (shown below through 05/2011). In addition to the listed reports the project has submitted 8 further technical reports to the BPA web-based reporting center, project personnel are currently completing two final project summary reports (large-scale and fine-scale reports of biological responses to nutrient addition, through 2010) that we expect to be submitted during 2012. These reports will summarize all findings related to the nutrient addition project that is co-managed by the Kootenai Tribe of Idaho and the Idaho Department of Fish and Game. This project has also completed all BPA status reports in a timely manner. Some status reports were a few days late (average of 3 days), often due to the deadline falling on a weekend or holiday. However project management will strive to be more aware of annual and quarterly report deadlines in the next proposal cycle. Overall however we feel the project has adequately reported on project’s activities during the present funding cycle.

  • Please do the following to help the ISRP and Council assess project performance:
  • List important activities and then report results.
  • List each objective and summarize accomplishments and results for each one, including the projects previous objectives. If the objectives were not met, were changed, or dropped, please explain why. For research projects, list hypotheses that have been and will be tested.
  • Whenever possible, describe results in terms of the quantifiable biological and physical habitat objectives of the Fish and Wildlife Program, i.e., benefit to fish and wildlife or to the ecosystems that sustain them. Include summary tables and graphs of key metrics showing trends. Summarize and cite (with links when available) your annual reports, peer reviewed papers, and other technical documents. If another project tracks physical habitat or biological information related to your project’s actions please summarize and expand on, as necessary, the results and evaluation conducted under that project that apply to your project, and cite that project briefly here and fully in the Relationships section below. Research or M&E projects that have existed for a significant period should, besides showing accumulated data, also present statistical analyses and conclusions based on those data. Also, summarize the project’s influence on resource management and other economic or social benefits. Expand as needed in the Adaptive Management section below. The ISRP will use this information in its Retrospective Review of prior year results. If your proposal is for continuation of work, your proposal should focus on updating this section. If yours is an umbrella project, click here for additional instructions. Clearly report the impacts of your project, what you have learned, not just what you did.
All Proposals: View instructions
  • For umbrella projects, the following information should also be included in this section:
  • a. Provide a list of project actions to date. Include background information on the recipients of funding, including organization name and mission, project cost, project title, location and short project summary, and implementation timeline.
  • b. Describe how the restoration actions were selected for implementation, the process and criteria used, and their relative rank. Were these the highest priority actions? If not, please explain why?
  • c. Describe the process to document progress toward meeting the program’s objectives in the implementation of the suite of projects to date. Describe this in terms of landscape-level improvements in limiting factors and response of the focal species.
  • d. Where are project results reported (e.g. Pisces, report repository, database)? Is progress toward program objectives tracked in a database, report, indicator, or other format? Can project data be incorporated into regional databases that may be of interest to other projects?
  • e. Who is responsible for the final reporting and data management?
  • f. Describe problems encountered, lessons learned, and any data collected, that will inform adaptive management or influence program priorities.

This proposal section begins with the following summarized (bulleted) list of major project accomplishments from its inception in 1994 to the present time. Following the General Major Accomplishments section, a more detailed scientifically rigorous section (DETAILED PROJECT ACCOMPLISHMENTS SUB-SECTION) will follow.

To find reports referenced within this section please go to:  

(GENERAL ANNUAL PROJECT ACCOMPLISHMENTS SUB-SECTION 1994-2011)

1994-1999

  • 1994: Project award to Kootenai Tribe of Idaho, Bonners Ferry, Idaho.
  • 1994-1995: Project initiation. Emphasis of agency changed from single species fisheries management projects to an ecosystem level investigation to identify and rectify factors underlying fish population declines in the Kootenai River, Idaho. From its inception, this project has represented a fundamental shift in thinking, from one of viewing fish population declines as the problem to viewing them as symptoms of underlying ecological limitations to be resolved as the goal of the project.
  • 1994-1996: Participated and provided input to trophic status and productivity study, Kootenai River. Contributed to annual and project progress and completion reports, a Ph.D. dissertation, and subsequent peer-reviewed papers (Snyder and Minshall  1996,  2005; Snyder 2001).
  • 1996-1999: Development and use of an Adaptive Environmental Assessment (AEA) model to: 1) identify factors limiting ecosystem productivity and biodiversity, and 2) identify and prioritize ecosystem restoration and management strategies.
  • 1997: Adaptive management conference was held to discuss ideas and generate hypotheses concerning declining fish stocks in the Kootenai River, with an emphasis on white sturgeon recruitment failure and understanding and correcting ecosystem alterations.
  • 1997: Completion of a one year water quality (nutrient and metals) monitoring program on the Kootenai River. Report found low levels of the critical nutrient phosphorus. Detection limits for nitrogen and phosphorus however were too high to determine if supplemental nutrients would be beneficial. Dissolved metals data revealed mostly low concentrations in ranges typically below detection limits, suggesting no significant toxicity exposure issues with heavy metals in the Kootenai River.
  • 1998: Completion of the first season of evaluating biological and population bio-monitoring data for all fish species in the Kootenai River using electrofishing techniques.  Annual fish community monitoring program began.
  • 1998: A Kootenai River Tributary Macroinvertebrate Investigation was initiated. This study included stream biota and habitat surveys of lower Long Canyon, Parker, and Trout Creeks. Metrics suggested that lower reaches of key tributaries were impacted by excessive sediment input due to overgrazing.
  • 1998: As a follow up to the 1997 AEA workshop, a Kootenai River Simulation Model was completed to evaluate sturgeon responses to various flow scenarios (Korman and Walters 1999). Temporal mismatches were revealed between previously suggested limiting factors  and observed  recruitment failure.
  •  1998: Completed a one-year macroinvertebrate investigation in main stem Kootenai River (Richards 1998).  Report found that macroinvertebrate abundance was low. It was recognized that the study lacked rigorous, quantitative methods, and that the one year timeframe was insufficient to adequately characterize the trophic status of the benthic macroinvertebrate community. The study provided a good baseline from which to develop current macroinvertebrate monitoring protocols.
  • 1998: Completed the first year of a multi-year project to survey selected key spawning tributaries of the Kootenai River. Macroinvertebrates and habitat parameters surveyed. Study suggested that grazing impacts negatively affected substrate health and potential use as spawning habitat for key fish species.
  • 1999: Completed a summary of Adaptive Management modeling exercise. A pilot study to evaluate white sturgeon embryo hatching success was conducted in Kootenai River. The study tested whether viable Kootenai River sturgeon embryos would hatch in the river in the absence of sediment deposition and exposure to predation. The study: 1) concluded that eggs suspended in canisters above substrate while factoring out predation had good hatching success, and 2) suggested that poor substrate conditions are likely limiting sturgeon recruitment success. 

2000-2001

  • 2000: Formation of the International Kootenai/y Ecosystem Restoration Team (IKERT) to develop and guide ecosystem restoration of the Kootenai River. This group was initially composed of 15 to 20 multidisciplinary participants, and varies depending on annual topics covered. The IKERT developed the Kootenai River Monitoring Plan covering multiple trophic levels and key water quality parameters. Additionally, a small-scale nutrient addition experiment (mesocosm study) was developed to test the feasibility of a large-scale nutrient experiment in the Kootenai River.
  • 2000:  Development and refinement of Kootenai River Biomonitoring Program.  IKERT group evaluated study designs, sampling regimes, and sample sizes for various trophic levels so that they were biologically sound and had the statistical power to   assess whether future restoration efforts would benefit  Kootenai River biota.
  • 2001: Year one of controlled, replicated, in-river nutrient mesocosm experiment.
  • 2001: Year one of Kootenai River Biomonitoring Program,  collected water quality, algae, macroinvertebrate, and fish community data across the Kootenai River basin.

 (DETAILED PROJECT ACCOMPLISHMENTS SUB-SECTION)

In addition to the list of general annual project accomplishments provided above, many additional specific project accomplishments have occurred since experimental nutrient addition began (2004 in Kootenay Lake’s South Arm, 2005 in the Kootenai River). Notable accomplishments include a consistent and diverse array of ongoing positive, statistically significant biological responses across trophic levels of the food-web and a wide range of associated metrics.  Benefits were measured against pre-treatment and untreated conditions at both large and fine spatial scales in the Kootenai River and in Kootenay Lake. 

A detailed summary of specific project accomplishments is presented below, organized by ascending trophic level, each within three sections: 1) large scale, spatial and temporal responses to nutrient treatments in the river; 2) fine-scale, spatial and temporal, responses to nutrient treatments in the river, and 3) biological and chemical responses to nutrient treatments in Kootenay Lake.  By design, the fine-scale monitoring project was geographically nested within the large-scale biomonitoring program to evaluate treatment effects with higher spatial and temporal resolution (Figure 1).  Project monitoring at Kootenay Lake, on the other hand, was designed to measure effects of nutrient addition in the South Arm of Kootenay Lake.

For each section, we briefly describe notable project accomplishments, including development and implementation of specific project objectives, associated hypotheses and analyses, sampling regimes and project results. We also briefly discuss the biological relevance of the critical findings. In the following sections, we also refer the scientific reviewers and other interested parties to appropriate online project reports and papers for more detailed information and analytical results for the topics at hand.

1) Kootenai River large-scale project accomplishments

Project accomplishments are provided below in the order of ascending trophic level regarding objectives, hypotheses and analyses, sampling regime, sampling techniques, and results.

 Objectives – The following project objectives addressed desirable biological conditions over a 325 km reach of the Kootenai River in Idaho, Montana, and British Columbia from 2003-2010. These objectives, organized by ascending trophic level, include the following:

 Water Quality Metrics

  • Improve unsuitable water quality parameter values
  • Do not increase any dissolved metal concentrations associated with the inorganic nutrient source being added (ammonium polyphosphate 10:34:0)

Nutrient  Metrics

  • Increase in-river concentrations of various nutrient (Nitrogen (N) and Phosphorus (P)) forms
  • Maintain or improve in-river nutrient balance (reflected by N:P ratio values)
  • Reduce the degree of P limitation (shift N:P ratio values closer to 20:1)
  • Avoid inducing Nitrogen Limitation

Periphyton Community Metrics

  • Increase abundance and biomass of edible taxa (diatoms, green algae)
  • Decrease or stabilize abundance and biomass of inedible/toxic taxa  bluegreen algae (Cyanobacteria)
  • ?

Benthic Macroinvertebrates  Metrics

  • Increase the abundance, biomass, and diversity of edible taxa

Fish  Metrics

  • Increase the abundance, biomass, biological condition factor, and growth of native and sport-fish species
  • Do not negatively affect fish community composition

 Hypotheses and Analysis – This project also generated and tested the following null hypotheses to assess effects of nutrient addition, organized by ascending trophic level. For the purposes of statistical analysis, treatment periods were defined as: a pre-treatment period from 2003 through June, 2005 and a post-treatment period from July, 2005 to 2010.  These hypotheses are followed by a brief description of associated statistical analyses.

Nutrient Metric Hypotheses:

  • Nitrite + nitrate (NO2 + NO3) concentrations were not significantly different following nutrient addition.
  • Total nitrogen (TN) concentrations were not significantly different following nutrient addition.
  • Ammonia (NH4) concentrations were not significantly different following nutrient addition.
  • Soluble reactive phosphorus (SRP) concentrations were not significantly different following nutrient addition.
  • Total dissolved phosphorus (TDP) concentrations were not significantly different following nutrient addition.
  • Total phosphorus (TP) concentrations were not significantly different following nutrient addition.
  • Total nitrogen/total phosphorus (TN/TP) ratio values were not significantly different following nutrient addition.
  • Dissolved organic nitrogen: Total dissolved phosphorus (DIN/TDP) ratio values were not significantly different following nutrient addition.

 Nutrient Analyses - ANOVA procedures were used to test the above nutrient hypotheses utilizing seasonal averages. Statistical significance for all comparisons was assessed at the a = .05 level. Data were log-transformed when necessary to meet the assumptions of statistical analysis.  All statistical computations for water quality responses were carried out using SAS 9.2 (SAS 2009).

 Periphyton and Chlorophyll Metric hypotheses:

  • Community composition (relative abundance) of the soft-bodied algal community was not significantly different following nutrient addition.
  • Total chlorophyll a biomass following nutrient addition was not significantly different.
  • Total chlorophyll a accrual rate following nutrient addition was not significantly different.

Periphyton Analyses - Contingency tables and associated Chi-square (X2) tests on seasonal average abundances were used to assess soft-bodied algal community composition before and after nutrient addition. ANOVA procedures were used to test the chlorophyll hypotheses.  Data were log-transformed when necessary to meet the assumptions of statistical analysis. Statistical significance for all comparisons was performed at the a = 0.05 level. All statistical computations for periphyton and chlorophyll metrics and responses were carried out using SAS 9.2 (SAS 2009).

 Benthic Macroinvertebrate Metric Hypotheses:

  • Overall invertebrate abundance was not significantly different following nutrient addition.
  • Overall invertebrate biomass was not significantly different following nutrient addition.
  • Overall invertebrate richness was not significantly different following nutrient addition.
  • Ephemeroptera (E) Plecoptera (P) and Tricoptera (T) species abundance was not significantly different following nutrient addition.
  • EPT species biomass was not significantly different following nutrient addition.
  • EPT species richness was not significantly different following nutrient addition.
  • Community composition (relative abundance) of EPT species was not significantly different following nutrient addition.

Benthic Macroinvertebrate Analyses - ANOVA procedures were used on seasonal average responses to test the first six invertebrate hypotheses. These data were log-transformed to meet assumptions of statistical analysis when necessary. Contingency tables and associated X2 test were used to evaluate the seventh macroinvertebrate hypothesis. All statistical tests were carried out at a = .05 level. All statistical computations for macroinvertebrate metrics and responses were performed using SAS 9.2 (SAS 2009).

Fish Metric Hypotheses:

  • Overall (all species) fish abundance was not significantly different following nutrient addition.
  • Overall fish biomass was not significantly different following nutrient addition.
  • Biological condition factor (Fulton’s K) for individual species was not significantly different following nutrient addition.
  • Relative weight (Wr) for individual species was not significantly different following nutrient addition.
  • Fish community composition (relative abundance by species) was not significantly different following nutrient addition.
  • Relative abundance of fish age composition (as measured by mean length at age for mountain whitefish (MWF) were not significantly different following nutrient addition.

Fish Analyses ANOVA procedures were used to test for effects of nutrient addition on fish abundance, biomass, and biological condition (K) (first three hypotheses). Contingency tables and associated Chi-square (X2) tests were used to assess community composition before and after nutrient addition. All statistical tests were conducted, at the a = 0.05 significance level. A nonlinear regression mixture model was developed and used to assess mean length at age for MWF before and after nutrient addition using data from 2002-2008 (Shafii et al. 2010) and subsequently validated using analogous data collected during 2009 and 2010.  A specific description of this model follows:

Mountain whitefish length and age response - A three-component mixture model based on normal variates was employed to describe the MWF length at age distribution before and after nutrient addition. The resulting model provided parameter estimates with meaningful biological interpretations, which were used for inferential and comparative purposes. The mixture modeling technique provided a means to explore potential sub-population structure in the data.  The general form of the mixture model was given by:

yij =  pf1(xi) + pf2(xi) + … + pfm(xi) + eij =  ∑km pfk (xi)  +  eij             (1)

where yij is the jth replication of the proportion of fish at the ith length, xi , and eij, is an error term assumed eij~NID(0, s2).  The terms f1(xi) through fm(xi) are functional forms for the m sub-populations or components.    Here, the fk(xi) was specified by a two parameter normal distribution as:

fk(xi)  = N(mk, sk2)  =  (1/Ö2psk) exp(-(xi - mk)2/2sk2)                            (2) 

the above normal density function provided meaningful biological interpretations. In this case, the component parameters, mk and sk, had relevant interpretation, representing the average length and variability of each sub-population, respectively.  Sub-populations entered the model with proportions p1 through pm, respectively, with the constraint:

pk = 1.0.

Model estimation was carried out using nonlinear regression with a maximum likelihood algorithm (normal likelihood assumed), with an expected value given by equations (1) and (2), and a constant variance, σ2.  Separate estimation was used for data from the pre- and post-treatment time periods.  Following estimation, fish distribution parameters were compared across management conditions using dummy variable techniques. All statistical computations for fish metrics were carried out using SAS 9.2 (SAS 2009).

Sampling regime – This project designed, implemented, and refined a comprehensive multi-metric and multi-trophic monitoring and evaluation program to provide data from up to 13 standard sites in the Kootenai River in Idaho, Montana, and British Columbia (Figure 1).  Sampling reaches intentionally included an unimpounded reach above Libby Dam and four reaches downstream from Libby Dam affected by impoundment: two in the canyon reach (one with and one without nutrient addition), a braided reach, and a meandering reach (Table 1). This design allowed project proponents to simultaneously and sequentially statistically test for impoundment, treatment, reach, and temporal effects to evaluate experimental nutrient addition in the Kootenai River. For more details concerning large-scale project sampling techniques, equipment, intensity, and frequency, please refer to the appropriate proposal section(s) that detail sampling, and recent reports on water quality (Holderman et al. 2010a), periphyton and primary production (Holderman et al. 2009b), benthic macroinvertebrates (Holderman et al. 2009a), and fish (Holderman et al 2010b), and KTOI (2011) for all trophic levels from 2003-2010 except fish.

Large-scale Project Monitoring Results

Nutrient response synopsis – The success of the initial period of experimental nutrient addition (2005-2010) was confirmed by: 1) achieving the project’s three water quality and four nutrient objectives, and 2) rejection of six of the project’s eight nutrient null hypotheses that assumed no significant nutrient treatment effects. Although the project performed many analyses of nutrients with many spatial and temporal comparisons (Holderman et al. 2010a; KTOI 2001), the following sections are focused solely on the nutrient addition zone sites (KR6, KR9, and KR9.1), where the largest responses occurred, along with the upstream impounded reference site (KR10) to account for hydro operations without nutrient addition, and the unimpounded upstream reference site (KR14) in British Columbia, upstream from Libby Dam and Lake Koocanusa to account for conditions controlling for  impoundment and nutrient addition effects. 

Mean concentrations of nutrients (Nitrate+Nitrite, TN, TDP, and SRP) increased significantly following nutrient addition (Figures 2 and 3), while TN:TP ratio values decreased significantly to < 30:1, indicating a significant reduction in P limitation in the Kootenai River following nutrient addition (data not shown). While significant treatment effects were observed following nutrient addition in the treated areas, some variable values also responded significantly at upstream reference sites due to non-treatment effects (e.g. environmental variability, stochasticity, and dam operations). However, compared to responses in reference reaches, treatment responses (in treated areas) were typically significantly higher or greater in magnitude, and consistent with the direction of treatment responses following nutrient addition.

Figure 3. Log total dissolved phosphorus (TDP) values (milligrams per liter; μg/L) before and after nutrient addition in the Kootenai River nutrient addition zone (KR6, KR9, KR9.1) and at the upstream impounded (KR10) and un-impounded (KR14) reference sites.

Ammonia and SRP were the only two nutrient metrics that did not show significant, positive treatment effects. In terms of in-river nitrogen responses, both NO2+NO3 and TN increased significantly following treatment. However, in the case of NO2+NO3, no increase in concentration was observed at the unimpounded upstream reference site (KR14). Alternatively, NO2+NO3 increased significantly at the hydro-affected reference site (KR10) approximately 18 km upstream from the nutrient addition site. This suggested that the increased concentration of NO2+NO3 at KR10 during treatment years resulted from some combination of Libby Dam operations and vertical distribution of withdrawal and vertical NO2+NO3 distribution in the forebay (immediately upstream from the dam), rather than from increased ambient abundance upstream in the unimpounded river. Thus, increased nutrient concentrations in the nutrient addition zone may have been bolstered to some degree by these increased ambient TN concentrations during post-treatment years.  However, the consistently larger magnitudes of nitrogen metric responses in the nutrient addition zone following treatment contributed to the significant treatment responses for most nitrogen forms.

In terms of in-river phosphorus responses, all measured phosphorus forms showed significant, positive treatment effects except SRP. As seen with the nitrogen responses, TDP and TP concentrations did not increase at the unimpounded upstream reference site (KR14), but did increase slightly at the hydro-affected reference site (KR10). This seems to preclude any confounding effects of increased ambient phosphorus on significant increases in the nutrient addition zone following treatment. Alternatively, SRP values decreased at both upstream reference sites from pre- to post-treatment years, yet SRP increased in the nutrient addition zone, although not significantly. This biologically but not statistically significant finding is not surprising because SRP represents the biologically available form of phosphorous in rivers, which is more subject to increased biological demand than other forms. Thus, in-river SRP concentrations can be quickly reduced by increased biological uptake by primary producers.

Periphyton (Primary Producers) response synopsis – Success of this initial period of experimental nutrient addition (2005-2010) was confirmed by: 1) achievement of the project’s two periphyton objectives, and 2) rejection of the project’s periphyton response null hypotheses that assumed no significant treatment effects.

Periphyton community composition changed significantly, with edible diatoms (Bacillariophyta) and green algae (Chlorophyta) increasing significantly in
abundance and biomass and inedible blue green algae (Cyanophyta) significantly decreasing (Figure 4).

image004

Figure 4. Relative abundance (%) of algal taxa for KR6, KR9, KR9.1 (treatment) and KR10 (control) during pre- and post-treatment periods.

Although relative abundance of diatoms varied slightly among sites and years, their consistent dominance in the periphyton community both before and after nutrient addition (80-99% dominance among sites and years), indicated favorable trophic conditions in the Kootenai River.

These trends are all ecologically desirable, as diatoms are typically a major source of primary production in aquatic systems (Stevenson et al. 1996; Lamberti et al. 2007), and both diatoms and green algae provide important food sources for benthic macroinvertebrates and other primary and secondary invertebrate and vertebrate consumers (Pekarsky 2007). In addition, the consistent reduction in relative abundance of bluegreen algae at all sites following nutrient addition further reflected positive experimental outcomes. Hence, all three desirable outcomes of nutrient addition as reflected by periphyton metrics were observed: relative abundance of edible diatoms and green algae increased, and relative abundance of inedible bluegreen algae decreased.

For more details regarding the study area, methods, data, analyses, results, and discussion regarding periphyton and periphyton responses, please refer to Holderman et al. (2009b) and KTOI (2011).

 Chlorophyll (primary production) response synopsis – Success of this initial period of experimental nutrient addition (2005-2010) was confirmed by: 1) achievement of the project’s chlorophyll objective, and 2) rejection of the project’s two chlorophyll response null hypotheses that assumed no significant treatment effects.

Chlorophyll a and total (chlorophyll a and b) biomass and accrual rates increased significantly following nutrient addition (P < 0.0001 for all comparisons)(Figure 5).

A significant positive total chlorophyll biomass and accrual responses to nutrient addition were observed (Holderman et al. 2009b, Hoyle et al. 2011; KTOI 2011) following nutrient addition. As observed with other trophic level metric responses, the magnitude of chlorophyll metric responses increased in magnitude as a function of proximity to the nutrient addition site. This longitudinal gradient indicated lower nutrient uptake due to reduced availability at sites progressively downstream from the point of nutrient addition. The lack of response by both chlorophyll metrics at both reference sites further validated the positive treatment responses observed in the nutrient addition zone, and confirmed the suitability, as reference sites, of the upstream hydro-affected and unimpounded reference locations.

Invertebrate response synopsis - The success of this initial period of experimental nutrient addition (2005-2010) was confirmed by: 1) achievement of the project’s invertebrate objectives, and 2) rejection of all seven invertebrate null hypotheses involving abundance, biomass, and community composition that assumed no significant treatment effects.

The overall aquatic insect (all taxa), and the mayfly, stonefly, and caddisfly (EPT), abundance, biomass, and richness increased significantly (P<0.0001 for all comparisons), often doubling or tripling in value following nutrient addition (Figures 6-12).

 EPT abundance, biomass, and richness (ANOVA) - Following nutrient addition: 1) EPT abundance increased significantly at the nutrient addition sites, with a marginally significant increase at the control site, KR10 (p=0.06); 2) EPT biomass increased significantly at nutrient addition sites only; and 3) EPT richness increased significantly for the entire nutrient addition zone (Figures 13 and 14).

Overall (all taxa) richness, as well as aggregated and separate EPT abundance, biomass, and richness showed significant increases following treatment. In most cases, aggregated and separate EPT responses increased during successive treatment years, and almost always were highest during 2009 (the latest invertebrate data available at reporting time). This pattern suggested multi-year additive or cumulative responses among these taxa. Similar, significant responses were also seen among three of the four invertebrate feeding guilds (gatherers, predators, and scrapers), and for in addition to Chironomid richness. Thus, all invertebrate metric responses to nutrient addition were consistently and positive and strongest near the nutrient addition site.

Fish response synopsis - The success of this initial period of experimental nutrient addition (2005-2010) was confirmed by: 1) achievement of the project’s fish objectives, and 2) rejection of five of the six null hypotheses involving fish abundance, biomass, biological condition (K), relative weight (Wr), and community composition that assumed no significant treatment effects.  A total of 17 fish species were caught, with six dominant species accounted for > 98% of the catch data, and the single most dominant species, whitefish (MWF) accounting for over 60% of the overall catch.  These six dominant species included: MWF, large scale suckers (LSS), northern pikeminnow (NPM), rainbow trout (RBT) redside shiner (RSS) and peamouth chub (PMC).  Overall abundance, biomass, and biological condition increased significantly following nutrient addition, for several dominant native fish species, as did the mean length at age for mountain whitefish from one to three years old. The only fish objective that was not rejected (Wr) may have been due to failure of nutrient addition to significantly change relative weight for three dominant species for which standards were available in the literature. An insignificant treatment effect for this metric may have been affected by allometric fish growth, age-specific variation in length at age relationships among species, and differences in the age distributions of samples before and after treatment.

For all reported fish analyses, 2003 through 2005 were considered pre-treatment years while post-treatment years occurred from 2006 through 2010.  Treatment effects on fish responses during the four month period in 2005 prior to fish sampling were considered to be negligible.  Hence, data from 2005 were designated as pre-treatment.  ANOVA revealed significant increases for abundance, biomass, and biological condition for mountain whitefish (MWF), rainbow trout (RBT), and large-scale suckers (LSS) following nutrient addition (Figures 15-23).

However, relative weight (Wr) for these same three species was variable. Although LSS showed an increase in Wr, MWF showed a decrease at sites KR6 and KR9 and an increase at KR10, and RBT indicated little change in Wr except at KR14, the upstream unimpounded reference site in BC, where a decrease in RBT Wr was observed (Figures 24-26).

 Fish Community Composition Response

Abundance:  The association between fish community relative abundances in the Pre and Post nutrient addition treatment periods for the six dominant fish species was tested separately for each of the nutrient addition zone NAZ, defined as Sites KR6, KR9 = NAZ), KR10, and KR14. A significant shift in relative abundance among the six dominant fish species occurred in the NAZ (p=0.025), KR10 (p=0.025), and KR14 (p<0.0001; Table 2). Responses were largely driven by an increase in LSS and a decrease in MWF at KR14, increases in MWF and RBT at KR10, and an increase in MWF in the NAZ (Table 2).

Figures 27 and 28, below, portray changes in the fish community described above by Chi square analysis.

  • The relative abundance of MWF increased substantially in the NAZ (69 to 78%), while it decreased in KR14 (65 to 50%).  Relative abundance at KR10 remained relatively unchanged. 
  • Species LSS decreased slightly at KR10 and in the NAZ, while an increase of 10% was seen at site KR14.
  • The relative abundance of RBT increased substantially at KR10 and slightly at KR14, with a slight decrease seen in the NAZ.
  • Catch per hour indicated relatively little treatment effect on dominant species at KR2 and KR4.  Sites KR6 and KR9 showed large increases in MWF numbers and moderate increases in RBT and LSS.  Post-treatment values at KR9.1 followed these trends at a larger scale.  Site KR10 had a smaller increase in MWF and RBT numbers.  At KR14, (the upriver, unimpounded reference site), LSS abundance increased markedly, while MWF decreased slightly and RBT values remained unchanged.

Two ecologically and recreationally important native fish species (MWF and RBT) mountain whitefish and rainbow trout that increased significantly abundance in the NAZ also displayed the largest abundance increases at KR9.1. Although fish sampling at KR9.1 began in 2009, large post-treatment increases prior to that occurred at the next adjacent site downstream (KR9), revealing a positive treatment effect (Figures 29 and 30).

Biomass - Biomass per hour trends were similar to those of abundance.  It was notable, however, that MWF had a nearly 2-fold increase in abundance and biomass at KR9 (closest to the nutrient addition site) during the post-treatment period.

Similar positive post-treatment responses and longitudinal response gradients were seen by these species in terms of biomass, with highest values at the nutrient addition site, flowed by decreasing values in a downstream direction (Figures 31 and 32 ).

Overall catch data, trends, for all species – A total of 17 fish species were recorded during the study over all sites and years (Table 3). Of these 17 species, six dominant species accounted for > 98% of the catch data, with the single most dominant species, whitefish (MWF) accounting for over 60% of the overall catch (Table 3).  The six dominant species included: MWF, large scale suckers (LSS), northern pikeminnow (NPM), rainbow trout (RBT) redside shiner (RSS) and peamouth chub (PMC). 

Other notable results included:

  • MWF and RBT showed steady increase in numbers in the post treatment period (2006 - 2010).
  • LSS also increased during this time, but peaked in 2009.
  • NPM initially peaked in 2006, but has since declined in the post treatment period.
  • RSS also peaked and declined following treatment, but may be recovering.
  • PMC is relatively unaffected in the post treatment period.
  • Several rare species in the catch data (BLT, SCU, BRT, LND, and BUR) may have initially peaked in 2007 following treatment, but have subsequently declined.  This may also be true for species YP and PS, as well.

 Mountain whitefish length at age response – A subsample of MWF fish samples were aged each year within the nutrient addition zone.  Based on these data, a tri-modal empirical distribution of the MWF length at age data was developed for three age classes: 0, 1-2, and 3+ years, respectively (Figure 33). A similar tri-modal distribution in MWF length was observed for the complete un-aged fish data.  Assuming, then, that these modes or subpopulations in the full data set corresponded to the three MWF age classes, a three component mixture model outlined in the hypotheses section above, eq. (1), was estimated separately for the pre-treatment and post-treatment periods (Shafii et al. 2010)  (Figure 33).  Following estimation and assessment of each model, a dummy variable regression technique was used to compare the two models and test for differences in their respective age class mean and variance parameters.

 

image034 

Figure 33 . Mountain whitefish length distribution in the aged fish data.  Three age related sub-populations are indicated (from Shafii et al. 2010).

Results for the specified contrasts (mean length at age before and after nutrient for the three age classes) are shown in Table 4 and Figure 34 below. Treatment differences in relative proportions for age classes 0 and 1-2 years were non-significant, indicating the relative abundances of each age class were unchanged after nutrient addition. Differences in mean, however, were significant for age classes 0 and 1-2.  The older fish, class 3+, showed no change in average length Significant decreases in the variability of length were observed for age classes 1-2 and 3+ years, implying that those fish became more consistent in length following the nutrient addition treatments. Changes in younger fish, age class 0, were non-significant in this regard.

Model validation with 2009 and 2010 data –The post-treatment model shown above was validated using recent (2009, 2010) MWF length data. The 2009 and 2010 data displayed a similar pattern of age classes, and all three age classes followed the estimated model well (Figure 35).

 

 image037

Figure 35. Estimated mixture models for mountain whitefish length distributions prior to (a) and post (b) nutrient addition (from Shafii et al. 2010).

Validation residuals for all age classes were small in magnitude and fairly random looking in nature. In comparison to model fit residuals, the validation residuals showed strong overlap and similar patterns and magnitudes. Juvenile fish (100-150 mm) fit the model well, while older fish (>250 mm) displayed some over prediction at longer lengths. Mid-range fish (150-220 mm) had a shifted distribution towards shorter lengths, relative to the predicted model. Numerically, the validation residual mean was non-significant.  Overall, the distribution of the residuals was symmetric, bell shaped, and centered on zero.

Fish length distributions from individual years showed considerable variability.  This may have been due to unobserved external forces affecting data measurements such as temporal variability in environmental conditions, immigration or emigration patterns, tributary effects, etc.  For these reasons, the combined set of validation data from 2009 and 2010 provided a better overall measure of model performance than individual years. In order to address ongoing sources of such variability, continuation of the validation process with the addition of future measurements is warranted.

In conclusion, use of 2009 and 2010 length at age date confirmed previously reported trends, supporting that nutrient addition significantly increased mean length at age (a proxy for growth) for Age 0, and Age1-2 MWF. Furthermore, use of this mixture model approach provided a novel and statistically rigorous approach to assess effects of nutrient addition on length at age, as a proxy for growth in MWF, an environmentally sensitive, native indicator species in the Kootenai River.

Additional Native Fish Responses from this Project’s Actions 

 In addition to the above biological and population metric responses and trends for fish, native kokanee salmon and white sturgeon responses to nutrient addition were also evaluated by other Tribal projects following nutrient addition.

Kokanee salmon – Dramatic increases in kokanee survival and production in lower Kootenai River tributaries in Idaho were observed following nutrient addition (Figure 36; Anders et al. 2007; Ericksen et al. 2009; KTOI unpublished data).  Low Kootenay Lake productivity and food availability since the middle 1980s reportedly contributed failure of life cycle completion for kokanee (Ashley and Thompson 2003). Beginning in 1991 for the North Arm and 2004 for the South Arm, fertilization efforts were made to Kootenay Lake.  Following the fertilization of Kootenay Lake, trophic level responses for kokanee were significant and positive (Ashley and Thompson 1993; Schindler et al. 2007, 2011) See the subsequent Section 3, Kootenay Lake Project Accomplishments, for more details.    

Although these recent kokanee population responses are encouraging relative to previous decades, the magnitude of recent increases in spawner escapement remains far short of estimates available from the early 1980s, indicating insufficient ecological mitigation at this time. Low escapement numbers in 2009 and 2010 were likely due to low numbers or poor success of previous eyed-egg plants.

White sturgeon - Since 2005, inadequate numbers of juvenile sturgeon have been recaptured to statistically compare growth, survival, and condition prior to and post nutrient addition. However, data are currently being collected and will be analyzed subsequently to address this issue. Meanwhile, it is believed that juvenile white sturgeon will benefit from the suite of significant post-treatment increases seen thus far in the lower trophic responses such as nutrient availability, edible diatom and green algae biomass, chlorophyll biomass and accrual rates, macroinvertebrate abundance, biomass, and richness, consistent with significantly increased abundance, biomass, and condition factor for other fish species.

Nutrient addition began in the South Arm of Kootenay Lake in 2004 and in the Kootenai River during 2005. Stocked kokanee (Meadow Creek B.C. stock) in Idaho waters spawn at three years of age (Data from KTOI).

 2) Kootenai River fine-scale project accomplishments

Sampling regime - Twelve sites were initially designed and sampled, including treatment sites every 1 km.  However, following a sample size evaluation, the decision was made to reduce the sampling effort to eight fine-scale biomonitoring sites beginning in 2007. (Figure 37)   These sites included untreated (control) sites located 11 and 1 rkm upstream from the dosing site, and one site every 2 rkm, starting at one rkm below the dosing site, KRF2.  This adaptive management approach reduced the number of treated sites by 50% without losing significant statistical power or representation.

Objectives – To be consistent with the large-scale project efforts described above, this fine-scale component addressed a number of large-scale project objectives that are designed to achieve improved future biological conditions. These objectives, along with their corresponding hypotheses, were used to evaluate the success of Kootenai River nutrient addition. Unlike the previously discussed large scale monitoring efforts, however, invertebrates and fish were not sampled as part of this fine-scale component of the project.

Specific fine-scale project objectives, organized by ascending trophic level, include:

Water Quality Metrics

  • Maintain suitable water quality parameter values
  • Improve unsuitable water quality parameter values
  • Do not increase any dissolved metal concentrations associated with the inorganic nutrient source being added (ammonium polyphosphate 10:34:0)

Nutrients Metrics

  • Increase in-river concentrations of various nutrient (N and P) forms
  • Maintain or improve the nutrient balance (reflected by N:P ratio values)
  • Reduce the degree of P limitation (shift N:P ratio values closer to 20:1)
  • Avoid causing N-limitation

Periphyton Community Metrics

  • Increase abundance and biomass of edible taxa (diatoms, green algae)
  • Decrease or stabilize abundance and biomass of inedible/toxic taxa  bluegreen algae (Cyanobacteria)

Primary Production

  • Increase total chlorophyll accrual rate (primary production rate)

Hypotheses and analyses - This project also generated and tested the following hypotheses to assess nutrient addition, organized by ascending trophic level. Hypotheses are followed by a brief description of the associated statistical analyses.

Nutrient Hypotheses:

  • Nitrite + nitrate (NO2 + NO3) concentrations were not significantly different following nutrient addition.
  • Ammonia (NH4) concentrations were not significantly different following nutrient addition.
  • Soluble reactive phosphorus (SRP) concentrations were not significantly different following nutrient addition.
  • Total dissolved phosphorus (TDP) concentrations were not significantly different following nutrient addition.
  • Total phosphorus (TP) concentrations were not significantly different following nutrient addition.
  • Total nitrogen/total phosphorus (TN/TP) ratio values were not significantly different following nutrient addition.
  • Dissolved organic nitrogen: Total dissolved phosphorus (DIN/TDP) ratio values were not significantly different following nutrient addition.

Nutrient analyses - ANOVA procedures were used to test the above nutrient hypotheses. Statistical significance for all comparisons was assessed at the a = .05 level. Data were log-transformed to meet assumptions of statistical analysis when necessary. All statistical computations for Water quality and nutrient responses were carried out using SAS 9.2 (SAS 2009).

Periphyton and Chlorophyll Hypotheses:

  • Community composition (relative abundance) of the soft-bodied algal community was not significantly different following nutrient addition.
  • Total chlorophyll accrual rate following nutrient addition was not significantly different.

Periphyton analyses - Contingency tables and associated Chi-square (X2) tests were used to assess soft-bodied algal community composition with and without nutrient addition. ANOVA procedures were used to test the above chlorophyll hypotheses. Statistical significance for all comparisons was performed at the a = 0.05 level. Data were log-transformed to meet the assumptions of the respective analyses when necessary.  All statistical computations for periphyton and chlorophyll responses were carried out using SAS 9.2 (SAS 2009).

 Fine-scale (Temperal and Spatial) Nutrient Monitoring Results

Fine-scale Project Synopsis – Success of this initial period of experimental nutrient addition (2005-2010) was confirmed by: 1) achievement of all ten of the fine-scale project’s water quality, nutrient, periphyton, and chlorophyll (primary production) objectives, and 2) and rejection of all nine associated null hypotheses that assumed no significant treatment effect. 

This project, as measured by the fine-scale water chemistry, chlorophyll, and periphyton metrics described above, maintained desirable N:P ratios, while partially compensating for cultural de-nutrification. Increased chlorophyll production at sites receiving nutrient addition and a favorable relationship between nutrient addition and algal taxonomic composition were also observed.  Algal taxonomic composition analyses revealed increased diatom production and suppressed blue-green algal abundance at treated sites.  Overall, the fine-scale, multi-trophic responses confirmed nutrient addition as beneficial to ecosystem restoration for the Kootenai River in Idaho.  

Water Chemistry - Significant differences in mean NO3+NO2, and TN:TP and DIN:TDP ratio values were observed between treatment (sites below the injection site, KRF2) and reference sites (KRF0 and KRF1)  in all years. Alternatively, no significant differences in TDP concentration were observed in any year except 2009. 

Several spatial (longitudinal) trends were also revealed by analysis:

  • Treated sites typically showed lower NO3+NO2 concentrations than reference sites.
  • Treated sites showed elevated TDP concentrations compared to reference sites.
  • Treated sites showed lower TN:TP and DIN:TDP ratios compared to reference sites, with a stronger treatment effect seen with TN:TP ratios (Figure 38).

Total chlorophyll accrual – Total chlorophyll accrual rate was significantly different between treatment and reference sites in all years showing increased levels following treatment (Figure 39).

 Periphyton Taxonomy - Four periphyton taxa groups were defined: Bacillariophyta (diatom), Chlorophyta (green), Cyanobacteria (blue-green), and “Other”.  Treated sites had significantly higher diatom numbers compared to the reference sites (p< 0.05).  Blue-green algae numbers were higher in the reference sites. Green algae numbers were low in both the treatment and reference sites, but slightly elevated at the treated sites (Figure 40).

3) Kootenay Lake (South Arm) Nutrient Addition Project Accomplishments

(The following section will cover nutrient addition efforts for the South Arm of Kootenay Lake, B.C. over the last 6 years. The Kootenai Tribe of Idaho only provides cost share funding for this work, the British Columbia Ministry of Forests, Lands and Natural Resource Operations (BCMFLNRO) is responsibile for all on-the-ground work and reporting related activities. Although some North Arm Kootenay Lake results are presented here, the Tribe does not provide funding for this portion of the lake.)

Sampling regime – A consistent, long-term array of 18 relatively equidistant transects crossing Kootenay Lake from east to west has been sampled to evaluate chemical and biological responses to nutrient addition in Kootenay Lake since North Arm fertilization began in 1992 (Figure 41).  This program is funded by the Fish and Wildlife Compensation Program – Columbia, BC Hydro and the Province of British Columbia. These same transects are used to evaluate the more recently BPA-funded South Arm nutrient addition program (funded by this project, BPA 199404900), which began adding nutrients in 2004. 

 image044

Figure 41. Sampling transects used to evaluate chemical and biological responses to nutrient addition. (Figure 1.1 from Schindler et al. 2008).

2. Objective of the Kootenay Lake Nutrient Restoration Program - Restoration of a disturbed ecosystem to its former state is the goal of this ongoing program. Since the beginning of experimental fertilization in 1992 for the North Arm of Kootenay Lake, the specific objective of this program has been to rebuild the kokanee salmon population by increasing lake productivity to a level that existed prior to 1950. Thus, this fertilization program has been tasked with ensuring a significant nutrient base to support zooplankton forage specifically for kokanee, which in turn support the lake’s large native salmonid piscivores. In cooperation with the Kootenai Tribe of Idaho, this program was expanded to include the South Arm in an effort in 2004 to restore South Arm kokanee in BC and Idaho.

3.  Hypotheses The South Arm fertilization program does not share the same specific, formal hypotheses regarding chemical and biological as found in the river biomonitoring portions of this project. However, restorative chemical and biological limnological issues, nutrient treatment, data collection, and analysis, are common to all geographic areas of the project. Furthermore, the long-term, annual post-treatment successes documented across trophic levels and years (presented below in the following results section) continue to justify the scientific approach to lake fertilization research, monitoring, and restoration implemented by this and other related in-basin provincial projects. 

       Results of North and South Arm Nutrient Restoration Programs 

  • Secchi disc measurements at all stations indicated a typical seasonal pattern of decreased spring transparency associated with increased phytoplankton biomass and turbidity from stream runoff, followed by increased transparency in the late summer and fall months. Nutrients added were in the form of liquid agricultural grade fertilizer (10-34-0, ammonium polyphosphate (phosphorus, P) and 28-0-0, urea ammonium nitrate (nitrogen, N)). The total amounts added in 2008 were 45.8 tonnes of phosphorus and 242 tonnes of nitrogen to the North Arm; 265 tonnes of nitrogen only were added to the South Arm. Total phosphorus concentrations ranged from 4 to 10 ug/L with the peak occurring in May. The results were similar amongst all sampling stations. Over the spring to fall sampling season, nitrate collected from integrated surface samples decreased, with the decline corresponding with phytoplankton uptake and utilization during summer stratification.
  • Over the past five years, vertically discrete water chemistry samples were taken to more accurately monitor nitrate concentrations in the photic zone. Nitrate is essential for maintaining optimal N:P ratios to ensure growth of edible phytoplankton. As expected, there was a seasonal decline in photic zone nitrate concentrations in July and August, followed by increasing concentrations in September.
  • Phytoplankton composition in integrated samples (0-20 m) was dominated by chrysophytes and crytophytes in the spring (April to June) and bacillariophytes from July onward. This pattern was also observed in the discrete phytoplankton samples (collected at 2, 5, 10, 15 and 20m). The trend of chrysophytes and cryptophytes being dominant in the spring and decreasing in the summer and fall months coincides with the increase in Daphnia spp. biomass, indicating grazing on phytoplankton is likely occurring. 
  • In 2008, zooplankton abundance and biomass in the main lake was similar to results from the previous year. Copepods dominated in the spring with Daphnia spp. being dominant in the late summer and fall months, a consistent trend seen in previous years. In the West Arm, there was a slight decrease in abundance and biomass, especially in Daphnia spp. compared to the previous year. 
  • The annual average mysid biomass at deep stations was slightly higher than in 2007. Mysid densities increased through the summer and then decreased into the fall, a trend seen in previous years. The average whole lake mysid values remain within pre-nutrient addition densities. 
  • Kokanee escapement to Meadow Creek increased to 940,000 fish compared to approximately 400,000 fish in 2007. The Lardeau River also had increased escapement with 409,000 fish, the largest return in the previous nine years. Spawner replacement numbers have largely exceeded a value of 1 since fertilization began, indicative of a sustainable spawning populations (Figure 42).

Figure 42. Recruit-spawner relationships for Lardeau River and Meadow Creek (1971-2008). Dotted line indicates replacement level of 1.0 (Figure 5.19 from Schindler et al. 2008).

  • The mean size of female and male kokanee from Meadow Creek was 25.4 cm and 25.9 cm, respectively. The long term average was 22.3 cm and 22.6 cm, respectively. Fecundity decreased from the 2007 results with 379 eggs/female (the long-term average was 265 eggs/female).
  • Spring hydroacoustic surveys indicated higher densities of fry in the North Arm compared to the South Arm. By fall, the distribution was fairly uniform throughout the lake, a trend observed in previous years. Fall hydroacoustic estimates for all age groups increased to 26.9 million (23 million was the estimate in 2007).
  • Biomass of kokanee in the lake has increased from 3.5 kg.ha-1 in the pre nutrient addition years to 9.6 kg.ha-1 since nutrient addition (Figure 43).

  • Results of the 2008 nutrient additions to the North and South arms indicated that trophic level response has been positive. Phytoplankton composition was suitable for growth of desirable zooplankton. Kokanee escapement and in-lake abundance increased, indicative of a positive response to the adaptive management of closely monitored seasonal applications of limiting macronutrients.
  • These recent results add another year of positive responses to a long successful set of positive information for the production and maintenance of kokanee in Kootenay Lake (Figure 44). While this figure represents kokanee production that is mainly due to the North Arm (Meadow Creek spawning channel), South Arm nutrient addition has assisted with improving foraging conditions (zooplankton availability) for kokanee in the lake as a whole. This and related metric time series clearly illustrates the efficient dose-dependent relationship between kokanee production, survival, and nutrient availability. For example, reduced nutrient loading from 1997 through 2000 and during 2004 resulted in immediate and proportional reductions in kokanee survival and abundance to further document the successful treatment effects of nutrient addition in Kootenay Lake.

 Multi-year cycles of kokanee age classes have also been observed following nutrient addition, suggestive of multivariate effects on inter-annual variation in Age-0 survival (Figure 45).

Summary

In addition to gains in overall ecosystem productivity, nutrient mitigation efforts have had significant and positive effects on numerous and, nearly all metrics measured by this project. Some Kootenai River positive examples include: no significant increases in ambient water nutrient loads or metals concentrations, significant increases in algal and macroinvertebrate species diversity and biomass, significant increases in desirable and edible types of algae (e.g. diatoms), significant increases in desirable/edible types of macroinvertebrate species (e.g. mayflies). Conversely, no increase in undesirable or potentially detrimental species of native or non-native fishes has occurred, especially species that could prey upon sensitive stages of the endangered Kootenai River white sturgeon. 

Similarly at Kootenay Lake post-nutrient addition positive metrics are abundant to include: significantly increased phytoplankton abundance and biomass, and, a suitable phytoplankton species composition for growth of desirable zooplankton species that in turn benefit kokanee salmon. Since nutrient addition commenced in the South Arm of Kootenay Lake in 2004, a tripling of native kokanee salmon and a doubling of rainbow trout biomass has occurred.

Lastly, significant numbers of kokanee salmon are starting to return to  South Arm Kootenay Lake tributaries, in Idaho and British Columbia, indicating that physical habitat restoration work on the tributaries, and, chemical-nutrient mitigation the main stem of the Kootenai River are working together to benefit the larger ecosystem.

Final Round ISRP Comment:

The ISRP noted the Kootenai River is one of the largest systems that has received long term nutrient additions and, therefore, is very important to monitor and report how the ecosystem is being altered. Smaller systems such as Kuparuk River in AK and the Keough River in BC are not directly comparable because of their smaller size. The connection to Kootenay Lake is a unique attribute since eventually the nutrients added to the river are going to accumulate in Kootenay Lake which is also being fertilized. Further, kokanee from the lake are likely to spawn only in lower tributaries, and the benefits of this “nutrient pump” farther upstream may be minimal.

Comments on specific responses

1. The sponsors state that a report “currently in progress, will update and combine previous reports from 2009 and 2010 with recent data covering water quality, algae, macroinvertebrates and fish. Reports will emphasize pre-nutrient and post nutrient addition periods (2003-2010). Findings, thus far, have continued to strongly support the positive benefits of nutrient addition to the Kootenai River biota (Holderman and Gidley 2011, In Prep.). Significant increases in primary, secondary, and tertiary productivity levels have been demonstrated”. The ISRP would like to see the latest draft of the report.

An on-line draft of the report was provided.

2. If tributaries are being used by rainbow trout in the Canyon reach what evidence exists that habitat conditions are limiting there as well in the main river where the nutrients are being added?

The response is satisfactory.

3. How far downstream are the nutrient benefits expected to be realized and will these benefits interact with the bioengineering work being done in the braided reach? Do the sponsors anticipate a nutrient spiraling effect?

In response to the ISRP question about the long-term plans for nutrient additions (i.e., sustainability of this restoration approach) the project sponsors indicated that they view continued nutrient addition as necessary to compensate for nutrients being sequestered above Libby Dam. However, the ISRP has a practical concern; namely, nutrient additions on this scale cannot go on forever. As well if Libby Dam is the source of the problem, why are the nutrient additions, at appropriate magnitudes and scales, not being done at Libby Dam? It seems that point of supplementation would be more appropriate from a system-scale perspective.

It seems that the use of stable isotopes signatures would be more effective in answering questions about downstream spiraling of nutrients, quantifying how far downstream the positive effects of the nutrient additions can be detected, and the pathway leading to whitefish. The sponsors should take a careful look at these methods to see if they would be more effective in terms of cost savings and better quantification of ecological processes. See above general comments regarding implications of downstream nutrient spiraling and upstream nutrient “pumping” from migrating kokanee. A rough estimate of the overall benefit of an increased kokanee population to nutrient dynamics of the river should be possible using pre Libby dam information on escapement levels and spawner distribution.

4. Is there a working model that sets the nutrient addition response in the context of the whole ecosystem? If so ISRP would like to see details on the model. Will the annual cost of $1.8 M be ongoing?

It is a major oversight not to have a working model that sets the nutrient response in the context of the whole ecosystem. This needs to be completed immediately; it should be the number one priority of the program.

The sponsors should consider using an “off the shelf” model such as Ecopath to provide an ongoing perspective on the trophodynamics of the ecosystems they are trying to restore with nutrient additions.

5. Whitefish seem to be responding to nutrient addition. What is their role in Kootenai River food web and could they be a food item for sturgeon?

The response is satisfactory. Given that the whitefish seem to be responding to the nutrient addition, their role in the food web is a key factor to understand.

The ISRP encourages investigations on feeding habits of top predators such as white sturgeon in the reaches where whitefish are available as food.

See also comment to response # 3 on possible use of stable isotopes as a tracer for whitefish food relationships.

6. Reports being prepared for publication were not provided although requested at the last ISRP review. At a minimum, the sponsors should provide a table with the publication title, key authors, target journal, and submission date.

Given the importance of this effort, the sponsors should improve their rate of publications, preferably in highly regarded professional ecosystem oriented journals. The KTOI and IDFG should be authoring joint publications. This would provide evidence of sustained collaboration.

7. Some of the protocols related to environmental and physiochemical sampling are not complete on the MonitoringMethods.org website, thereby making it difficult to evaluate. The ISRP would like to see a complete description of all protocols.

See comment below response # 8.

8. If changes in the monitoring protocols are anticipated in the future, the ISRP would like a description of them.

The current monitoring design does not appear to be well-suited to addressing the ISRP concerns about the spatial extent of the nutrient effect. The figures provided in the response to illustrate downstream responses (Figure 3.1, 3.2, 3.3, 3.4) do indicate that there is an increase in various biological parameters from the point of nutrient addition to sample site KR6. However, virtually every monitored parameter declines dramatically between KR6 and KR4. This decline also occurs during years prior to the addition of nutrients, raising the question of whether this change is due to a diminution of nutrient effects or change in some other factor that prevents the benefits from nutrient addition from being expressed. It is interesting that site KR4 is in the straight reach while the sites within the response reach are either in the canyon or braided reaches. Is it possible that the observed pattern in the monitored parameters is a response to change in physical habitat conditions rather than a lack of nutrients? It would seem that some investigation of the interaction between physical habitat conditions and response to nutrient enrichment should be incorporated into the monitoring effort to better understand this dynamic. Recognition that certain channel conditions are unresponsive to nutrient addition would be of critical importance in considerations for expanding nutrient enhancement of the Kootenai River. For example, the plan to increase P additions to achieve a concentration of 5 ug/L may not extend biological responses further downstream if factors other than nutrient availability are governing biological response.

9. More details are required on the particular relationships, at the working scientific level, between this project and the other three Kootenai River proposals.

There seems to be much overlap in what the various Kootenai River projects are doing as provided in the Table in the response. This suggests a need to consolidate the projects into one that can be carefully monitored for redundancies as well as overall restoration effectiveness and professional productivity. If consolidation is not possible or practical, frequent data synthesis is required. By this ISRP means actual merging of data sets between projects, not meeting to discuss separate results.

The ISRP appreciates that there is a Core Adaptive Management Team, a Modeling Team, a Policy Team, and a host of other teams and committees listed. However, the key aspect is how they interact and, more importantly, it should be clear who makes the important management decisions in this complex project. Essentially, they should have a standing scientific advisory committee that meets with them at least annually and offers them advice on program components, models, and research directions.

The draft Kootenai Subbasin Adaptive Management Plan was provided. However the sponsors state “The Kootenai River Habitat Restoration Program (KRHRP) adaptive management and monitoring program does not [sponsors’ underlining] specifically include metrics related to the biological response of the focal aquatic species populations”. These metrics are being collected in other projects/agencies and will be shared and evaluated in the context of the KRHRP monitoring and adaptive management plan. A procedure should be worked out to determine which of these several adaptive management plans, including that for the nutrient addition project, will be implemented, should there be disagreement about them. At present there does not seem to be an overarching adaptive management plan.

ISRP Retrospective Evaluation of Results

This proposal and project remain the broadest of the Kootenai River projects. The attention is to the whole ecosystem rather than to the more limited fish species components of other studies. The Kootenai Tribe of Idaho and Idaho Department of Fish and Game initiated a comprehensive, multi-trophic level and water quality monitoring program in 2000 to investigate the underlying problems of the Kootenai River ecosystem. The current ISRP review is the latest review for the project which is now somewhat narrower in focus, with specific emphasis on nutrient addition as a tool to increase resident salmonid production.

 In 2000, reviewers were not confident that all the issues to be studied have been thought through and they thought this was particularly true for the proposed nutrient addition study, which was viewed as inadequately planned. The study was described as too simplistic and short term and reviewers thought it probably should be dropped.

 Reviewers in 2007 were much more enthusiastic about the project and supported the work in an experimental phase. The proposal demonstrated much enthusiasm for ecosystem improvement with an impressive list of potential contributors. Integration had been accomplished by cooperative development of an ecosystem model and an adaptive management process.

 In 2012, the ISRP arrived at a similar conclusion as the 2000 reviewers. The proposal, and the response to questions raised, did not adequately address the ISRP specific major concern about the need for a model, or some other method, of integrating data being collected to evaluate the response of the river ecosystem to nutrient addition. A mechanism for synthesizing data would allow hypotheses about river response to nutrient enhancement to be refined through time and the monitoring protocols to be modified accordingly. As well, current ISRP reviewers recommended that the data obtained from this project, as well as the three other related Kootenai River programs, be integrated into a synthesis paper.

Qualification #1 - Qualification #1 - A model or some other method of integrating data being collected is required
A model or some other method of integrating data being collected is required to evaluate the response of the river as an integrated ecological system to nutrient addition. As a first step, a concise data synthesis report involving the other Kootenai River ecosystem restoration projects would allow hypotheses about river response to nutrient enhancement to be refined (see also qualifications for 200200200 - Kootenai River Habitat Restoration Program). Ideally, a peer reviewed article, in a well-regarded journal, should follow. Alternate hypotheses could be tested through time, and the monitoring protocols could be modified accordingly. The understanding of system response to nutrient addition that could be generated using an integrative process would also greatly enhance the effectiveness of adaptive management.

1. Purpose: Significance to Regional Programs, Technical Background, and Objectives

Significance:The proposal does not describe clearly enough the relationships among this project and the other major projects on the Kootenai for which proposals were submitted for this review cycle. It is connected with three other Kootenai proposals (198804900, Kootenai River Fishery Investigations; 200200200, Restore Natural Recruitment of Kootenai River White Sturgeon; 200200800, Reconnect Kootenai River with Historic Floodplain). These 3 projects should be highly integrated but there is no evidence of this level of collaboration in the proposal.

Technical background: Previous research has established the fact that nutrient availability is limiting productivity in the Kootenai River below Libby Dam. The premise of the current proposal as well as 200200800 (Reconnect Kootenai River with Historic Floodplain) is that increasing the basal productivity will increase tertiary level productivity for resident fish including rainbow trout, white sturgeon, and kokanee, for a long term ecosystem recovery of the river’s mainstem. The foundation for this project appears to be the energy budget developed by Synder and Minshall (2005) which showed that fish pooled data over several species may be limited by food. A major oversight, however, is the need for an ongoing model to guide the research and restoration. For example, it is not clear how spatially extensive the nutrient additions need to be before fish populations are reasonably restored or whether the costs will be prohibitive. Although this is an interesting experiment and the results are potentially useful, the ISRP concludes that the nutrient addition may not be feasible to maintain over the long term. In other words, nutrient addition is likely not a sustainable method of ecosystem recovery.

The ISRP noted there are no references to the success or failure of other attempts to increase fish production with long term fertilization in large rivers (Slaney et al. 1994) and small rivers (Keough, Salmon; see below) and numerous other references in the ISAB Food Web Report (ISAB 2011-1).

  • OBJ-1: System-wide Biomonitoring and Evaluation of the Mainstem Kootenai River

The objectives are clearly stated and directly relevant to restoration.

  • OBJ-2: Restore Ecosystem Productivity

The sponsors state, “Bottom-up productivity in the regulated mainstem of the Kootenai River was identified as a strong limiting factor to food web development in the river, ultimately resulting in reduced fisheries.” Holderman and Hardy (2004) is one of the papers quoted but there is no citation given. It is noteworthy however that the foundation paper for the work recognized the confounding effect of habitat when discussing fish in the context of the energy budget (Synder and Minshall 2005, page 482).

The nutrient addition work in the Canyon Reach is not accompanied by physical habitat restoration but there appears to be an expectation that the positive effects of nutrients will extend into the braided reach where very substantial bioengineering is occurring. This reach is at the downstream end of the nutrient effect footprint. It would be helpful to have this clarified.

  • OBJ-3: Provide Provisions to Restore Ecosystem Productivity to Kootenay Lake, B.C.

The lake component of the project seems to be successful. However the spawning channel is a confounding factor. The sponsors state,While …Figure 44. represents kokanee production that is mainly due to the North Arm (Meadow Creek spawning channel), South Arm nutrient addition has assisted with improving foraging conditions (zooplankton availability) for kokanee in the lake as a whole.” Although this is an interesting experiment and the results are potentially useful, the ISRP is concerned that the nutrient addition may not be feasible over the long term. In other words, nutrient addition is likely not a sustainable method of ecosystem recovery.

  • OBJ-4: Restoration and Monitoring of Key Kootenai River Tributary Segments

This objective focuses on tributaries downstream of Bonners Ferry. The ISRP learned there are a few tributaries above the Canyon reach, in Montana, that are used by rainbow trout (RBT). Are any of these used by the RBT populations targeted for nutrient enrichment? If so have habitat conditions in the tributaries been factored in as possibly limiting?

2. History: Accomplishments, Results, and Adaptive Management (ISRP Review of Results)

Accomplishments and Results: This project has a long history and much detail on the results of studies on nutrient dynamics and trophic productivity that have been completed was presented in the proposal. However, results are not provided in a meaningful way. While the sponsors provide abundant detail on results they fail to articulate key advances in understanding the ecological system or how the data have been used to improve management. Clearly, substantial effort should be spent to synthesize the advances to date and show how they have been used to improve management.

Further, as a general comment, while this proposal is labeled as "Ecosystem Restoration" and many of the system-scale components are under investigation, there is no attempt to examine the data at the ecosystem scale. That is, no model linking it all together or to guide and prioritize the research and restoration activities is presented. A working model is sorely needed.

The project started in 1994 but achievement of results is not clear. A synthesis of results or reference to peer reviewed publications is needed for ISRP review. Most of the results that have been published are in the grey literature, and those that are in journals do not deal with the key results documenting how the fish community has responded and on what scale has the response been observed.

The sponsors state that a report is currently in progress that will update and combine previous reports from 2009 and 2010 with recent data. It would be useful for the ISRP to see this draft

It would be helpful to have more information on the migratory traits of rainbow trout, the apparent target species, as this has a bearing on how far afield nutrient addition effects are projected. Results to date show growth of RBT, as reflected by condition factor, is only being influenced in the nutrient addition reach shown in Figure 22. However the significant increase in whitefish populations and growth of their younger ages is noteworthy. It might be worthwhile to investigate the role of whitefish in the food web of the Kootenai River in some detail. This might involve more collaboration between this project and 199806500 Kootenai River Fishery Investigations. Are whitefish a forage fish for white sturgeon?

Further documentation on lessons learned relative to this aspect from other systems would be instructive. For example, a case history on a fertilization project on the much smaller Keogh and Salmon Rivers in BC showed that the effective distance of fish growth resulting from nutrient additions was on average 15 km (Slaney et al 2003). The furthest downstream monitoring station on the Kootenai seems to be 40 km. Do the sponsors anticipate fish enhancement over these 40 km? What is the role of nutrient spiraling in this regard? The concept is not mentioned in the proposal.

Responses to Past ISRP Comments: The reports being prepared for publication were not provided. At a minimum, there should be a Table with the publication title, key authors, target journal, and submission date.

Adaptive Management: The process is adequate, for the most part, but lacks a guiding model and criteria for change. How are decision-makers incorporated so as to make large scale changes happen?

The ISRP’s Retrospective Report 2011 includes a recommendation on time frame for evaluating restoration projects (p. 68) which is very relevant:

“The ISRP therefore suggests that additional dialogue is needed between habitat managers, scientists, and policy-makers so that realistic timeframes can be established, and appropriate schedules agreed upon, to monitor and evaluate different types of restoration actions.”

Given that this project has been underway for 11 years, it is likely the additional dialogue is required soon.

3. Project Relationships, Emerging Limiting Factors, and Tailored Questions for Type of Work (hatchery, RME, tagging)

See above for comments on project relationships.

RME has been underway for several years, and according to the proposal an adaptive management approach reduced the number of treated sites by 50% without losing significant statistical power or representation. This assertion should be documented.

Emerging Limiting Factors:Climate and land use changes are superficially treated. There are numerous changes taking place and emerging at the local scale. The ISRP urges the sponsors to take these seriously by incorporating them into some of their planning and activities.

4. Deliverables, Work Elements, Metrics, and Methods

Deliverables and work elements generally appear to be appropriate for the project objectives. It appears that the nutrient application process, monitoring methods, and experimental design that have been used in the past will continue with this new project. However, this is not explicitly indicated in the proposal and very few details are provided about the monitoring effort going forward. This point should be clarified.

Restoring the Kootenai River and the Lower Kootenai Watershed to Pre-Impoundment Productivity Levels: The sponsors need to be specific about whether a food web analysis will be performed, how detailed it will be, and articulate how the results will be used to improve productivity. Although positive results have been obtained locally in terms of increasing trout biomass, although not to a statistically significant level, nutrients will need to be applied broadly to significantly improve total trout abundance and growth.

Work Elements: Considering all the work completed to date, is there an overriding model being developed that guides the research and restoration activities? If not, there should be as well as a peer-reviewed synthesis of the progress to date. Further, while the goals are well-articulated, when will they be achieved? A time line is needed for each objective.

Key Personnel: The sponsors have a good level of competence. Two items of concern are the heavy reliance on private consulting firms to do the work and the lack of publications in the peer-reviewed literature. The benefits from this project would increase if central personnel made peer-reviewed publications a priority. While reports are necessary, they are not sufficient for a program of this scope and importance.

4a. Specific comments on protocols and methods described in MonitoringMethods.org

Monitoring has been a major component of this study and needs to continue to be the focus with the implementation of this new phase of this effort. As noted for the Deliverables and Work Elements, the proposal implies that the methods to be used will be those that have been employed in the past. But the proposal does not indicate that this will be the case. If there are any changes in sampling or project design, these changes should have been fully described in the proposal.

Some of the protocols related to environmental and physiochemical sampling are not complete on the website, thereby making it difficult to evaluate. These need to be completed in the very near future.

Final Round ISRP Comment:
This is a worthwhile proposal that initially suffered from lack of reporting of results to support its continuation and expansion. The excellent response provided the necessary information and illustrates the kind of material that should be in the initial proposal. The problem identified is loss of productivity (at all ecosystem levels) as a result of land and water management practices, especially Libby Dam. Early studies have led to the conclusion that nutrients limit production of valuable fish populations. Fertilizer application is used experimentally in this project to test whether nutrients are limiting productivity at various levels in the Kootenai River ecosystem, including the fish. Justification includes the Fish and Wildlife Program, Kootenai subbasin plan, FWS BiOp for white sturgeon, and the Kootenai River Network. The narrative and tables on interactions with the several other projects on the Kootenai are helpful. The proposal demonstrates much enthusiasm for ecosystem improvement with an impressive list of potential contributors.

The response significantly answers the ISRP's concerns about the timing of the project with respect to experiments and implementation, and provides data and summary results for the work accomplished so far. The timeline in Table 1 is especially helpful, and we recommend that such a table be used in subsequent proposals and progress reports. It is clear now that this is a truly experimental phase and will continue to be so through the lifetime of this funding cycle. Results from the Kootenay Lake experiment still seem rather scant. Since phosphorus seems to be the limiting nutrient, we are still surprised that fertilization of the Kootenai River is heavy on nitrogen. Algae seem to have responded to nutrient addition, but the chemical results seem to require more interpretation. There was a useful discussion of other limiting factors and the multi-agency approach to evaluating them. The database development seems appropriate for assembling the results. The comprehensive discussion of fishery impacts since Libby Dam is informative and supportive of the existence of detrimental effects. Depleted nutrients are likely part of the picture, which justifies the well-planned research. The logic of planting kokanee eggs and creating a spawning channel is clearer in the response, but that work is still somewhat oddly placed in this proposal. The explanations of sampling sizes for monitoring help clarify this issue. The ISRP appreciates the additional clarifying information.

The Tribe understands the need for a hierarchical, within- and among-project adaptive management (AM) program to integrate its projects and other Kootenai River Subbasin projects. Therefore, for consistency among the Tribe’s BPA project proposal responses, this AM section response includes: 1) a summary of this project’s planned and implemented adaptive management activities, based on biological responses and information gained from this and other project actions; and 2) an overview of the Tribe’s developing Subbasin-scale Adaptive Management Plan (AMP), which provides the context and mechanism for successful, larger-scale AM. 1) Adaptive Management within the Ecosystem Restoration Project (BPA 199404900) Adaptive management has existed at the heart of the Kootenai River Ecosystem Restoration Project (BPA 199404900) from its very inception. This project was created as a logical outgrowth of a successful, adaptively managed Canadian nutrient addition project that began downstream in Kootenay Lake’s North Arm in 1992. After more than a decade of successful implementation in the northern section of Kootenay Lake, the British Columbia Ministry of Environment approached the Kootenai Tribe of Idaho as a co-managing entity to help fund nutrient additions to the South Arm. Since the Kootenai River provides up to 60% of the lake’s total inflow, the Tribe felt that helping to restore this portion of Kootenay Lake would be in their best interest, as it would benefit fish species (particularly native kokanee salmon) that migrate between the lake and upstream river segments in Idaho. Thus this project has provided funding aid to the Kootenay Lake South Arm nutrient addition effort since 2004. Currently the Lake effort and the associated upstream river nutrient addition program being implemented by this project are helping to offset 30 plus years of nutrient limitation in the ecosystem created by Libby Dam hydro-operations. Other examples of adaptive management practiced by the project includes utilizing an empirically based, small-scale nutrient experiment (mesocosm study) to aid the tribe in deciding to try a larger, whole-river nutrient addition experiment in the Kootenai River. Results from the mesocosm study (Hoyle 2003), and project related trophic level biomonitoring performed in the river (Holderman and Hardy 2004) were used to design and implement the current Kootenai River nitrification effort started in 2005. Finally, in a more current example of active AM, this project is closely monitoring an array of biological and chemical parameters and responses to the experimental nutrient addition since its implementation in 2005 (See Major Accomplisments section of this proposal for results). Based on our analyses, which suggest a limited range and magnitude of the current dosing effectiveness, the project is recommending an increase in the target dosing rate of phosphorus by approximately 40 percent (3 to 5 ug/l) to further the downstream effect range of nutrients. 2) The Kootenai River Subbasin-scale Adaptive Management Plan In addition to the specific adaptive management actions described above, the Tribe is currently developing a multi-project Subbasin AM Plan (AMP) that provides the needed framework to formally integrate the Tribe’s various programs and projects, and eventually those of regional collaborative projects (KTOI 2011). This Subbasin AMP will ultimately link and incorporate each of the projects within the Tribe’s Fish and Wildlife Program at the subbasin scale to better understand and adaptively manage how those projects collectively contribute to ecosystem restoration in the Kootenai River Subbasin. Beginning with the Tribe-sponsored Adaptive Environmental Assessment in the early 1990s and a series of draft AM plan outlines (e.g. Walters et al. 2005), the Subbasin-scale AMP, is intended to be a living document. As such, it will be refined and updated over time as new information becomes available, as results of previous restoration actions are realized, and as the Tribe’s Fish and Wildlife Program continues to mature. This developing Subbasin scale AMP provides the needed framework to formally integrate the Tribe’s various programs and projects, and eventually those of regional collaborative projects. It is not intended to replace or supersede the specific, detailed monitoring and evaluation or adaptive management components of the individual projects that make up the Tribe’s Fish and Wildlife Program. While implementation of this AMP may yield information that results in recommendations to modify individual project goals, objectives, or actions, those specific decisions would ultimately be made at a project level. The AMP is designed to support efficient and effective investigation, integration and coordination of the Tribe’s Fish and Wildlife Program so that over time the Fish and Wildlife Program’s component projects can be refined or modified in support of the Tribe’s vision of: “The Kootenai River and its floodplain as a healthy ecosystem with clean, connected terrestrial and aquatic habitats, which fully support traditional Tribal uses and other important societal uses”. Finally, this AMP is designed to be consistent with the core principles of the Kootenai Tribe’s Fish and Wildlife Program. Namely, that the approach to ecosystem restoration must be: 1) holistic, science-based, collaborative, consistent with tribal and cultural values, 2) inclusive of social and economic values, and 3) adaptively managed.

The Project Relationships tracked automatically in CBFish provide a history of how work and budgets move between projects. The terms "Merged" and "Split" describe the transfer of some or all of the Work and budgets from one or more source projects to one or more target projects. For example, some of one project's budget may be split from it and merged into a different project. Project relationships change for a variety of reasons including the creation of efficiency gains.
Project Relationships: None

Additional Relationships Explanation:

A. Geographic Region

All Kootenai Tribe of Idaho and Kootenai River Subbasin projects are interrelated to varying degrees. They are complementary by design and are integrated at multiple levels and time scales. First, all Tribe and other Kootenai River Basin projects share and collectively address the vision of the Subbasin Plan to: “establish and maintain a healthy ecosystem characterized by healthy, harvestable fish and wildlife populations, normative and/or natural physical and biological conditions, and sustainable human communities” (MFWP and KTOI 2004). (http://www.nwcouncil.org/fw/subbasinplanning/kootenai/plan/).

Secondly, all Tribe and other Kootenai Subbasin projects are related by their complementary inclusion as valuable components into the Kootenai/y Ecosystem Adaptive Management Plan (KTOI 2011).  Within this multidisciplinary AMP, all component projects address certain aspects of the Kootenai/y ecosystem (e.g. aquatic, riparian or terrestrial management, research, and restoration). Thus, the integration of all Kootenai Subbasin projects collectively addresses the aforementioned Subbasin vision, biological objectives, and strategies in the Subbasin Plan and in specific project proposals under different funding allocations or programs.

Thirdly, all the Tribe projects are related in that they address a common set of primary and secondary limiting factors that affect all Kootenai River biota. In terms of direct project relationships, the Tribe for many years now has been systematically integrating and addressing limiting factors within and among its projects, and among other coordinated, non-tribal projects in the Kootenai/y Subbasin. For example, in the 2004 Kootenai Subbasin Plan, the Tribe and collaborators identified three primary limiting factors: Impoundment and hydro operations, physical habitat alterations, and non-native species introductions.

(Non-native species introductions were included as a primary limiting factor reflecting Montana FWP’s concerns regarding non-native resident salmonid issues in the Subbasin).

A series of secondary limiting factors were further identified in the Kootenai Subbasin Plan (on Pages 25 and 26), which included relevant habitat and biological factors. These 11 habitat factors and 7 biological factors are currently being addressed by the suite of Tribal and non-tribal projects throughout the Subbasin in Montana, Idaho, and BC. A subset of these major and secondary limiting factors is being addressed by this project as they relate to nutrient addition and biological responses, and as they relate to objectives of other Tribal and non-tribal Kootenai/y Subbasin projects and programs.

To further integrate projects, subbasin projects and collaborators further assigned objectives to address one or more of these secondary limiting factors according to habitat type (mainstem, tributaries and reservoirs) and according to the six native focal fish species.

B. Similar Work

The Idaho Department of Fish and Game (IDFG) (BPA project # 198806500) is a co-managing agency of the nutrient restoration effort currently underway on the Kootenai River. IDFG personnel are responsible for the daily operations and maintenance of the nutrient addition tank site located near Leonia, MT. Additionally, the Tribe and IDFG work cooperatively to collect fisheries data at several locations to monitor the effects of the nutrient addition effort; and, hold an annual workshop to discuss research findings and ecosystem management options for the Kootenai River.

Montana Fish Wildlife and Parks (BPA Project 199500400) have recently done some underlying trophic level investigations in response to declining trout fisheries below Libby Dam in the last decade. The studies have centered around the effects of Didymosphenia geminata, a nuisance filamentous diatom, on primary and secondary productivity in reaches below the dam. Some evidence of deleterious effects on primary productivity and macroinvertebrates have been noted (Ryan Sylvester pers. comm.). In response to MTFWP efforts, the Army Corps of Engineers (Hoffman and Hoyle 2010) has initiated mesocosm testing to look into possible chemical effects of hydro-operations on lower trophic level biota, including algae and macroinvertebrates. The Tribe has provided the Corps with in-kind mesocosm support to include: equipment, logistical and operational expertise, and staffing labor support for the study.  

The mesocosm study in Montana could provide valuable insights for downstream river managers in Idaho concerning nutrient restoration work currently underway. Any future large-scale mitigation effort in Montana (e.g. nutrient additions) needs to be closely coordinated with other downstream mitigation efforts in Idaho (e.g. nutrient additions by this project). The Tribe and the Idaho Department  of Fish and Game have requested that proponents of these projects keep them abreast of findings and possible associated management actions.

Global Climate Change

Global climate change is being considered within the suite of Kootenai tribal projects regarding issues affecting the Kootenai River vertebrate and invertebrate assemblages and their supporting habitats.  Recent discussions have involved potential direct impacts to fish habitat and environmental conditions for other Kootenai river flora and fauna, as well as indirect impacts through the necessity to operate Libby Dam under changing precipitation and hydrological conditions caused by Global Climate Change.  For example, within the ISAB ‘s Climate Change Impacts on Columbia River Basin Fish and Wildlife, report, experts predict that global warming will result in more precipitation as rain and less as snow, earlier snowmelt,  earlier, higher spring flows, and warmer water temperatures in the Columbia Basin. These changes are predicted to significantly impact coldwater fish habitat throughout the basin. Thus, the loss, fragmentation, and isolation of coldwater fish habitats may necessitate operational modifications of coldwater storage reservoir operations throughout the basin including Libby Dam Reservoir (Lake Koocanusa).  However, as seen with past system operation requests (SORs) for thermally driven outflows from Libby Dam to affect river temperatures downstream for sturgeon and burbot, isothermal conditions in the reservoir forebay can, at times, nullify the desired downstream thermal effects of selective withdrawal operations.

In addition, subtle changes in native cool water fish assemblages and thermal habitat suitability, as well as potential increases in thermal suitability for warm water non-native fish species may result due to Climate Change.  However, it currently remains unclear whether or to what extent future operational changes in hydro-electric generating facilities, such as Libby Dam, will be able to compensate for predicted future shifts in regional atmospheric thermal regimes.

Thus, global climate change and its effects on regional atmospheric thermal regimes, precipitation patterns, and their corresponding effects on the hydrology and thermal regime in the river and reservoir ecosystem’s may have significant implications for the future of Kootenai River fish populations.  This project’s large- and fine-scale biomonitoring programs in the Kootenai River and the Kootenay Lake biomonitoring program are well designed to detect and track changes and trends in growth, biological condition, and other  biological and community features in response to future changes in regional climate.

Non-native species

This project’s current, comprehensive biomonitoring programs are also well positioned to detect the presence and future trends of invasive and non-native species across multiple trophic levels. Algae, invertebrate, macroinvertebrate, and fish species are comprehensively sampled across their respective communities with great detail paid annually to taxonomic composition of fish and invertebrate assemblages among all trophic levels. This useful feature should allow easy detection and monitoring of non-native species in the future.

Currently, several non-native fish species occur in  the Kootenai River (Holderman and Gidley 2011). However, they are very rare and most are warm water or lake dwelling species ((e.g.  pumpkinseed sunfish (Lepomis spp.), yellow perch (Perca flavescens), and bullhead catfish (Ameiurus melas)) that are not well adapted to a cold water river, such as exists in the Kootenai basin. Brown trout (Salmo trutta) are also present in the Kootenai River but are currently at extremely low population densities (< 0.1% of total catch from 2003 through 2003, n=108; See Table 3 Major Accomplishments section). S. trutta could present a challenge to river managers in the future due to its cold water preference and predaceous nature. This project will continue to monitor the status of brown trout and all other native and non-native species populations in the upcoming project cycle.

Presently the Tribe knows of no non-native algae, invertebrates (plankton, snails or clams) or macroinvertebrate species in the Kootenai River. Eurasian watermilfoil (Myriophyllum spicatum), a non-native aquatic macrophyte, has been documented in the Kootenai River. It is currently being monitored by the Idaho Dept. of Environmental Quality, which has developed (but not implemented) a control program.    

The native algae Didymosphenia geminata (Didymo) which in recent years has demonstrated an ability to reach nuisance levels in many areas of the world, including the Kootenai River watershed. Most of the outbreaks in the Kootenai River have occurred within a relatively short distance from outflow of Libby Dam  and have not spread to other areas of the watershed (Hoffman and Hoyle 2010). Didymo has been and will continue to be monitored by this and several other basin projects for possible outbreaks.

Please describe which opportunities have been explored to restore or reintroduce resident native fish and their habitats?
As stated earlier in this proposal, the goal of project 1994-049-00 is to recover a productive, healthy and biologically diverse Kootenai River ecosystem, with an emphasis on native fish species rehabilitation. The project is specifically designed to aid the recovery of important native fish stocks, such as white sturgeon, burbot, bull trout, kokanee and other regionally important salmonids. Several specific project activities are aimed to improve native fish populations including the provision of funding for nutrient additions to Kootenay Lake, British Columbia. This effort is largely aimed at increasing kokanee salmon abundance by boosting overall lake productivity. These fish are a keystone species within the larger Kootenai River ecosystem and are an important food resource for other native species such as white sturgeon, burbot, and bull and rainbow trout. Additionally the implementation of a large-scale nutrient addition effort on the main-stem Kootenai River is aimed to bolster system productivity at all biological trophic levels to include native fish. Mountain whitefish in particular have benefited greatly from these nutrient additions; they have doubled in abundance since the start of the effort in 2005 (Bull and rainbow trout in turn are likely benefiting from the increase in mountain whitefish and other non-game native forage species). Rainbow trout numbers (in Kootenay Lake and the Kootenai River, Idaho reaches) have increased by 30 and 50 percent respectively, and adult kokanee spawning abundance has increased by approximately 10 fold since the combined nutrient addition efforts to Kootenay Lake and the Kootenai River were initiated in 2004 and 2005, respectively. This project also has been involved in a decade-long habitat restoration and monitoring effort to restore key kokanee and trout spawning tributaries of the Kootenai River. This work, in combination with nutrient restoration efforts, is beginning to show very promising results in terms of kokanee escapement returns (mentioned above) and general habitat metric improvements such as a reduction in bank erosion and improved stream substrate health, which should benefit other native fishes in the Kootenai River basin.
Has a loss assessment been completed for your particular subbasin/or province?
No
Describe how the project addresses the loss assessment. If a loss assessment is in progress or being proposed, describe the status and scope of that work.
The Kootenai Tribe of Idaho is currently developing an operational loss assessment tool that the Tribe will use to assess and quantify losses associated with the operation of Libby Dam. This tool will also provide a framework that offers Columbia Basin fish and wildlife managers an opportunity to agree on operational loss methodologies and promote discussions that center on customizing the framework to meet specific Subbasin needs. The Kootenai River Operational Loss Assessment, Protection, Mitigation, and Rehabilitation (OpLoss) project (BPA 200201100) applies a structured series of biological and ecological evaluations to a post-impoundment large river-floodplain ecosystem, the Kootenai River system. This project takes a multidisciplinary approach to determining and quantifying floodplain ecosystem function losses resulting from the operation of Libby Dam. It also takes into context other ecological perturbations such as levee construction and floodplain loss. This project has a series of sequential phases: 1) Operational loss assessment 2) Habitat and population protection 3) Mitigation and restoration 4) Monitoring and adaptive management The project is currently in Phase 1, which is expected to be completed and undergo ISRP review in late summer 2012. Phase 1 includes: 1) characterizing past and present hydrological, ecological, and biological conditions involving a large number of biotic and abiotic metrics, analyses, and models within plant, invertebrate, and avian communities, 2) construction of a series of biotic and abiotic Indices of Integrity (IBIs); 3) combining multiple IBI’s into a single Index of Ecological Integrity (IEI), and 4) synthesizing the methodologies and analysis methods into an operational loss guide to establish a regionally accepted, transferable framework for operational loss assessments based on standardized quantitative ecological functions and conditions.
If you are using non-native fish species to achieve mitigation, have you completed an environmental risk assessment of potential negative impacts to native resident fish?
No
Please describe: for the production of non-native fish, what are the potential impacts on native fish populations, including predation, competition, genetic impacts, and food web implications?
This project is not using non-native fish species to achieve mitigation. The KTOI is interested in native fish restoration.
Does your proposed work support or implement a production goal identified in a USFWS Bull Trout Recovery Plan?
Yes
Please explain.
The goal of the 2002 USFWS Bull Trout Recovery Plan (Chapter 4, Kootenai River Recovery Unit) is to ensure the long-term persistence of self-sustaining, complex, interacting groups of bull trout distributed throughout the species native range. Specifically, the Kootenai River Recovery Unit Team adopted the goal of a net increase in bull trout abundance in this recovery unit (as measured by standards the recovery team develops), with restored distribution of any extirpated populations that the recovery unit team identified as necessary to recovery. In order to recover bull trout in the Kootenai River, the following objectives need to be met: • Maintain current distribution of bull trout and restore distribution in previously occupied areas within the Kootenai River Recovery Unit. • Maintain stable or increasing trends in abundance of bull trout in the Kootenai River Recovery Unit. • Restore and maintain suitable habitat conditions for all bull trout life history stages and strategies. • Conserve genetic diversity and provide opportunity for genetic exchange. This project addresses Recovery Measure 1 to protect, restore and maintain suitable habitat and the following associated tasks to support the production goal and objectives stated above: 1. Protect, restore, and maintain suitable habitat conditions for bull trout. 1.1 Reduce general sediment sources. 1.2 Identify barriers or sites of entrainment for bull trout and implement tasks to provide passage and eliminate entrainment. 1.2.2 Provide fish passage around diversions. 1.2.3 Eliminate culvert barriers. 1.2.4 Improve instream flows. 1.3 Identify impaired stream channel and riparian areas and implement tasks to restore their appropriate functions. 1.3.1 Conduct watershed problem assessments. 1.3.2 Revegetate denuded riparian areas. Revegetate to restore shade and canopy, riparian cover, and native vegetation in streams where investigation indicates such actions are likely to benefit native fish. Priority watersheds may include Idaho: Boundary Creek (Idaho and British Columbia), Deep Creek, Kootenai River, Long Canyon Creek, Parker Creek, and Trout Creek. 1.3.3 Improve grazing practices. Reduce negative effects of grazing with improved grazing management or riparian fencing where investigation indicates such actions are likely to benefit native fish. Priority watersheds may include Idaho: Boundary Creek (Idaho and British Columbia), Deep Creek, Long Canyon Creek, Parker Creek, and Trout Creek. 1.3.4 Restore stream channels. Conduct stream channel restoration activities where investigation indicates such actions are likely to benefit native fish. Priority watersheds may include Idaho: Boulder Creek, Boundary Creek (Idaho and British Columbia), Cow Creek, Katka Creek, Myrtle Creek, Parker Creek, and Smith Creek. 1.3.5 Improve instream habitat. Increase or improve instream habitat by restoring recruitment of large woody debris, pool development, or other appropriate components in streams where investigation indicates such actions are likely to benefit native fish. Priority watersheds may include Idaho: Boundary Creek (Idaho and British Columbia), Deep Creek, Fisher Creek, Long Canyon Creek, Myrtle Creek, Parker Creek, Smith Creek, and Trout Creek. 1.3.6 Minimize potential stream channel degradation.

What tools (e.g., guidance material, technologies, decision support models) are you creating and using that support data management and sharing?
In December 2003, Statistical Consulting Services (SCS) was commissioned to create, customize, maintain, and operate a Web-based relational database for Kootenai Tribe of Idaho (KTOI). This included incorporation and operation related to all trophic level data and associated information for BPA Ecosystem, Operational Loss, and Kootenai Lake projects. In consultation with the project managers, a dedicated computer system, hosted by a reputable firm, CI Host, was acquired for this purpose. An initial Web page was then constructed and customized as per specific requirements of the clients. Bio-monitoring trophic level data generated by various projects were formatted, collated, and uploaded into the designated components of the relational database, as they became available. Exploratory summary and graphical routines were subsequently implemented for each of the specified components, as specified by the clients. More sophisticated options, such as data censoring, multi-year-trophic level plotting displays, dynamic maps, etc, were then incorporated on needs/available funding basis. User profiles were also created, and security was implemented at a level requested and specified by the project sponsors. The KTOI fish and wildlife database has been operational since March 2004. The design of these WEB-based relational database systems allow specified users to access all data online as well as carry out some basic search, summary, censoring, and plotting routines. This design allows for independent access to each component as well as collective functionality for potential inter-trophic analyses. The Ecosystem database is designed around separate trophic level data components including algae, macroinvertebrates, fish, and water quality parameters, currently encompassing years 2001 to 2010. The current Kootenay Lake database includes components for water chemistry, phytoplankton, zooplankton, and mysid shrimp data covering years 2003 to 2009. Most recently, SCS has also incorporated data collected for the Fine-Scale Nutrient Addition Project, encompassing years 2005-2010 and consisting of water chemistry, chlorophyll, and periphyton data. Current Data Availability and Functionality: Currently, the Water component houses data encompassing years 2002 through 2010. Typically, data on all variables are uploaded, however, only a pre-specified list of variables (as determined by the client) is available for list, search, summary and plotting routines. At this time a total of 5585 observations are recorded. Variables include Site, Rep, NH4, NO2_3, SRP, TDP, TN, TP, and date, representing site code, replication number, ammonia nitrogen, nitrate and nitrite nitrogen, soluble reactive phosphorus, total dissolved phosphorus, total nitrogen, total phosphorus, and calendar date, respectively. In addition to the above nutrient variables, the water component also includes data on metals for the specified period, i.e. Aluminum, Arsenic, Cadmium, Copper, Iron, Lead, Mercury, Selenium, and Zinc. The algae component currently includes data for years 2001 through 2010. This component has been built as a three-tier component, consisting of information on chlorophyll, taxonomic groups, and ecological/biological metrics. There are a total of 2916, 38579, and 276 observations recorded, for each of the aforementioned sub-components, respectively. Variable list for the chlorophyll data include Site, Date, Replication, River Kilometers (RKM), Chlorophyll a, Chlorophyll a accrual rate, Total chlorophyll , and Total chlorophyll accrual rate. Variable list for taxonomic groups, diatom and soft-body, includes Site, Date, Taxa group, and Abundance. There are numerous variables listed under the metrics sub-component, including various Abundance, Richness, Dominance and Diversity measures, and other physical and biological indices. The list, search, summary, and advanced plotting routines are currently available for the algae component of the relational database. The Macroinvertebrate component of the relational database system currently houses data encompassing years 2000-2009. The 2010 data are being sorted, identified and processed at this time, and will subsequently be incorporated. Similar to the algae component, the macroinvertebrate component is a three-tiered one, consisting of aggregated, taxonomic and metrics data. There are a total of 2293, 342535, and 2243 observations recorded, for each of the aforementioned sub-components, respectively. Variable list for the aggregated macroinvertebrate data include Site, Date, Replication, River Kilometers (RKM), abundance and biomass. Variable list for taxonomic data includes Site, Date, Replication, Taxa group, Abundance, and Biomass. As was the case for the algae data, variables listed under the metrics sub-component of the macroinvertebrates includes various Abundance, Richness, Community composition, Functional group, and Diversity measures, as well as other biotic indices. The list, search, summary, and more advanced plotting routines are currently available for the macroinvertebrate component. The Fish component of the relational database system currently includes data encompassing years 2002-2010. The 2011 data are being collected, sorted, and processed at the time of writing this report. Similar to the algae and macroinvertebrate components, the fish component of the relational database system is also three-tiered, consisting of aggregated, individual, and fish gut content information. Data on fish age, encompassing years 2002 through 2008 have also been collated and incorporated into a new fish sub-component of the relational database. There are a total of 1454, 17087, and 75458 observations recorded, for each of the aforementioned sub-components respectively, and 2600 observations available for the fish age data. Variable list for the aggregated fish data include Site, Date, Species, Sampling effort, Fish condition, Fish length, and Fish weight. Variable list for the individual fish data includes the same information based on each individual fish species observation. Variable list for the fish gut content includes Site, Date, Species (note: predominantly Mountain Whitefish), Content Taxa, and corresponding, Abundance, and Biomass. The fish component of the relational database is rather complete and sophisticated, and will soon be augmented by additional valuable information such as fish length to age and relative weight. All system functionality, including list, search, summary, data censoring, and advanced plotting routines are currently available for this component. The Fine-Scale nutrient addition project was designed to monitor the potential water chemistry changes due to the addition of 3.0 .g•L-1 phosphorous, and assess algal production responses in the main-stem of Kootenai River. This project was designed to supplement the water chemistry and algal sampling of the KTOI bio-monitoring sites. The trophic level data available for the Fine-Scale nutrient addition project encompass years 2005 through 2010. The list of variables for the periphyton data includes Site, Date, Taxonomic groups, and Abundance. Currently, only the list and search options are available for this component. Basic summary and plotting routines will be implemented in near future. SCS started incorporating trophic level data generated by the Kootenai Lake Project into the Ecosystem relational database in the fall of 2007. The Kootenai Lake project is a component project of the larger Kootenai River Ecosystem Restoration Project. It involves mitigation of cultural oligotrophication to restore kokanee and other native fish populations, and restoration of habitats and supporting ecosystem functions in the South Arm of Kootenay Lake. This database includes various trophic components of limnological data from Kootenai Lake, including kokanee hydroacoustic surveys, and kokanee spawning escapement numbers from South Arm Kootenai Lake tributaries. Specifically, the current Kootenai Lake database includes components for water chemistry, phytoplankton, zooplankton, and mysid shrimp data covering years 2003 to 2009.

Data and Information for Water Quality, Primary, Secondary, and Tertiary productivity in the Kootenai River (DELV-1)
This proposed deliverable will cover all sampling, lab analyses, data storage and management, statistical and biological analyses and reporting of results for selected water quality, primary (algae), secondary (macroinvertebrate and zooplankton), and tertiary (fish community) parameters. Most of the work will be performed in a 300 km stretch of the main-stem Kootenai River, with some work in selected tributaries where key focal fish species carry out portions of their life cycles. Additionally, a good portion of the work will focus on monitoring of the Kootenai River nutrient addition effort, and, other planned mitigation efforts (e.g. river habitat work) to begin within this proposal cycle. Key personnel and associated duties are: Charlie Holderman, project management; Genny Hoyle, field collections, sample logistics, and data analyses and reporting; Bahman Shafii, statistical analyses, database management; Paul Anders, ecological analyses and technical report development; and associated scientific laboratories that analyze project samples.

We propose to continue the monitoring of key water quality, algae, macroinvertebrate, and fish community parameters in the Kootenai River and key tributaries. For the large-scale basin wide biomonitoring effort, monthly water quality, algae, and macroinvertebrate samples will be collected at 9 sites within distinct reaches of the Kootenai River ecosystem from Libby Dam, MT to Kootenay Lake, British Columbia during the biologically productive seasons (April to September). Fish community dynamics will be assessed once yearly during September at seven sites along the Kootenai River. Five sites are in Idaho, one site is in Montana (a shared site with Montana Department of Fish, Wildlife, and Parks), and an unregulated-river site will be sampled at Wardner, B.C..

For the direct monitoring of the nutrient addition effort, weekly water quality and bi-weekly algae monitoring directly related to the nutrient restoration experiment. Eight sites, two kilometers apart, will be monitored for key nutrients, algae taxonomy, and chlorophyll biomass. Sampling is proposed from June through September of each year.

To achieve this deliverable the project will use the following services: water quality analyses will be performed by Aquatic Research, Inc., Seattle, WA; algal chlorophyll and biomass will be determined by the University of Idaho Analytical Sciences Lab in Moscow, ID. Macroinvertebrate samples will be processed by EcoAnalyst, Inc. of Moscow, ID; and algal taxonomy information will be provided by Aquatic Taxonomy Services, Malinta, OH and, EcoAnalyst, Inc. of Moscow, ID.

Yearly information generated by this monitoring program will be organized and sent to the database manger by project staff and the project manager. The database management (uploading to web site and some Quality Control measures) is conducted by Statistical Consulting Services, Inc. based in Clarkston, WA.

Water quality, algal, macroinvertebrate, and fish community variables will be analyzed for sample size and other basic statistical properties that assist the project management with on-the-ground ecologically based management of mitigation options, etc. Reporting and recommendations will be made for trophic level and water quality sample size protocols. Biological analyses and interpretations for trophic-level data and water quality will be carried out by the project P.I., or contracted to qualified key personnel, and reported in annual documents to include peer reviewed scientific journals.
Types of Work:

Restoring the Kootenai River and the Lower Kootenai Watershed to Pre-Imoundment Producivity Levels (DELV-2)
This proposed deliverable will include the continuation of a nutrient restoration efforts on the main stem of the Kootenai River Implementation of this deliverable will be performed in conjunction with The Idaho Department of Fish and Game (IDFG, co-management agency). Day to day nutrient addition site operations and maintenance will be carried out by IDFG personnel (Cathy Gidley, Senior Fisheries Biologist, and crew) in a cost-sharing partnership with the Tribe. The funding for the nutrient purchases and for system engineering oversight by key contracting personnel (Dr. Peter Ward and Hassen Yassien; Ward and Associates Ltd.) will be provided by the Kootenai Tribe of Idaho. The nutrient site will be operational yearly from June to the end of September. Ward and Associates Ltd. will make 3 visits during this time to ensure the nutrient drip system is working properly and is calibrated with flow curves, etc.

Approximately 12,000 to 17,000 USG of liquid nutrients (typically phosphorus, occasionally nitrogen) need to be added to the river annually to achieve the target goal of 3.0 ug/l of phosphorus.

A foodweb analysis maybe be performed during this funding cycle. A foodweb specialist will be contracted for this work.

The work required for this deliverable will be periodic collections of water quality, primary (algae), secondary (macroinvertebrate and zooplankton), and tertiary (fish community) parameters in key spawning tributaries of the lower Kootenai River. Most of the work will be performed four in tributaries on a 3 year basis. Key focal fish species including kokanee salmon, burbot, bull and rainbow trout will be monitored.


We propose to continue the monitoring of key water quality, algae, macroinvertebrate, and fish community parameters in selected tributaries. Seasonal water quality, primary, and secondary productivity measures will be collected at 3 sites on each tributary. Fish community dynamics will be assessed once yearly during September at one site on each tributary.

Objective: System-wide Biomonitoring and Evaluation of the Mainstem Kootenai River (OBJ-1)

Project Deliverables How the project deliverables help meet this objective*

Data and Information for Water Quality, Primary, Secondary, and Tertiary productivity in the Kootenai River (DELV-1) Data obtained through the system-wide biomonitoring and evaluation effort will provide project management with critical data at lower trophic levels needed for successful ecosystem-level fisheries management. Currently the tribe is using it's biomonitoring information to guide the nutrient restoration effort underway on the main-stem of the Kootenai River. Water quality information (i.e. nutrient levels) are used to determine if the dosing system is working properly, and to estimate uptake by primary producers. Primary and secondary productivity data is also used to understand if nutrients are making their way through the food-web and utimatley increasing fish production levels. Fish community information is critical to understanding how mitigation efforts (e.g. nutrients, habitat improvements) are effecting fish species dynamics, such as abundance, bioimass, length at age, and population strength, etc. Cumulatively, this information is and will be used to adaptively manage the Tribe's Kootenai River Ecosystem Restoration Project in the upcoming funding cycle. These monitoring efforts will continue through the next proposed budget cycle (2013-2018) in there current forms. However, efforts will be made to review and improve monitoring efforts during the budget cycle.


Objective: Restore Ecosystem Productivity (OBJ-2)

Project Deliverables How the project deliverables help meet this objective*

Restoring the Kootenai River and the Lower Kootenai Watershed to Pre-Imoundment Producivity Levels (DELV-2) The additions of limiting nutrients to the Kootenai River has produced significant increases in all trophic levels of the river, including fish. These significant gains in productivity have brought the regulated Idaho reaches of the river back to a level likely not seen for 30 or more years. In general, sections of the river in Idaho are on par (primary productivity; fish biomass) with levels observed in the unregulated upstream reaches of the river in British Columbia. However, other reaches, such as the lower Kootenai River meander reach downstream of Bonners Ferry, Idaho have not seen significant increases in system productivity. Continued work perfomed through this objective will help to increase productivity in areas currently not, or only marginally benefitting from nutrient restoration.


Objective: Restore Ecosystem Productivity to Kootenay Lake, B.C. (OBJ-3)

Project Deliverables How the project deliverables help meet this objective*

Provide Provisions to British Columbia Ministry of Forests, Lands and Natural Resource Operations for Ecosystem Restoration (DELV-3) Similar to the nutrient restoration effort on the Kootenai River, the nutrient additions to the south arm of Kootenay Lake have had strong, positive effects on the food web, including increases in key fish species. Kokanee salmon, a native fish to the Kootenai River ecosystem, in particular has been fitted from the combined river and lake nutrient additions (see Major Accomplishments section). These fish are believed to be a keystone species within the ecosystem, serving as both a nutrient vector between Kootenay Lake and spawning tributaries in Idaho, and as an food source for other important basin fish species such as Kootenai River white sturgeon, burbot, bull and rainbow trout. Adult kokanee spawning numbers in key tributaries of the lower Kootenai River watershed have increased approximately 10 fold (see Major Accomplishments section) since nutrient additions started in 2004 in Kootenay Lake. The tribe believes the two nutrient addition projects (Kootenai River and Kootenay Lake) in conjunction with habitat improvements efforts in selected tributaries, are working to benefit important basin fish species that spend portions of their life cycle in the river, lake and tributaries.


Objective: Restore Historically Important Kootenai River Tributary Segments for Key Focal Species (OBJ-4)

Project Deliverables How the project deliverables help meet this objective*

Improved Fisheries Habitat in Key Kootenai River Tributary Segments that Support Key Native Fish Species (DELV-4) The tribe has been engaged in habitat restoration work and associated monitoring of key tributary segments for the last decade. The habitats contain critical spawning and rearing habitats for kokanee salmon, and several trout species, including bull trout. The implementation of a grazing management plan and off-stream water systems has eased livestock disturbances, and, along with grass, forb, and shrub/tree planting, improved bank stability and in-stream habitat metrics such as cobble embeddedness and salmonid spawning substrate conditions. Adult kokanee salmon spawning numbers, in several tributaries, have increased by 10 fold in the last 10 years. The tribe believes that this work combined with nutrient supplementation efforts in both the Kootenai River and Kootenay Lake is working to increase overall ecosystem productivity and habitat conditions for key fish species. Since most of the habitat improvement work has been completed during the last decade, we are proposing to continue with periodic (2-3 year basis) ecosystem-level, trophic monitoring to gauge tributary health, productivity, and focal fish species abundance. This would also include yearly survey of adult kokanee spawning numbers.

Major Facilities and Equipment explanation:
All field-research and non-contracted lab and analysis work will be based out of the Kootenai Tribe Fish and Wildlife Headquarters in Bonners Ferry, ID. The KTOI currently houses necessary labor and logistical support (labor, technical advise) and major equipment (boats, trucks,). Also the Field station facilities of the Idaho Department of Fish and Game, Bonners Ferry, are available for project meetings and equipment storage related to the co-managed nutrient addition effort. Project funding provided to the British Columbia Ministry of Environment (BCME) for Kootenay Lake restoration work will be performed by BCME personnel and equipment based in Nelson, British Columbia. Most sample analyses (i.e. water quality, chlorophyll, algal taxonomy, and macroinvertebrates) will be conducted by sub-contracted personnel at their perspective laboratories. Nutrient additions will be based out of the nutrient addition tank farm located near Leonia, MT. The facility can store upwards of 17,000 gallons of liquid fertilizer which are housed in industrial grade PVC, 2200 gallon tanks. Delivery of controlled amounts of nutrient solution to the Kootenai River are made using a solar-powered and gravity fed system capable of discharges of up to 40 L/hour of either nitrogen or phosphorus.

Review: Resident Fish, Regional Coordination, and Data Management Category Review

Independent Scientific Review Panel Assessment

Assessment Number: 1994-049-00-ISRP-20120215
Project: 1994-049-00 - Kootenai River Ecosystem Restoration (Nutrient and Biomonitoring)
Review: Resident Fish, Regional Coordination, and Data Management Category Review
Proposal Number: RESCAT-1994-049-00
Completed Date: 4/13/2012
Final Round ISRP Date: 4/3/2012
Final Round ISRP Rating: Meets Scientific Review Criteria (Qualified)
Final Round ISRP Comment:

The ISRP noted the Kootenai River is one of the largest systems that has received long term nutrient additions and, therefore, is very important to monitor and report how the ecosystem is being altered. Smaller systems such as Kuparuk River in AK and the Keough River in BC are not directly comparable because of their smaller size. The connection to Kootenay Lake is a unique attribute since eventually the nutrients added to the river are going to accumulate in Kootenay Lake which is also being fertilized. Further, kokanee from the lake are likely to spawn only in lower tributaries, and the benefits of this “nutrient pump” farther upstream may be minimal.

Comments on specific responses

1. The sponsors state that a report “currently in progress, will update and combine previous reports from 2009 and 2010 with recent data covering water quality, algae, macroinvertebrates and fish. Reports will emphasize pre-nutrient and post nutrient addition periods (2003-2010). Findings, thus far, have continued to strongly support the positive benefits of nutrient addition to the Kootenai River biota (Holderman and Gidley 2011, In Prep.). Significant increases in primary, secondary, and tertiary productivity levels have been demonstrated”. The ISRP would like to see the latest draft of the report.

An on-line draft of the report was provided.

2. If tributaries are being used by rainbow trout in the Canyon reach what evidence exists that habitat conditions are limiting there as well in the main river where the nutrients are being added?

The response is satisfactory.

3. How far downstream are the nutrient benefits expected to be realized and will these benefits interact with the bioengineering work being done in the braided reach? Do the sponsors anticipate a nutrient spiraling effect?

In response to the ISRP question about the long-term plans for nutrient additions (i.e., sustainability of this restoration approach) the project sponsors indicated that they view continued nutrient addition as necessary to compensate for nutrients being sequestered above Libby Dam. However, the ISRP has a practical concern; namely, nutrient additions on this scale cannot go on forever. As well if Libby Dam is the source of the problem, why are the nutrient additions, at appropriate magnitudes and scales, not being done at Libby Dam? It seems that point of supplementation would be more appropriate from a system-scale perspective.

It seems that the use of stable isotopes signatures would be more effective in answering questions about downstream spiraling of nutrients, quantifying how far downstream the positive effects of the nutrient additions can be detected, and the pathway leading to whitefish. The sponsors should take a careful look at these methods to see if they would be more effective in terms of cost savings and better quantification of ecological processes. See above general comments regarding implications of downstream nutrient spiraling and upstream nutrient “pumping” from migrating kokanee. A rough estimate of the overall benefit of an increased kokanee population to nutrient dynamics of the river should be possible using pre Libby dam information on escapement levels and spawner distribution.

4. Is there a working model that sets the nutrient addition response in the context of the whole ecosystem? If so ISRP would like to see details on the model. Will the annual cost of $1.8 M be ongoing?

It is a major oversight not to have a working model that sets the nutrient response in the context of the whole ecosystem. This needs to be completed immediately; it should be the number one priority of the program.

The sponsors should consider using an “off the shelf” model such as Ecopath to provide an ongoing perspective on the trophodynamics of the ecosystems they are trying to restore with nutrient additions.

5. Whitefish seem to be responding to nutrient addition. What is their role in Kootenai River food web and could they be a food item for sturgeon?

The response is satisfactory. Given that the whitefish seem to be responding to the nutrient addition, their role in the food web is a key factor to understand.

The ISRP encourages investigations on feeding habits of top predators such as white sturgeon in the reaches where whitefish are available as food.

See also comment to response # 3 on possible use of stable isotopes as a tracer for whitefish food relationships.

6. Reports being prepared for publication were not provided although requested at the last ISRP review. At a minimum, the sponsors should provide a table with the publication title, key authors, target journal, and submission date.

Given the importance of this effort, the sponsors should improve their rate of publications, preferably in highly regarded professional ecosystem oriented journals. The KTOI and IDFG should be authoring joint publications. This would provide evidence of sustained collaboration.

7. Some of the protocols related to environmental and physiochemical sampling are not complete on the MonitoringMethods.org website, thereby making it difficult to evaluate. The ISRP would like to see a complete description of all protocols.

See comment below response # 8.

8. If changes in the monitoring protocols are anticipated in the future, the ISRP would like a description of them.

The current monitoring design does not appear to be well-suited to addressing the ISRP concerns about the spatial extent of the nutrient effect. The figures provided in the response to illustrate downstream responses (Figure 3.1, 3.2, 3.3, 3.4) do indicate that there is an increase in various biological parameters from the point of nutrient addition to sample site KR6. However, virtually every monitored parameter declines dramatically between KR6 and KR4. This decline also occurs during years prior to the addition of nutrients, raising the question of whether this change is due to a diminution of nutrient effects or change in some other factor that prevents the benefits from nutrient addition from being expressed. It is interesting that site KR4 is in the straight reach while the sites within the response reach are either in the canyon or braided reaches. Is it possible that the observed pattern in the monitored parameters is a response to change in physical habitat conditions rather than a lack of nutrients? It would seem that some investigation of the interaction between physical habitat conditions and response to nutrient enrichment should be incorporated into the monitoring effort to better understand this dynamic. Recognition that certain channel conditions are unresponsive to nutrient addition would be of critical importance in considerations for expanding nutrient enhancement of the Kootenai River. For example, the plan to increase P additions to achieve a concentration of 5 ug/L may not extend biological responses further downstream if factors other than nutrient availability are governing biological response.

9. More details are required on the particular relationships, at the working scientific level, between this project and the other three Kootenai River proposals.

There seems to be much overlap in what the various Kootenai River projects are doing as provided in the Table in the response. This suggests a need to consolidate the projects into one that can be carefully monitored for redundancies as well as overall restoration effectiveness and professional productivity. If consolidation is not possible or practical, frequent data synthesis is required. By this ISRP means actual merging of data sets between projects, not meeting to discuss separate results.

The ISRP appreciates that there is a Core Adaptive Management Team, a Modeling Team, a Policy Team, and a host of other teams and committees listed. However, the key aspect is how they interact and, more importantly, it should be clear who makes the important management decisions in this complex project. Essentially, they should have a standing scientific advisory committee that meets with them at least annually and offers them advice on program components, models, and research directions.

The draft Kootenai Subbasin Adaptive Management Plan was provided. However the sponsors state “The Kootenai River Habitat Restoration Program (KRHRP) adaptive management and monitoring program does not [sponsors’ underlining] specifically include metrics related to the biological response of the focal aquatic species populations”. These metrics are being collected in other projects/agencies and will be shared and evaluated in the context of the KRHRP monitoring and adaptive management plan. A procedure should be worked out to determine which of these several adaptive management plans, including that for the nutrient addition project, will be implemented, should there be disagreement about them. At present there does not seem to be an overarching adaptive management plan.

ISRP Retrospective Evaluation of Results

This proposal and project remain the broadest of the Kootenai River projects. The attention is to the whole ecosystem rather than to the more limited fish species components of other studies. The Kootenai Tribe of Idaho and Idaho Department of Fish and Game initiated a comprehensive, multi-trophic level and water quality monitoring program in 2000 to investigate the underlying problems of the Kootenai River ecosystem. The current ISRP review is the latest review for the project which is now somewhat narrower in focus, with specific emphasis on nutrient addition as a tool to increase resident salmonid production.

 In 2000, reviewers were not confident that all the issues to be studied have been thought through and they thought this was particularly true for the proposed nutrient addition study, which was viewed as inadequately planned. The study was described as too simplistic and short term and reviewers thought it probably should be dropped.

 Reviewers in 2007 were much more enthusiastic about the project and supported the work in an experimental phase. The proposal demonstrated much enthusiasm for ecosystem improvement with an impressive list of potential contributors. Integration had been accomplished by cooperative development of an ecosystem model and an adaptive management process.

 In 2012, the ISRP arrived at a similar conclusion as the 2000 reviewers. The proposal, and the response to questions raised, did not adequately address the ISRP specific major concern about the need for a model, or some other method, of integrating data being collected to evaluate the response of the river ecosystem to nutrient addition. A mechanism for synthesizing data would allow hypotheses about river response to nutrient enhancement to be refined through time and the monitoring protocols to be modified accordingly. As well, current ISRP reviewers recommended that the data obtained from this project, as well as the three other related Kootenai River programs, be integrated into a synthesis paper.

Qualification #1 - Qualification #1 - A model or some other method of integrating data being collected is required
A model or some other method of integrating data being collected is required to evaluate the response of the river as an integrated ecological system to nutrient addition. As a first step, a concise data synthesis report involving the other Kootenai River ecosystem restoration projects would allow hypotheses about river response to nutrient enhancement to be refined (see also qualifications for 200200200 - Kootenai River Habitat Restoration Program). Ideally, a peer reviewed article, in a well-regarded journal, should follow. Alternate hypotheses could be tested through time, and the monitoring protocols could be modified accordingly. The understanding of system response to nutrient addition that could be generated using an integrative process would also greatly enhance the effectiveness of adaptive management.

1. Purpose: Significance to Regional Programs, Technical Background, and Objectives

Significance:The proposal does not describe clearly enough the relationships among this project and the other major projects on the Kootenai for which proposals were submitted for this review cycle. It is connected with three other Kootenai proposals (198804900, Kootenai River Fishery Investigations; 200200200, Restore Natural Recruitment of Kootenai River White Sturgeon; 200200800, Reconnect Kootenai River with Historic Floodplain). These 3 projects should be highly integrated but there is no evidence of this level of collaboration in the proposal.

Technical background: Previous research has established the fact that nutrient availability is limiting productivity in the Kootenai River below Libby Dam. The premise of the current proposal as well as 200200800 (Reconnect Kootenai River with Historic Floodplain) is that increasing the basal productivity will increase tertiary level productivity for resident fish including rainbow trout, white sturgeon, and kokanee, for a long term ecosystem recovery of the river’s mainstem. The foundation for this project appears to be the energy budget developed by Synder and Minshall (2005) which showed that fish pooled data over several species may be limited by food. A major oversight, however, is the need for an ongoing model to guide the research and restoration. For example, it is not clear how spatially extensive the nutrient additions need to be before fish populations are reasonably restored or whether the costs will be prohibitive. Although this is an interesting experiment and the results are potentially useful, the ISRP concludes that the nutrient addition may not be feasible to maintain over the long term. In other words, nutrient addition is likely not a sustainable method of ecosystem recovery.

The ISRP noted there are no references to the success or failure of other attempts to increase fish production with long term fertilization in large rivers (Slaney et al. 1994) and small rivers (Keough, Salmon; see below) and numerous other references in the ISAB Food Web Report (ISAB 2011-1).

  • OBJ-1: System-wide Biomonitoring and Evaluation of the Mainstem Kootenai River

The objectives are clearly stated and directly relevant to restoration.

  • OBJ-2: Restore Ecosystem Productivity

The sponsors state, “Bottom-up productivity in the regulated mainstem of the Kootenai River was identified as a strong limiting factor to food web development in the river, ultimately resulting in reduced fisheries.” Holderman and Hardy (2004) is one of the papers quoted but there is no citation given. It is noteworthy however that the foundation paper for the work recognized the confounding effect of habitat when discussing fish in the context of the energy budget (Synder and Minshall 2005, page 482).

The nutrient addition work in the Canyon Reach is not accompanied by physical habitat restoration but there appears to be an expectation that the positive effects of nutrients will extend into the braided reach where very substantial bioengineering is occurring. This reach is at the downstream end of the nutrient effect footprint. It would be helpful to have this clarified.

  • OBJ-3: Provide Provisions to Restore Ecosystem Productivity to Kootenay Lake, B.C.

The lake component of the project seems to be successful. However the spawning channel is a confounding factor. The sponsors state,While …Figure 44. represents kokanee production that is mainly due to the North Arm (Meadow Creek spawning channel), South Arm nutrient addition has assisted with improving foraging conditions (zooplankton availability) for kokanee in the lake as a whole.” Although this is an interesting experiment and the results are potentially useful, the ISRP is concerned that the nutrient addition may not be feasible over the long term. In other words, nutrient addition is likely not a sustainable method of ecosystem recovery.

  • OBJ-4: Restoration and Monitoring of Key Kootenai River Tributary Segments

This objective focuses on tributaries downstream of Bonners Ferry. The ISRP learned there are a few tributaries above the Canyon reach, in Montana, that are used by rainbow trout (RBT). Are any of these used by the RBT populations targeted for nutrient enrichment? If so have habitat conditions in the tributaries been factored in as possibly limiting?

2. History: Accomplishments, Results, and Adaptive Management (ISRP Review of Results)

Accomplishments and Results: This project has a long history and much detail on the results of studies on nutrient dynamics and trophic productivity that have been completed was presented in the proposal. However, results are not provided in a meaningful way. While the sponsors provide abundant detail on results they fail to articulate key advances in understanding the ecological system or how the data have been used to improve management. Clearly, substantial effort should be spent to synthesize the advances to date and show how they have been used to improve management.

Further, as a general comment, while this proposal is labeled as "Ecosystem Restoration" and many of the system-scale components are under investigation, there is no attempt to examine the data at the ecosystem scale. That is, no model linking it all together or to guide and prioritize the research and restoration activities is presented. A working model is sorely needed.

The project started in 1994 but achievement of results is not clear. A synthesis of results or reference to peer reviewed publications is needed for ISRP review. Most of the results that have been published are in the grey literature, and those that are in journals do not deal with the key results documenting how the fish community has responded and on what scale has the response been observed.

The sponsors state that a report is currently in progress that will update and combine previous reports from 2009 and 2010 with recent data. It would be useful for the ISRP to see this draft

It would be helpful to have more information on the migratory traits of rainbow trout, the apparent target species, as this has a bearing on how far afield nutrient addition effects are projected. Results to date show growth of RBT, as reflected by condition factor, is only being influenced in the nutrient addition reach shown in Figure 22. However the significant increase in whitefish populations and growth of their younger ages is noteworthy. It might be worthwhile to investigate the role of whitefish in the food web of the Kootenai River in some detail. This might involve more collaboration between this project and 199806500 Kootenai River Fishery Investigations. Are whitefish a forage fish for white sturgeon?

Further documentation on lessons learned relative to this aspect from other systems would be instructive. For example, a case history on a fertilization project on the much smaller Keogh and Salmon Rivers in BC showed that the effective distance of fish growth resulting from nutrient additions was on average 15 km (Slaney et al 2003). The furthest downstream monitoring station on the Kootenai seems to be 40 km. Do the sponsors anticipate fish enhancement over these 40 km? What is the role of nutrient spiraling in this regard? The concept is not mentioned in the proposal.

Responses to Past ISRP Comments: The reports being prepared for publication were not provided. At a minimum, there should be a Table with the publication title, key authors, target journal, and submission date.

Adaptive Management: The process is adequate, for the most part, but lacks a guiding model and criteria for change. How are decision-makers incorporated so as to make large scale changes happen?

The ISRP’s Retrospective Report 2011 includes a recommendation on time frame for evaluating restoration projects (p. 68) which is very relevant:

“The ISRP therefore suggests that additional dialogue is needed between habitat managers, scientists, and policy-makers so that realistic timeframes can be established, and appropriate schedules agreed upon, to monitor and evaluate different types of restoration actions.”

Given that this project has been underway for 11 years, it is likely the additional dialogue is required soon.

3. Project Relationships, Emerging Limiting Factors, and Tailored Questions for Type of Work (hatchery, RME, tagging)

See above for comments on project relationships.

RME has been underway for several years, and according to the proposal an adaptive management approach reduced the number of treated sites by 50% without losing significant statistical power or representation. This assertion should be documented.

Emerging Limiting Factors:Climate and land use changes are superficially treated. There are numerous changes taking place and emerging at the local scale. The ISRP urges the sponsors to take these seriously by incorporating them into some of their planning and activities.

4. Deliverables, Work Elements, Metrics, and Methods

Deliverables and work elements generally appear to be appropriate for the project objectives. It appears that the nutrient application process, monitoring methods, and experimental design that have been used in the past will continue with this new project. However, this is not explicitly indicated in the proposal and very few details are provided about the monitoring effort going forward. This point should be clarified.

Restoring the Kootenai River and the Lower Kootenai Watershed to Pre-Impoundment Productivity Levels: The sponsors need to be specific about whether a food web analysis will be performed, how detailed it will be, and articulate how the results will be used to improve productivity. Although positive results have been obtained locally in terms of increasing trout biomass, although not to a statistically significant level, nutrients will need to be applied broadly to significantly improve total trout abundance and growth.

Work Elements: Considering all the work completed to date, is there an overriding model being developed that guides the research and restoration activities? If not, there should be as well as a peer-reviewed synthesis of the progress to date. Further, while the goals are well-articulated, when will they be achieved? A time line is needed for each objective.

Key Personnel: The sponsors have a good level of competence. Two items of concern are the heavy reliance on private consulting firms to do the work and the lack of publications in the peer-reviewed literature. The benefits from this project would increase if central personnel made peer-reviewed publications a priority. While reports are necessary, they are not sufficient for a program of this scope and importance.

4a. Specific comments on protocols and methods described in MonitoringMethods.org

Monitoring has been a major component of this study and needs to continue to be the focus with the implementation of this new phase of this effort. As noted for the Deliverables and Work Elements, the proposal implies that the methods to be used will be those that have been employed in the past. But the proposal does not indicate that this will be the case. If there are any changes in sampling or project design, these changes should have been fully described in the proposal.

Some of the protocols related to environmental and physiochemical sampling are not complete on the website, thereby making it difficult to evaluate. These need to be completed in the very near future.

  • Proponent Response (3/7/2012)
Proponent Response:

The following information is the Kootenai Tribe's responses to the ISRP's project solicitation questions received on 8 February 2012.  

 Responses are requested on the following items:

  1. The sponsors state that a report “currently in progress, will update and combine previous reports from 2009 and 2010 with recent data covering water quality, algae, macroinvertebrates and fish. Reports will emphasize pre-nutrient and post nutrient addition periods (2003-2010). Findings, thus far, have continued to strongly support the positive benefits of nutrient addition to the Kootenai River biota (Holderman and Gidley 2011, In Prep.). Significant increases in primary, secondary, and tertiary productivity levels have been demonstrated.” The ISRP would like to see the latest draft of the report.

Response: The latest draft of the nutrient addition summary report (Holderman and Gidley 2011, editors.Characterization of water quality and the algal, macroinvertebrate, and fish communities in the Kootenai River before and after large scale experimental nutrient addition, 2003-2010. Technical report for the Bonneville Power Administration) can be found at the Tribal fish and wildlife website:  http://www.restoringthekootenai.org/ResourcesKootenai/OnlineLibrary/nutrientlibrary/

2. If tributaries are being used by rainbow trout in the Canyon reach what evidence exists that habitat conditions are limiting there as well as in the main river where the nutrients are being added?

Response: The Idaho Department of Fish and Game (IDFG) have done extensive research on rainbow trout in the Idaho portion of the Kootenai basin during the past several decades (see IDFG project proposal 1988-065-00). Based on telemetry studies, rainbow trout in the Kootenai River exhibit two life histories strategies (adfluvial and resident).  An adfluvial life history is exhibited by rainbow stock from Kootenay Lake that migrates upstream to spawn in the lower Kootenai River (below Bonners Ferry, primarily in the Deep Creek drainage) in Idaho.  The resident life history form remains largely in the main stem Kootenai River, making spawning movements into tributaries that are primarily in Montana (Paragamian and Walters 2010). The adfluvial fish are more likely to benefit from nutrient additions to Kootenay Lake, while the main stem resident trout are the target beneficiaries of additions occurring in the Kootenai River.  

Rainbow trout spawning habitat in the Idaho canyon portion of the river reach is quite limited.  The few tributaries in this reach offer little habitat due to steep gradients and a lack of connectivity to the main channel.  Several tributaries pass through culverts under railroad tracks.  These culverts are often impassable.  In addition, with a lack of flushing flows in the main stem following impoundment by Libby Dam, alluvial fans have developed in the mouths of several tributaries, where flow becomes subterranean during certain times of the year. Water quality sampling was conducted in Boulder Creek in 2004.  Both nitrogen and phosphorus concentrations appeared to be adequate for food web development and productivity though the scope of the study was not extensive.  This may be the case in other tributaries in the reach, but it is not a certainty.  The sponsors recognize that nutrient limitation and habitat availability in the tributaries is a good question and will consider further sampling to address the issue.

The IDFG proposal for project 1988-065-00 details improving rainbow trout growth and densities by determining which tributaries fish are spawning in, how long they are rearing, and whether habitat improvements could aid in providing additional recruitment.  Improved physical habitat conditions and food availability in the main stem likely have improved survival and growth as evidenced by increases in numbers and condition at annual biomonitoring locations in the nutrient addition reaches (Gidley 2010; Holderman et al. 2010; Shafii et al. 2010).

 (Repsonses 2b and 2c below are directed at ISRP comments imbedded within the proposal that project sponsors felt they should clarify.)

 2b. Although this is an interesting experiment and the results are potentially useful, the ISRP concludes that the nutrient addition may not be feasible to maintain over the long term. In other words, nutrient addition is likely not a sustainable method of ecosystem recovery.

Response:  The ISRP may have the impression that nutrient addition is perhaps only marginally benefical. We would like to remind the ISRP of the many significant increases in post-treatment biological and chemical responses among all trophic levels. A brief summary is provided below to substantiate the ecological values of the nutrient addition program.

Following treatment, consistent, significant (P<0.05) increases were observed in nitrogen (NO2 + NO3, TN) and phosphorus (TDP and TP) concentrations, along with non-significant increases in soluble reactive phoshorus (SRP). A significant reduction in TN/TP ratio values also occurred, indicating improvement to the severe phosphorus limitation created by Libby Dam hydro-operations over the last forty years (Holderman et al. 2009a; Hoyle et al. 2011).  Primary productivity has significantly increased (upwards of 10 times on average from pre-treatment levels) and the relative abundance of edible diatoms and green algae has increased, while significant decreases in the relative abundance of inedible Cyanobacteria (blue-green algae) occurred following nutrient addition (Hoyle et al. 2011). Chlorophyll metric responses remain significantly evaluated even into the meander reach (>40 km down river), although benthic invertebrates have not significantly increased in that section of the river following nutrient addition (Kruse et al. 2011; Holderman et al. 2009b;).

Upriver, within the nutrient addition zone (1-40 km’s), the benthic macroinvertebrate community has shown consistent significant increases in overall species richness. Further the mayfly, stonefly, caddissfly group, plus chironomidae (EPT-C) have demonstrated significant increases in abundance, biomass, and taxa richness following nutrient addition (Holderman et al. 2009b). These responses are biologically significant as EPT and chironomid  invertebrate taxa represent  major fish food components in the invertebrate community. Mountain whitefish diet results collected by this project have shown a large increase in benthic invertebrate content consistent with bottom up trophic enhancement (unpublished KTOI-IDFG data).

Within the fish community mountain whitefish abundance, biomass, and mean length at age for several juvenile age classes increased significantly following treatment (Gidley 2010; Holderman et al. 2010; Shafii et al. 2010; Holderman and Gidley 2011). Adult kokanee salmon returns to multiple spawning tributaries in the meander reach have increased by 2-3 orders of magnitude following nutrient addition (Ericksen et al. 2009; unpublished KTOI data 2011), which is likely due to the synergistic interaction of nutrient additions to Kootenay Lake and the Kootenai River, and ongoing tributary restoration efforts by the Tribe which includes annual kokanee egg plantings. Finally, in addition to the suite of significant, positive treatment effects across trophic levels, no adverse or undesirable treatment effects have been  observed during the nutrient addition period (7 years ongoing), as demonstrated  by overwhelmingly positive metric responses in  water chemistry, and, the algal, macroinvertebrate and fish communities (Holderman and Gidley 2011; Hoyle et al. 2011). The only slightly negative result is that the currently level of phosphorus being added may not be enough to fully mitigate for lost productivity within the Idaho river reaches. Additional nutrient addition sites, increases in the application season timeframe and nutrient concentration, and wetland restorations will likely be need in the future to fully mitigate for the phosphorus, nitrogen and related organic matter currently lost to hydro operations at Libby Dam.

The ISRP comment suggesting that “nutrient addition is likely not a sustainable method of ecosystem recovery” is surprising to project sponsors, given the limited number of options available for ecosystem restoration of a significantly denutrified system, caused largely by the development of the federal hydropower system. The total cost of nutrients lost behind Libby dam on a yearly basis is likely far greater than the annual nutrient replacement costs currently incurred by this project. Moreover, this doesn’t include the 35 or so years of unmitigated nutrient losses created by Libby Dam hydro operations prior to nutrient additions.

The Tribe understands the complexity of ecological processes, and by association, of ecosystem restoration of those processes. Based on this recognition, the Tribe has developed and implemented a coordinated array of physical habitat, nutrient, and interim (hatchery) fish population restoration projects designed to restore the Kootenai River’s biological productivity and ecological functions. However, Libby Dam continues to severely alter and limit the conditions of the river downstream, negatively affecting the hydrology, hydraulics, habitat formation processes, water chemistry, sediment and large woody debris loads, plus thermal conditions important to river biota. The river has also lost over 50,000 acres of its natural floodplain and the associated annual spring flooding that occurred due to the combined effects of hydro operations and extensive diking. The combination of wetlands and periodic flooding was likely extremely important to biological productivity and habitat diversity in the lower river-floodplain ecosystem that historically existed from Bonners Ferry to Kootenay Lake. The Tribe’s conservation hatchery program is currently operating as an interim life support system for several key native fish species that would otherwise go extinct prior to completion of the physical habitat restoration needed to restore natural production.  Most importantly, none of these other restoration options (physical habitat restoration and the native fishes conservation aquaculture program, or lower river wetland restoration) can directly address and mitigate the ongoing denutrification of the river downstream from Libby Dam.

2c. A concern about this objective relates to river fertilization for salmonids. While it seems to be working within a limited section, are the costs and logistics of expanding this treatment elsewhere in the river feasible.

(Firstly the tribe would like to mention that we envision nutrient restoration, first and foremost, as a needed restoration component for the entire ecosystem  (including riparian and terrestrial communities), not just a particular species or guild of species.)

Response: While project proponents appreciate the need to evaluate the cost effectiveness and cost-benefit ratios of large restoration projects, comparisons of this project to river fertilization projects for salmonids could set an inappropriate precedent for this project and for other nutrient addition projects in the upstream blocked areas (those areas upstream from dams that prohibit upstream anadromous fish passage). Unlike the potentially restorable cycle of marine derived nutrients (MDN) in anadromous salmon systems, the presence and operation of dams in blocked areas are continuous and ongoing sources of nutrient limitation that cannot be mitigated by restored MDN loadings. In restored or functional salmonid systems, marine derived nutrients naturally play a major role in restoring nutrient concentrations in natal areas. Alternatively, the presence of dams in non-anadromous regions upstream from marine nutrient contributing species presents a potentially chronic nutrient shortage, especially if the river is at or near an oligotrophic condition prior to impoundment. This is the current situation that exists on the Kootenai River below Libby Dam. Thus river managers are left with very few options to restore nutrients and productivity to the Kootenai River. Finally, nutrient restoration is a key under pinning of other restorative projects (e.g. physical habitat restoration efforts) and conservation aquaculture programs within the basin.

In terms of cost and logistics of potential project expansion, early feasibility investigations for this project suggested  direct biological benefits would occur up to 30-40 km downstream from the nutrient addition site, given  in-river target phosphorus concentration (3 µg/L TDP) (see also reply to ISRP Item 3 below).  As noted by the ISRP in other comments regarding this project, the Kootenay Lake North and South Arm fertilization programs, partially funded by this project, have been a very successful fisheries restoration tool (Ashley et al. 1997; 1999; Schindler et al. 2011). Furthermore, the treated river reach from the Montana-Idaho border downstream to the meander reach at Bonners Ferry is consistently showing desirable biological responses across trophic levels, with decreasing response magnitude further downstream from the nutrient addition site. The meander reach from Bonners Ferry downstream to Kootenay Lake is a heterotrophic reach (compared to autotrophy in the upstream braided and canyon reaches) which complicates the direct application of nutrients  (please also see response to ISRP item 3 regarding details of longitudinal patterns of  response to nutrient addition). Thus, future expansion of the project treatment area could be considered upstream in Montana, but would have to be evaluated and negotiated with relevant managing agencies in that state.

In summary, ongoing nutrient addition to the Kootenai River represents the most direct and logical form of mitigation until nutrient losses and limitations from Libby Dam are no longer in place. The ISRP suggestion that nutrient addition program may not be ecologically sustainable in the long term, and by implication should cease and desist, could lessen the successes of the other Kootenai River ecosystem-based restoration projects currently underway and planned for. We strongly believe the restoration of physical habitat, nutrients, and genetically viable fish populations as three irreplaceable components of ecosystem restoration until the limitations from regulated flow are no longer present.

3. How far downstream are the nutrient benefits expected to be realized?

Response: Early feasibility investigations based on research from British Columbia, Canada,  suggested  direct biological benefits would occur up to 30-40 km downstream from the nutrient addition site, given the target in-river phosphorus concentration of approximately 3 µg/L total dissolved phosphorus (Ken Ashley, Northwest Hydraulic Consultants, Vancouver B.C., personal communication). Monitoring evaluations by this project have confirmed this prediction, providing supporting biological evidence from every trophic level (Holderman and Gidley 2011). Some positive biological responses among trophic levels, such as elevated chlorophyll a, are also evident further downstream in the meander reach. However, response magnitudes are progressively smaller further downstream, with the exception of population responses from migratory fish species like kokanee, which experienced significant escapement increases (<100 fish to 800-1000 per year) following treatment in multiple meander reach tributaries (Ericksen et al. 2009). Detailed summaries of these findings by trophic level are provided in all completed trophic level project reports (Ericksen et al. 2009; Holderman et al. 2009a, 2009b, 2009c, 2010a, 2010b; Kruse et al. 2011) and have largely been updated with data through 2010 and will be reported on further during 2012.

One trophic level example includes overall (all taxa) invertebrate biomass and richness, and Ephemeropter Plecoptera and Trichoptera (EPT) abundance, biomass, and richness. All these metrics increased significantly (P<0.05) following nutrient addition in the nutrient addition zone (1-40 km downstream) (Holderman et al. 2009). Consistent with this trend, notable increases in these metric values were observed in the canyon and braided reaches downstream from the nutrient addition site (KR9.1) to KR-6 in the braided reach (See figures 3.1-3.4  below; nutrient addition began in 2005; nutrients are added  near KR9.1; upstream is to the right on the plots).

A second example of the longitudinal extent of biological benefits from this project involves mountain whitefish abundance, which increased significantly in the nutrient addition zone following treatment (P=0.010; Holderman et al. 2010). Following nutrient addition, mean abundance of mountain whitefish (number of fish/hr of electrofishing) more than doubled from 198.2 to 441.5 at KR9, and increased by nearly 75% (from 247.1 to 429.2) at KR6 (See figure 3.5 below). The braided reach extends about 6km upstream and downstream from KR6.

 3b. Will these benefits interact with the bioengineering work being done in the braided reach?

Response:  Yes, biological benefits from nutrient addition are expected to interact positively with the bioengineering work being done in the braided reach. Nutrient addition occurs at the Idaho-Montana border (rkm 276), with direct effects measurable downstream to Bonners Ferry (rkm 246) and beyond into the meander reach.The braided reach is located between rkm 246 and 258, in the lower end of the zone of biological response. The 17km reach from KR9.1 (rkm 267.1) to KR6 (250.0) is consistently referred to in all trophic level project reports as the zone of biological response or nutrient addition zone, based on the spatial distribution of biological responses. Site KR6 is located in the brained reach just downstream from the initial habitat restoration bioengineering work completed during 2011. This site, prior to any habitat restoration, showed a strong response in algal, macroinvertebrate, and whitefish productivity since nutrient addition started in 2005 (Holderman and Gidley 2011). Further increases in biological benefits are expected after the habitat projects are fully established.

3c. Do the sponsors anticipate a nutrient spiraling effect?

Response: Yes, project sponsors anticipate a nutrient spiraling effect. We feel nutrient spiraling will, over time, spatially   distribute nutrients (in organic and inorganic forms) to lower river reaches. Further, the nutrient additions to the south arm of Kootenay Lake are designed  to increase fish population that migrate to Idaho during parts of their life cycles, thus returning nutrients to the river and tributaries from downstream. This could be viewed as nutrient spiraling in reverse order, that is, back upstream from the lake to areas of critical need in the ecosystem (in marine systems referred to as a “nutrient pump”). For example, kokanee salmon that are currently benefitting from nutrient additions to Kootenay Lake are returning as adults to several Kootenai River streams to spawn. After spawning, their carcasses are deposited in these lower river tributaries providing key nutrients (please do not confuse kokanee spawning streams with tributaries in the Canyon reach discussed above. Kootenai River kokanee spawning streams for the most part drain the granitic-based Selkirk Mountains and are very oligotrophic in nature (Erickson et al. 2009; Kruse  2007)). Additionally, the Tribe believes that over time unused annual benthic algae organic matter from the autotrophic reaches of the Kootenai River will spiral into the lower river reaches building food stores that will benefit heterotrophic benthic insect community that exists there.  Finally, the Tribe and IDFG initiated a nutrient consumption study during 2011 to better understand how nutrients are used and to what degree over the course of the 30-40 km autotrophic zone. Information obtained in this study will provide empirical information concerning the spiraling aspects of nutrient addition in the Kootenai River.

                4a. Is there a working model that sets the nutrient addition response in the context of the whole ecosystem? If so ISRP would like to see details on the model.

Response: Unfortunately, we do not have a working model that sets the nutrient response in the context of the whole ecosystem.  The Tribe, IDFG and other co-managers participated in a modeling -based workshop exercise called Adaptive Environmental  Assessment during the early formation of this project (1990’s), initially to assist with analysis of operational effects of Libby Dam on fisheries recovery efforts. The process was called Adaptive Environmental Assessment (AEA) and the workshop leader, Dr. Carl Walters, determined that the primary objective for developing the model would not be to create a simulation program that permitted detailed quantitative predictions about the effects of changes in management of Libby Dam, but one that could potentially help define and prioritize research programs and experimental design. Walters and Korman (1998) developed the Adaptive Management Kootenai River Simulation Model User’s Guide (www.restoringthekootenai.org/ResourcesKootenai/OnlineLibrary/nutrientlibrary/).  However the exercise was held back by a lack of substantial and accurate trophic level data for the Kootenai River. The modeling exercise was useful in terms of exposing the broad gaps in data and understanding that these can be easy to overlook in verbal and qualitative assessments. The effort did highlight the need for better water quality and underlying trophic level information that this project took seriously. Tribal management decided that our focus should turn to biomonitoring and research to obtain better information for fisheries restoration activities, one of which was the possibility of nutrient limitation to food web development. After several years of monitoring and research the Tribe, IDFG and the British Columbia Ministry of Environment concluded that nutrients were a limiting factor to fisheries. This led to project implementation of the dual nutrient addition efforts on the river and Kootenay Lake in 2004. At the same time, at the request of the Tribe and other managers, another modeling workshop was convened and was led by Dr. Carl Walters. Dr. Walters, and others experts, advised the Tribe and IDFG that further modeling would likely be a misuse of resources until substantial data was obtained from the nutrient addition projects. Then, at that point, it would be useful to pursue further model development exercises as part of a larger adaptive management review process for the nutrient addition efforts.

In summary, project sponsors recognize that further modeling would likely benefit the project’s activities. We also recognize these efforts can be laborious and expensive at a time when the project’s dollars are stretched fairly thin. Nonetheless the Tribe is considering future modeling as part of the adaptive management exercise for evaluation of this project’s effectiveness. 

                 4b. Will the annual cost of $1.8 M be ongoing?

Response:  Yes, ongoing cost of 1.8 M is the base level needed to maintain nutrient addition efforts (lake and river) and associated monitoring, data management/analyses and reporting of those activities. This also includes cost of basin-wide monitoring covering regulated section of river, and one un-regulated control station as comparison locations for regulated reaches and nutrient addition activities, and small scale research activities related to nutrient additions.

5. Whitefish seem to be responding to nutrient addition. What is their role in Kootenai River food web and could they be a food item for sturgeon?

Response:  Mountain whitefish have a strong preference for benthic aquatic insects  in the Kootenai River food web and are responding very well to increased invertebrate abundance (KTOI unpublished whitefish diet data; Holderman et al. 2009; Gidley 2010; Shafii et al. 2010). One role of mountain whitefish in the Kootenai River food web may be to link enhanced benthic invertebrate  productivity to the fish community, while potentially serving as prey for apex predators in the system, such as mature white sturgeon and bull trout. Thus, a general argument could be made that increased forage fish (whitefish, suckers, and others) abundance and biomass in the system will likely support larger piscivorous predators as the benefits of nutrients are realized.    

Therefore, mountain whitefish could certainly be a sturgeon prey item. However, the current degree of habitat overlap between the two species may be relatively low. The significant post-treatment increases in whitefish abundance and biomass have been observed in the braided and canyon reaches whereas the majority of adult sturgeon occupy the meander reach and Kootenay Lake. Whitefish are rare in the meander reach habitats in the Kootenai River (Gidley 2010; Holderman and Gidley 2011; IDFG project proposal 1988 -065-00). However, recent recoveries of increased numbers of hatchery-produced juvenile sturgeon upstream from Bonners Ferry and in Montana waters of the Kootenai River following nutrient addition are encouraging, and suggests that sturgeon may be taking advantage of increased abundance of whitefish and other vertebrate and invertebrate prey items following nutrient addition (Shafii et al. 2010). This may be particularly important given the increasing abundance of juvenile whitefish that could serve as a valuable food source for sturgeon and other piscivores. Although little sturgeon stomach content data are currently available from the braided and canyon reaches, collection of such samples could be proposed in response to this ISRP question to assess potential contributions of the nutrient addition program to sturgeon.

6. Reports being prepared for publication were not provided although requested at the last ISRP review. At a minimum, the sponsors should provide a Table with the publication title, key authors, target journal, and submission date. 

Response:  In response to this ISRP request, we provide the following tables of completed and anticipated manuscripts and reports for the Kootenai River Ecosystem Improvement Project (BPA 199404900). This table includes publications since the last project proposal renewal, encompassing years 2009-2012 and their individual document web link address. No official group decisions regarding possible journals for this venture have been made at this time. However, the topic continues to be discussed regularly among the IKERT members (International Kootenai/y Ecosystem Restoration Team).  Project sponsors will update the list as additional progress is made.

7.  If changes in the monitoring protocols are anticipated in the future the ISRP would like a description of them.

Response:  There are currently no anticipated changes to the monitoring method or protocols as listed on the Monitoring Method website (www.monitoringmethods.org). However, the project conducts regular reviews and evaluations of all trophic level and water quality monitoring data regarding site retention, sample size determination, sampling frequency, and statistical power analyses to insure adequate scientific representation at reasonable costs. This will allow the project to reallocate resources and distribute funds to other areas of need.

For example, in 2010, after a series of technical discussions, and following targeted statistical evaluations, the project personnel decided to drop four of the monitoring sites. These included sites KR3, KR7, KR11, and KR12. The decision was made primarily due to the constant rate of response in primary and secondary production, and redundancy observed between these and the other adjacent sites. To ensure continuity, however, it was further decided that the aforementioned sites will be revisited/sampled in the future on a longer periodic time horizon (3-5 years) to provide a more informative and robust picture of the Kootenai River aquatic ecosystem.

Several sampling strategies were also modified starting with the 2010 bio-monitoring season. These included dropping monthly metals sampling across the basin from the water quality protocol (due to lack of measureable responses), dropping water chlorophyll from the primary productivity protocol (due to redundancy: tile chlorophyll responses were highly correlated with water chlorophyll responses analyzed over several years), changing the taxonomic resolution for algae from species to division level (due to observed lack of discernible patterns in lower taxonomic groups), and collecting 5 macroinvertebrate samples per bio-monitoring season instead of 6 as in previous years (following sample size determination and cost analyses).


In 2010, based on 5 years of small and large scale monitoring results, the Kootenai Tribe and Idaho Department of Fish and Game, with input from other members of IKERT, proposed to increase the phosphorus loading concentration from the current level (3 ug/l) to 5 ug/l. Additionally, the project sponsors proposed to lengthen the nutrient addition period from the current period of 120 days (1 June to 30 September) to approximately 220 days (15 March to 31 October) annually. While it is likely that nutrients would not be added during the entire period, this new monitoring schedule would allow for more flexibility by project managers to mimic natural conditions that existed prior to Libby Dam and regulated river flows. For instance, a robust period of algae growth occurs in the early spring in most natural, unregulated rocky mountain rivers, starting around the spring equinox and proceeding until the first substantial snowmelt occurs (typically May). Furthermore, Libby Dam reduces downstream nutrient delivery year-round, and longer addition periods would better mitigate these losses.

Project managers have observed and collected empirical data in support of increased primary production within the upstream unregulated reach of the Kootenai River in British Columbia, Canada in the early spring prior to the annual freshet (Holderman et al. 2009). This early season algal productivity is likely very important for aquatic invertebrates that have over-wintered in various life stages and are preparing to complete their life-cycles during the upcoming growing season.  Currently, within the regulated portion of the Kootenai River, and particularly in the Idaho canyon reach, very little algae growth is observed during the spring period. Adding nutrients at an earlier time than allowed by the current permit would likely benefit aquatic invertebrate survival and reproductive abilities, which would ultimately enhance fisheries. Additionally, increasing the dosage concentration to 5 ug/l would likely extend these benefits further downriver than currently observed. Trophic level data within the nutrient addition zone are showing a decline in the effect of nutrient addition in the Kootenai River after 30-40 kilometers using a phosphorus concentration of 3 ug/l (also refer to project sponsors reply to ISRP item 3 above).

10.  More details are required on the particular relationships, at the working scientific level, between this project and the other three Kootenai River proposals.

Response: (The following is a jointly prepared document for the Kootenai River projects currently under review).

The ISRP commented that the connections between the three Kootenai Tribe projects, and the Idaho Department of Fish and Game’s (IDFG) Kootenai River Resident Fish Mitigation project (198806500), presented as part of the resident fish, data management, and regional coordination category review, were not adequately described in any of the four proposals.  We acknowledge that this was a weakness in our collective proposals and appreciate the opportunity to better explain the relationships between these projects. In reading through the ISRP comments on each of the four project proposals we also recognized that a more thorough explanation of the various advisory groups associated with the Tribe’s projects would also assist the ISRP in better understanding the individual projects, relationship between projects, and the Tribe’s Program as a whole. 

Towards this end the following response includes: 1) an overview of the context for the Tribe’s Fish and Wildlife Program; 2) the history of the Kootenai Tribe’s Fish and Wildlife Program; 3) a summary of the relationship of three Kootenai Tribe projects included in Resident Fish, Data Management, and Regional Coordination Category Review and IDFG’s project 198806500; 4) additional information regarding the advisory and coordination groups used to inform the Tribe’s projects; and 5) additional information regarding the subbasin-scale adaptive management plan that the Tribe is currently developing.

In many of the Tribe’s proposals mention is made of the Kootenai people’s creation story and commitment to the long-term guardianship of the land.  It can sometimes be difficult not to gloss over such statements as mere platitudes.  However, the commitment outlined in the Kootenai Tribe’s creation story is a very real and living commitment and represents the foundation from which all of the Tribe’s Fish and Wildlife Program activities emerge.

Specifically, Kootenai Tribe elders pass down the history of the beginning of time, which tells that the Kootenai people were created by Quilxka Nupika, the supreme being, and placed on earth to keep the Creator-Spirit’s Covenant – to guard and keep the land forever.  The Kootenais have never lost sight of their original purpose as guardians of the land and the Tribe’s efforts today are a reflection of this commitment.

1.  Context for the Kootenai Tribe’s Fish and Wildlife Program

As described with varying emphasis in each of the Tribe’s project proposals, over the course of the last century the Kootenai subbasin has been extensively modified by agriculture, logging, mining, and flood control.  To protect and extend agricultural and development, levees were constructed on top of natural sand levees for flood control starting in the 1900s, reducing the hydrologic connection between the Kootenai River and its floodplain.  However, without river regulation this levee system failed, or was occasionally overtopped.  The Kootenai River was confined by the construction of Libby Dam in Montana, which created Koocanusa Reservoir, and Corra Linn Dam downstream in British Columbia, which impounds Kootenay Lake.  Over 50,000 acres of historically highly productive floodplain were converted to agricultural fields, resulting in the loss of riparian and wetland plant and animal species, and the related functions that normally support a healthy ecosystem (EPA 2004).  In 1972 Libby Dam became operational, effectively reducing annual peak flows by half and disrupting the hydrograph, which historically featured a single spring freshet that provided energy to drive ecosystem processes.  These modifications resulted in unnatural flow fluctuations and changes to the temperature regime in the Kootenai River and its floodplain, which exacerbated the effects of previous anthropogenic impacts.  Construction of Libby Dam (in concert with extensive diking) also resulted in a major loss of nutrient inputs to the Kootenai River. Cumulatively, these impacts have resulted in depressed biological system productivity, altered community structure and species composition across trophic levels, and loss of floodplain and riparian function. 

The Kootenai Tribe traditionally depended on the vast aquatic and terrestrial resources of the Kootenai River subbasin and other neighboring areas (i.e., Clark Fork, Pend Oreille and the upper mainstem of the Columbia and Kootenai rivers) for subsistence and ceremonial purposes.  A natural fish passage blockage at Bonnington Falls prevented anadromous fish from entering the Kootenai River.  However, the Tribe often traveled to salmon fishing areas within the Columbia River drainage in order to take advantage of the large salmon runs in the fall of the year.  The Tribe traditionally relied upon the Kootenai River basin’s resident fish year round.  “Their chief articles of food are roots and fish.  The waters of the Kootenai River afford them at all seasons an abundant supply of salmon-trout,” reported Lt. John Mullan (1885).  Schaeffer (1940) reported “the Kutenai fished for ling in the fall/winter months using weirs constructed on tributaries of the Kootenai River”. 

While the Tribe relied on roots and fish for their main sources of food (Mullan 1885), terrestrial game and other vegetative resources were also very important for food, medicinal, spiritual and ceremonial purposes.  In addition to fish, ducks were taken in great numbers and were a staple for the Kootenai people (Turney-High 1941).  Duck netting was a communal activity with the supervision of a Duck Chief. Other waterfowl were cherished, such as geese, but these were taken by means of bow and arrow (Turney-High 1941).  Historically nearly 22,000 acres of wetland habitat were maintained by flooding river conditions throughout the Idaho portion of the lower Kootenai Valley (EPA 2004).  This large wetland area incorporated high level of energy and nutrient exchanges within the ecosystem.  Waterfowl breeding and molting seasons corresponded to flooding and subsequent wetland filling.  Avian predators once thrived in the area as well as a result of excellent habitat conditions and thriving aquatic communities.  Intact riparian areas with mature cottonwood stands contributed to provide nesting and perching habitats.

The upland terrestrial habitat supported mammals such as white tailed deer, moose, elk, woodland caribou, mule deer, and mountain goat.  Woodland caribou were an abundant resource in the Kootenai (Turney-High 1941).  The aquatic and terrestrial components of the Kootenai River ecosystem supported mammalian predators such as grizzly bears, lynx, red fox, coyote, gray wolves, cougars, fisher, river otters, mink, bobcat and black bears.

Today the ability of the Tribe to exercise Treaty-reserved fishing rights and to engage in subsistence and cultural uses of aquatic and terrestrial resources is significantly curtailed.  The local community has also suffered from the losses of diversity of aquatic and terrestrial resources that would otherwise provide an important contribution to the vitality and economic viability of the region. 

2.  Kootenai Tribe Fish and Wildlife Program Overview and History

The Kootenai Tribe’s Fisheries Department was established in 1988 and the Wildlife Division was added in 1999.  The role of the Tribe’s Fish and Wildlife Program is to work towards restoration of the Kootenai River ecosystem and implement restoration and mitigation actions that will help achieve the Tribe’s vision of:

The Kootenai River and its floodplain as a healthy ecosystem with clean, connected terrestrial and aquatic habitats, which fully support traditional Tribal uses and other important societal uses. 

An additional component of the Tribe’s overarching vision for the Kootenai River subbasin recognizes that:

A healthy ecosystem reflects and promotes the cultural values and long-term sustainability of present and future generations.

The Tribe recognizes that implementation of this vision needs to occur within the context of a sustainable local community and economy.  In support of this approach Tribe is committed to developing and implementing innovative and collaborative approaches to shared guardianship of the land – an approach that is reflected throughout the Tribe’s Fish and Wildlife Program.  As part of their Fish and Wildlife Program activities the Kootenai Tribe also seeks specifically to restore their ability to exercise Treaty-reserved fishing rights and to assist the federal (U.S.) government in fulfilling its Tribal Trust responsibilities. 

From the outset the Tribe’s Fish and Wildlife Program has been structured around five core guiding principles: 

  • Science-based
  • Holistic
  • Collaborative
  • Consistent with Tribal cultural values
  • Inclusive of local social and economic values
  • Adaptively managed

The Tribe’s Fish and Wildlife Program grew initially out of the urgent need to address the precipitously declining Kootenai river white sturgeon population.  The Tribe’s Fisheries Department implemented the first Tribal fish and wildlife project in 1988 that included sampling of the white sturgeon population in the Kootenai River and the construction of an experimental Kootenai Sturgeon hatchery in 1991 (project 198806400).  During the late 1990s and early 2000s the impacts of declining fish populations were highlighted by a series of listing decisions and petitions to list species including Kootenai River white sturgeon (listed 1994), bull trout (listed 1998), burbot (petitioned 2000), and westslope cutthroat (petitioned 1998). 

By 1994 the Tribe and partner agencies in the Kootenai Subbasin were beginning to look beyond single species fisheries management projects and thinking about developing a more comprehensive ecosystem-based approach to investigating, identifying and addressing factors underlying the decline of native fish populations in the Kootenai subbasin.  The Kootenai River Ecosystem Restoration project (199404900), also known as the nutrient project, was started in 1994.  The project was initially an offshoot from the Tribe’s Conservation Aquaculture program (198806400), and focused on an ecosystem approach to addressing aquatic bioenergetic trophic levels and water chemistry to support fish life.  The nutrient project marked a fundamental shift in thinking at the time, from a belief that fish population declines were a stand-alone problem to be addressed, to a recognition that fish population declines were in fact symptoms of underlying ecological limitations and imbalances that needed to be addressed.  

In 1999 the Tribe added a wildlife division to the existing fisheries department and the full Kootenai Tribe Fish and Wildlife Program was created.  The Tribe’s wildlife division was added when the Tribe was incorporated into the Albeni Falls Wildlife Mitigation Project (199206105) in 1999 (although the Albeni Falls project began formally in 1992).  Inclusion in this project represented the first opportunity for the Tribe to address mitigation for wildlife losses associated with construction, inundation and operation of Albeni Falls Dam (operational losses associated with Albeni Falls Dam have not been addressed yet) and subsequently operation of Libby Dam.

The Lower Kootenai Model Watershed Restoration Project began in 2000 as a request from a landowner for help with habitat restoration work to return historical fish populations to Trout Creek, a west-side tributary to the Kootenai River.  The Tribe sought funding from Bonneville Environmental Foundation (BEF) and secured a ten-year Model Watershed restoration grant to fund a restoration and monitoring program in Trout and Long Canyon Creeks beginning in 2003 (Kruse 2007).  The majority of restoration actions have now been completed and project monitoring continues under Project 199404900.

In 2002 the Operational Loss Assessment project (project 200201100) and Reconnect project (200200800) were both added as part of the Tribe’s overall wildlife mitigation program.  The NPCC subsequently re-characterized the Reconnect project as a fisheries project and it has been included in resident fish reviews of projects.  However, the Tribe still views the primary focus and purpose of the Reconnect project as being linked to the Operational Loss Assessment and to wildlife mitigation and restoration objectives.

From the mid 1990s through early 2000s a number of regional efforts were initiated in the Kootenai subbasin that ultimately resulted in completion of recovery and/or conservation plans for Kootenai River white sturgeon, Bull Trout and Burbot.  The Kootenai Tribe was an active participant in all of the coordinated planning associated with these efforts.  Collectively these various planning efforts helped to further inform and guide the focus of assessment activities conducted under the Conservation Aquaculture project (project 198806400), Ecosystem Restoration project (project 199404900), and Assess Feasibility of Enhancing White Sturgeon Spawning Substrate Habitat project (project 200200200).

The Tribe’s Fish and Wildlife Program grew initially in response to specific restoration issues and opportunities.  A more explicit identification of the framework within which the Tribe’s individual projects were nested began in 2003 with initiation of the NPCC efforts to develop standardized and collaboratively developed subbasin plans throughout the Columbia River Basin.  The Kootenai Tribe of Idaho and Montana Fish Wildlife and Parks (MFWP) took on a leadership role in this effort, producing the first complete subbasin plan in the Columbia River Basin.

The Kootenai River Subbasin Plan was completed in 2004 (KTOI and MFWP 2004).  The subbasin plan included an assessment of current conditions in the subbasin, and identified a management plan which incorporated a suite of primary and secondary limiting factors and quantifiable goals and objectives.  Figure 1 summarizes the primary and secondary limiting factors.  Figure 2 shows the role each of the Tribe’s projects plays in addressing the primary and secondary limiting factors and actions as identified in the 2004 Kootenai River Subbasin Plan (KTOI and MFWP 2004).  The Kootenai River Subbasin Plan (along with other Columbia River Basin subbasin plans) was subsequently amended into the NPCC Fish and Wildlife Program.

Figure 2.  Summary of relationship of primary and secondary limiting factors, actions (metrics/objectives from subbasin plan) and individual Tribal projects (KTOI & MFWP 2004).   

At the outset, the majority of the Tribe’s Fish and Wildlife Program projects were focused to a large extent on data collection and analysis.  Over the years as data and analysis, and monitoring and evaluation accomplished through the Tribe’s projects and through the projects of other regional partners (e.g., IDFG, MFWP, B.C. Ministry of Forest Land Natural and Resource Operations) and as the overall understanding of the Kootenai River subbasin ecosystem has improved -- the focus of the Tribe’s projects has shifted generally to more targeted feasibility analysis in support of implementation of specific restoration or mitigation actions, and to implementation of those actions.  This focus is reflected in the Tribe’s 2011 proposals. 

Another way to look at the interrelationship of the Kootenai Tribe’s Fish and Wildlife Program projects is related to how the projects address the impacts of climate, wetland disconnection and conversion, and Libby Dam hydrology on abiotic conditions, biotic communities, trophic dynamics, and species and population dynamics.  Table 2 illustrates the role that each of the Tribe’s projects plays in providing data and/or implementing actions related to each of these ecosystem components.

Table 2.  Relationship of Kootenai Tribe projects to Kootenai River ecosystem components.

 image003

As part of the initial work to develop a subbasin-scale adaptive management plan for the Kootenai Tribe’s projects (discussed later) the Tribe identified five draft overarching goals that unite the Tribe’s Fish and Wildlife Program and that are consistent with broader-scale initiatives such as the Kootenai Subbasin Plan and the NPCC Fish and Wildlife Program. 

The five draft goals are to protect, restore and maintain:

  • Food web – As an oligotrophic (low nutrient) and fragmented ecosystem, the Kootenai River and its higher order organisms are likely impacted by a lack of food web support. 
  • Ecological connectivity within Kootenai River subbasin – This includes reconnecting tributaries to the mainstem Kootenai River as well as connecting the mainstem Kootenai River to riparian areas, floodplains, and terrestrial habitats.  This connection is important for nutrient exchange and will increase available habitat diversity and quantity for fish and wildlife.
  • Suitable, self-sustaining or aquatic and terrestrial habitat for fish and wildlife – Habitat is the ecosystem component that can be most directly affected by management actions such as active restoration projects.
  • Biological populations Some species in the Kootenai River ecosystem are either functionally extinct or on the verge of functional extinction. Restoring these populations, and populations of other species they depend on, is important both ecologically and culturally.
  • River physical and chemical processes, and their inherent natural range of variability – Anthropogenic activities have affected the physical and chemical processes in the ecosystem, and understanding these changes is necessary to support management actions that will address them.

All of the Kootenai Tribe projects conduct data collection, analysis or implement actions related to achieving these five goals. 

3.  Relationship of Kootenai Tribe projects included in Resident Fish, Data Management, and Regional Coordination Category Review and relationships to Idaho Department of Fish and Game project 198806500

Three Kootenai Tribe projects were proposed as part of the Resident Fish, Data Management, and Regional Coordination Category Review.  The ISRP requested a clarification of the relationships between those projects: 

  • Kootenai River Ecosystem Restoration (Nutrient Project) (199404900)
  • Reconnect Kootenai River with the Historical Floodplain Project (200200800)
  • Restore Natural Recruitment of Kootenai River White Sturgeon (Kootenai River Habitat Restoration Project) (200200200)

The ISRP also asked for clarification regarding the relationship of the three Tribal projects to the IDFG Fishery Investigations project in the Kootenai subbasin:

  • Kootenai River Fishery Investigations (Kootenai River Resident Fish Mitigation) (198806500)

The short summary to the ISRP question is that:

  • Project 199404900 (Kootenai River Ecosystem Restoration) provides nutrient addition in the Canyon Reach of the Kootenai River and Kootenay Lake in Canada, and aquatic based, trophic-level and water chemistry monitoring of a 235 km reach of the Kootenai River and key tributaries.
  • Project 200200200 (Kootenai River Habitat Restoration Project) is implementing habitat restoration actions (including mainstem, substrate enhancement, off channel, riparian, and floodplain habitats) in the Braided Reaches, Straight Reach and Meander Reaches to address the habitat needs of all life stages of Kootenai sturgeon, burbot, bull trout, kokanee, westslope cutthroat trout, and redband trout and other native fish.
  • Project 200200800 (Reconnect Kootenai River with the Historical Floodplain Project) is implementing habitat restoration to reconnect the Kootenai River with the historical Floodplain as part of wildlife habitat restoration activities associated with both the OpLoss Project and the Albeni Falls Project.  Reconnection projects identified in the 2013-2017 proposal include Ball Creek and Nimz Ranch in the Meander Reach.
  • Project 198806500 (Kootenai River Resident Fish Mitigation) is conducting monitoring and evaluation activities associated with Kootenai sturgeon and burbot that help inform recovery, habitat restoration, Libby Dam operations for sturgeon and burbot, and evaluation and adaptive management in the Kootenai River.  IDFG is also a partner to the Tribe on project 199404900 assisting with implementation of nutrient addition and monitoring the fish community at established monitoring sites throughout the basin.

The following maps are provided to help clarify the physical relationships between the projects and the extent and location of monitoring activities.  Figure 3 shows the locations of project 200200200, 200200800, 199404900 and the IDFG project 198806500 electrofishing, egg mat sites, sturgeon free embryo release sites, and sturgeon and burbot sampling sites from project 198806500.  Figure 4 shows the location of the Kootenai River Ecosystem Restoration project (199404900) course-scale and fine-scale sampling sites.  Figure 5 shows just the location of the IDFG electrofishing, egg mat sites, sturgeon free embryo release sites, and sturgeon and burbot sampling sites from project 198806500 without the other projects.

 In the ISRP comments on the IDFG proposal and on some of the Tribe’s projects, reference was made to the various entities “claiming to coordinate”.  Something that is difficult to convey through the proposal format and to people who aren’t intimately familiar with the work in the subbasin is the extent of day-to-day coordination the occurs among the various management partners throughout the Kootenai subbasin (i.e., Kootenai Tribe, IDFG, MFWP, B.C. Ministry of Forest Land and Natural Resource Operations, U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and Bonneville Power Administration).  We communicate regularly by email and phone, we are in meetings together, we are in workshops together, and we are in the field together on a regular basis.  The level of coordination and integration could certainly always be better but there is an extraordinary effort going into working together and continuing to learn how to work together better.

An additional factor that sometimes confounds full integration of projects is the different and occasionally conflicting organizational missions, goals and objectives among different agencies and between agencies, and the Tribe.  Additionally, the BPA/Northwest Power and Conservation Council’s review and funding process has separated wildlife and resident fish into artificially independent categories, which minimizes and obscures the integration that occurs in the real world projects. 

In the context of this resident fish review, no single action will restore populations of Kootenai sturgeon, burbot, bull trout, or other native fish in the Kootenai River.  No single entity’s actions or project(s) will restore the ecosystem.  The Tribe and other partners in the Kootenai River subbasin work together to use human and fiscal resources as effectively as possible to achieve restoration of the Kootenai River ecosystem.  This effort includes flow and temperature operations at Libby Dam (USACE and BPA in coordination with Kootenai Tribe, MFWP, IDFG and USFWS), long-term monitoring and evaluation (IDFG, BCMFLNRO, Kootenai Tribe, MFWP), habitat restoration (Kootenai Tribe, IDFG, MFWP), and critical uncertainties research (Kootenai Tribe, USACE, IDFG, MFWP).

The following sections provide additional detail regarding major actions associated with each of the three Kootenai Tribe projects and the IDFG project currently under ISRP review, and a summary of the relationships between the four projects. 

Kootenai River Ecosystem Restoration (Nutrient Addition) (199404900)

The primary goal of this project is to recover a productive, healthy and biologically diverse Kootenai River aquatic ecosystem across multiple trophic layers.  This work is important to help mitigate the effects of Libby Dam impoundment on aquatic processes in downstream river reaches.  Currently the project is implementing several nutrient restoration efforts to help mitigate 30 years of lost productivity due to Libby Dam hydro operations.

The primary objective of the project has been to address factors limiting key fish species within an ecosystem perspective.  Major project components completed include: establishment of a comprehensive and thorough biomonitoring program, investigation of ecosystem-level productivity, testing the feasibility of a large-scale Kootenai River nutrient addition experiment, the rehabilitation of key Kootenai River spawning and rearing tributaries, the provision of funding for the Canadian government for nutrient enrichment and monitoring in Kootenay Lake, providing written summaries of all research activities, and, holding an annual workshop with other agencies to discuss management, research, and monitoring strategies related to Kootenai River basin activities.  

A portion of this project is jointly implemented by the Kootenai Tribe and IDFG (the nutrient addition component for the river is a shared responsibility between the agencies).  The Tribe is responsible for the monitoring of lower trophic levels (water quality, algae and invertebrates) while IDFG is responsible for fish community data collections and analyses associated with nutrient addition in the Kootenai River.  Additionally, the Tribe purchases the nutrient supply on an annual basis and IDFG is responsible for nutrient site day- to-day management activities. IDFG, the British Columbia Ministry of Forests Land Natural Resource Operations, and the Tribe coordinate to hold an annual two day workshop center largely around the nutrient restoration efforts on the Kootenai River and Kootenay Lake, referred to as the IKERT meeting. 

Project actions include the following major components:

  • Addition of nutrients in the Idaho Canyon Reach of the Kootenai River and in the south arm of Kootenay Lake in Canada as a mitigative approach to addressing nutrient losses. 
  • A large-scale biomonitoring program covering approximately 235 km of the Kootenai River and key tributaries (in place since 2002). 
  • Targeted tributary restoration associated with Kokanee spawning habitat. 

Addition of nutrients in the Canyon Reach of the Kootenai River and in the south arm of Kootenay Lake (where Kootenai River discharges into the Lake) in Canada are being used as a mitigative approach to addressing nutrient losses.  Nutrient addition of this type are not possible in the Meander Reaches of the Kootenai River because critical environmental conditions that allow for significant primary productivity (i.e., clear, shallow water, rocky substrates) are not present in this reach.  However, nutrient effects, such as organic matter spiraling from the upriver nutrient addition zone, and fish migrations, such as kokanee spawner returns from Kootenay Lake, will likely augment trophic productivity in the Meander Reach over time.  Nutrient additions in the Canyon reach have helped reestablish the food web in the Canyon and further downstream into the Braided Reach (to a somewhat lesser degree, but still significant) since inception in 2005.  The Tribe anticipates that Canyon Reach nutrient addition will compliment habitat restoration work implemented through project 200200200 in the Braided  and Straight Reaches. 

The large-scale biomonitoring program associated with this project covers approximately 235 km of the Kootenai River and key tributaries (see Figure 4 for monitoring sites).  This biomonitoring program is designed to be sensitive to water borne nutrients, species and community level responses within the water chemistry, algal, macroinvertebrate, and fish communities.  In addition, the project developed a fine-scale biomonitoring program in 2005, specifically to monitor the effectiveness of the nutrient addition experiment in the Kootenai River.  This targeted monitoring project is collecting data on algae species dynamics and key water chemistry parameters in the heart of the nutrient addition zone to provide managers with fine-scale information for adaptive management of the nutrient project on a timely basis.

The biomonitoring program provides critical monitoring data to help measure and evaluate the biological response of habitat restoration actions conducted under projects 200200200 and 200200800 as well as supporting the Tribe’s conservation aquaculture program.  Data gathered through this biomonitoring program will also be critical to implementation of the Kootenai River Habitat Restoration Program adaptive management plan and the Tribe’s subbasin-scale adaptive management plan.   

The Tribe began a multi-year stream habitat/biota survey of lower Kootenai River tributaries (between Bonners Ferry and Porthill, Idaho) in 2000.  Similar to efforts in the Kootenai River, an ecosystem-based perspective has been used in development of monitoring plans and restoration work in tributaries. Streams where historical kokanee salmon spawning has occurred were given top priority in the selection of tributaries segments to be restored.  The critical stream segments this project has and will continue to focus on are the area near the confluence of several key tributaries with the Kootenai River on its historical floodplain.  This tributary restoration work and the kokanee response is an important component of larger-scale efforts to enhance the Kootenai River food web.

This project addresses in river conditions only i.e., work is targeted to the aquatic ecosystem within the confines of the river banks, for the most part (some tributary riparian work has occurred and is planned).  Other Kootenai Tribe projects, specifically projects 200200800 and 200200200 will address riparian, wetland and terrestrial ecosystem habitats.

Restore Natural Recruitment of Kootenai River White Sturgeon (Kootenai River Habitat Restoration Program) (200200200)

The goal of the Kootenai River Habitat Restoration Program is to restore and maintain Kootenai River habitat conditions that support (1) all life stages of endangered Kootenai sturgeon and (2) all life stages of native focal species (i.e., burbot, bull trout, kokanee, westslope cutthroat trout, redband trout) through design and implementation of a suite of habitat restoration projects in the Braided, Straight and Meander reaches of the Kootenai River.  Building on nearly two decades of data collection and modeling related to physical habitat conditions in the Kootenai River, and on monitoring and evaluation data collected through IDFG’s project 198806500, and the Tribe’s Nutrient, Operational Loss Assessment, Reconnect, and Conservation Aquaculture projects, and the expertise of regional and local experts, the Tribe in collaboration with regional partners developed the Kootenai River Habitat Restoration Project Master Plan (Master Plan).  The Master Plan identifies limiting factors associated with river morphology, riparian habitat, aquatic habitat (including limiting factors associated with the six focal fish species), and other constraints, treatments to address those limiting factors, and restoration strategies for each river reach. 

Restoration treatments implemented through this project are designed to address: bank erosion and fine sediment inputs to downstream reaches, lack of cover for juvenile fish, lack of off channel habitat for rearing, insufficient depth for Kootenai sturgeon migration, lack of mainstem hydraulic complexity in the form of variable depth and velocity, insufficient pool frequency, simplified food web, lack of surfaces that support riparian recruitment, loss of floodplain connection, lack of coarse substrate for Kootenai sturgeon egg attachment and larval hiding, lack of bank vegetation, lack of off-channel habitat, lack of fish passage into tributaries, and grazing and floodplain land use.

Project actions are based on ecosystem restoration principles and will help to provide habitat attributes for Kootenai sturgeon that are identified in the Libby Dam Biological Opinion (implementation of the project is included in the Libby Dam settlement agreement), in addition to habitat needs for a range of life stages of burbot, bull trout, kokanee, westslope cutthroat trout, and redband trout.  

Project actions include:

  • Design and implementation of habitat restoration projects in the Braided Reaches, Straight Reach under Phase 2 (i.e., 1a and 1b extension, Bonners Ferry Islands, Straight Reach, Middle Braided 2 Meander, Lower Braided 2 Meander, Cow Creek Slough, Cow Creek, Lower Mill Slough, and Mill Slough).  Projects are designed to restore and enhance mainstem, off channel, wetland and floodplain habitat.
  • Design and implementation of a substrate addition project in the Meander Reach near Shorty’s Island (currently presented as a CAP 1135 project) where Kootenai sturgeon are currently spawning over sand and clay substrates.
  • Targeted feasibility analysis, design and implementation of 2 to 3 habitat restoration projects in the Meander Reaches under Phase 2.  Projects are designed to restore floodplain connectivity and off channel habitat in the Meander Reaches with a focus on aquatic species.  This project compliments work for terrestrial communities, but will not address wildlife mitigation or terrestrial objectives.
  • Development and implementation of monitoring and evaluation plans for each individual Phase 2 and Phase 3 project.
  • Implementation of the Kootenai River Habitat Restoration Program adaptive management plan.

Data and analysis to support development of the project Master Plan, concept designs for Phase 2 and Phase 3, and development of preliminary and final designs for all projects has, and will continue to, incorporate data collection and analysis associated with the Nutrient project and Reconnect project (as well as the Operational Loss Assessment project).  Information collected through IDFG monitoring and evaluation activities for Kootenai sturgeon and burbot was also used to support development of the Master Plan, concept designs for Phase 2 and Phase 3, and development of preliminary and final designs is provide through the data collection and analysis associated with the Nutrient project.  The Tribe is coordinating with IDFG, MFWP and other partners (i.e., BCMFLNRO, USACE, USFWS, BPA) to incorporate the most recent data and analysis in each stage of the project design process.  IDFG participates in the Co-manager and Agency Team (CMART) that has helped develop and review the suite of projects proposed under this project and is coordinating with the Tribe to refine the monitoring and evaluation associated with each project as it is designed. 

Biological monitoring and evaluation to determine the biological response to the habitat restoration projects (i.e., 1135 project, and Phase 1, Phase 2 and Phase 3 projects) will be conducted by IDFG under their project 198806500.  The Tribe is coordinating directly with IDFG to review monitoring and evaluation associated with individual projects as those projects are developed.  The Tribe coordinated with IDFG to conduct pre- and post-project side channel monitoring in support of the Phase 1a and 1b projects implemented under this program in 2011.  The Tribe will supplement the IDFG sturgeon and burbot monitoring with additional side channel monitoring in 2012 and is also coordinating with IDFG on development and design of additional side channel monitoring plans.

Information collected through the Nutrient project’s (199404900) biomonitoring will also be used to help measure the biological response to the suite of habitat restoration projects at various trophic levels and among other fish communities.

IDFG and the program managers for the Tribe’s Nutrient project, Reconnect project and Operational Loss project are also participants in this projects Core Adaptive Management Team which will assist in review and analysis of monitoring and evaluation information and in implementation of the project adaptive management plan.

Reconnect Kootenai River with the Historical Floodplain Project (200200800)

The primary goal of the Reconnect project is to investigate and implement actions that enhance terrestrial and lentic habitats by reconnecting the Kootenai River with its historical floodplain in the Kootenai River.  This project was originally categorized as a wildlife habitat restoration project and the project was closely linked to work conducted under the Albeni Falls Wildlife Mitigation Project (199206100) and the Operational Loss Assessment Project (200201100).  The Oploss Project is developing the framework to assess and monitor reconnection opportunities.  Each reconnect or mitigation project can be folded back into the ecological framework developed by the Oploss Project to assess cumulative impacts of multiple projects over time.  Floodplain reconnection activities under this project are purposely associated with the Tribe’s wildlife mitigation program to ensure long-term protection and designed to address both lentic and terrestrial objectives.  Under this project the Tribe has examined the feasibility of reconnecting floodplain habitats with the mainstem in the Meander Reaches of the Kootenai River.  Since 2002, this included identification and initial assessment of the feasibility of reconnecting six tributary/wetland complexes to the mainstem Kootenai River. 

Project actions include the following major components:

  • Complete design, permitting and implementation of the Ball Creek Stream Restoration project.  
  • Complete other floodplain reconnection activities in association with the Albeni Falls Wildlife Mitigation Project (199206100) and the Operational Loss Assessment Project (200201100). The Reconnect Project will initiate reconnection/restoration activities on a newly acquired property under the Albeni Falls project (Nimz Ranch). 
  • Develop a restoration ranking plan for floodplain/wetland reconnection, restoration and wildlife mitigation opportunities.
  • Explore opportunities to create biologic, social, and economic benefits using flood/groundwater storage and implement pilot project.
  • Assess floodplain ecosystem restoration effectiveness and inform prioritization process by implementing adaptive management process.  This includes implementing invasive species control management techniques in floodplain habitats and developing a study plan to assess interaction of trophic and nutrient dynamics between restored floodplain lentic systems and the Kootenai River.

In addition to supporting feasibility assessment work for Ball Creek and completing initial feasibility analysis for reconnecting six other tributary/wetland complexes in the Meander Reaches, LiDAR data collected as part of this project has helped develop a 2D hydrodynamic model that is used to assess Libby Dam hydraulic impacts, model vegetation succession, and simulate restoration effects to the floodplain under the Oploss Project along with supporting development of the Kootenai River Habitat Restoration Program Master Plan and conceptual design of projects to be implemented under project 200200200.

This project will complement and augment habitat restoration work planned in the Meander Reaches under Phase 3 of project 200200200 by creating conditions that help support an enhanced food web, and contribute to a more complex and diverse terrestrial habitat communities for a variety of wildlife focal species and aquatic species.  An important aspect of the Reconnect Project is that it purposefully focuses on wildlife mitigation in the Kootenai River floodplain to ensure long-term protection and enhancement opportunities.  Moreover, the Reconnect Project targets floodplain biotic communities identified by Oploss Project assessments with an emphasis on the intersection between aquatic and terrestrial connectivity.  The complimentary work conducted under project 200200200 will be addressing sturgeon and other focal species (e.g., burbot, kokanee, etc.) mitigation restoration opportunities in the Meander Reaches and focusing primarily on aquatic/riparian restoration objectives.

Biomonitoring data conducted under the Nutrient project (199404900) are used to help inform project design and will help measure the biological benefits of this project.

Kootenai River Fishery Investigations (Kootenai River Resident Fish Mitigation) (198806500)

While the three Kootenai Tribe projects in this proposal cycle (199404900, 200200200 and 200200800) are largely focused on completion of targeted feasibility assessment and implementation of actions to restore habitat (e.g., nutrient addition, mainstem restoration, side-channel restoration, tributary and floodplain reconnection), the Kootenai River Resident Fish Mitigation project (in coordination with biomonitoring conducted under 199404900) is the monitoring backbone that supports the design, monitoring and adaptive management of the various restoration projects.  The Kootenai River Resident Fish Mitigation project is composed of several studies specifically focused on the recovery of white sturgeon (ESA listed), burbot, and salmonid fisheries.

Project actions include the following major components:

  • Monitor spatial and temporal distribution of Kootenai sturgeon spawning events, early May through mid-July by collecting sturgeon eggs on artificial substrates (egg mats).
  • Monitor and evaluate Kootenai sturgeon vital statistics in response to recovery.
  • Monitor and evaluate juvenile and adult burbot population dynamics.
  • Monitor and evaluate burbot early life survival strategies.
  • Monitor and evaluate salmonid vital statistics in response to recovery strategies.
  • Co-manage and evaluate nutrient restoration program.

This project provides monitoring and evaluation to help better understand Kootenai sturgeon response to flow and temperature management operations implemented by the USACE and BPA (in coordination with other partner agencies) and to help inform regional decision-making processes regarding future operations.

This project provides monitoring and evaluation that is helping develop design criteria for Kootenai sturgeon and burbot for the Kootenai Tribe’s project 200200200 including design of the Phase 1, Phase 2, Phase 3 and 1135 projects.

This project provides monitoring and evaluation of Kootenai sturgeon and burbot that will be used to help evaluate, in coordination with information collected through the Tribe’s biomonitoring sites (199404900), the biological response to actions implemented under project 200200200. 

Information developed through this project is used to inform discussions and recommendations developed in the Kootenai River White Sturgeon Recovery Team, Burbot Conservation Committee, Libby Dam Flow Policy and Technical Teams, and the Tribe’s various technical and expert advisory groups (see subsequent discussion).

IDFG is also a partner to the Tribe on project 199404900 which helps support ecosystem restoration through nutrient addition as well as the extensive biomonitoring project.

4. Technical advisory teams, coordination mechanisms, and other critical outreach

A critical element of many of the projects within the Tribe’s Fish and Wildlife Program is the use of technical advisory teams to provide expert technical advice and critical review at various stages of each project.  Not every expert is an expert on every topic .  To address the need for a rigorous and timely level of review and/or design analysis on various projects and to be sure we get interdisciplinary input, a number of the Tribe’s projects have identified specific teams of technical experts representing a range of disciplines specific to the needs of each project (e.g., river restoration implementation or hydraulic engineering, etc.).  These groups fulfill different roles on each of the projects but in all cases are used to enhance the quality of the projects and provide independent review and input at critical junctures.

It was clear from the ISRPs comments that our presentation of the role and purpose of the different groups relative to different Tribal projects was confusing.  For example, in order to make the best use of these expert resources, and in order to assist in integration and information sharing between projects, groups that provide a technical advisory/oversight role for one project (e.g., IKERT for the Nutrient project) may serve as stakeholder outreach or coordination for another project (e.g., Habitat restoration project). 

Following is a summary of the major advisory teams that have been assembled for the Tribal projects that make use of them. Table 3 summarizes the different technical oversight or advisory groups, stakeholder or educational outreach and other complimentary coordination mechanisms associated with each project.

* Projects that are part of this ISRP review.

Following is a summary of the major advisory groups associated with each of the Tribe’s projects.  Where appropriate, membership details are provided for the unique expert technical groups to help illustrate the specific suite of technical expertise that has been assembled to help guide the projects.

Kootenai River Ecosystem Restoration (BPA Project 1994-049-00)

Technical Review Group: International Kootenay/i River Ecosystem Restoration Team (IKERT)

Purpose:  Annual IKERT meetings have occurred since 2000 and have played an important role in organizing and directing activities for this project.  The IKERT group assists with presenting, analyzing, and discussing monitoring and research data collected by Tribal staff and project contractors to meet project objectives.  During the past decade, the group has been heavily involved in review of the nutrient and productivity technical aspects of the project, both for the Kootenai River and Kootenay Lake.  The group has played an important role in designing the Tribe’s trophic level and water quality Biomonitoring program, and nutrient addition feasibility, testing, and implementation. 

Group composition:  All parties involved in the management and/or research of the Kootenai River ecosystem are regularly invited to attend the IKERT annual meeting.  Currently representatives from Kootenai Tribe of Idaho, Bonneville Power Administration, IDFG, MFWP, British Columbia Ministry of Forests Land Natural Resource Operations, the University of Idaho, Idaho State University, and the University of British Columbia attend IKERT functions during most years.  Table 4 lists the IKERT representatives.

Frequency of meetings and/or other coordination:  The larger group meeting (all members) occurs once per year, typically in the spring.  This allows for review of the previous year’s data and to make adjustments prior to the nutrient addition and biomonitoring seasons.  Smaller sub-group meetings occur throughout the year.  One such group is the IKERT nutrient sub-committee which meets via conference call 1-2 times per month during the nutrient addition season (June-Sept.).  Other smaller meetings include discussions concerning sampling designs, sample size, sampling frequency, data analyses, and report and manuscript development occur on approximately a quarterly basis throughout the year.   

Purpose of meetings and/or other coordination:  The primary purpose of the IKERT meetings is to present and review project results within a technical workgroup setting that allows for the interchange of ideas and improvements.  Additionally, the group discusses ecosystem restoration ideas and techniques, and provides a forum for presenting information about related topics in other river systems and other inter-related Kootenai River projects.

Other desired outcomes include technical analyses and input on technical issues, such as nutrient limitation evaluations, that can be used by tribal management for decision-making and adaptive management.  For example this group was responsible for evaluating biological and water chemistry data and making a recommendation to the Tribe and Idaho Dept. of Fish and Game regarding whether to add or not add nutrients to the Kootenai River in 2004.

At times, the IKERT meeting will be combined with an Adaptive Environmental Assessment (AEA) workshop to plan and coordinate all Kootenai River Projects in the Idaho reaches of the river.  This allows for a "big-picture" view of fish and wildlife projects in the subbasin and how to best coordinate them to recover the Kootenai River ecosystem.  These have typically occurred on a 5-year basis.  As the Kootenai Tribe’s subbasin-scale adaptive management plan moves forward to completion we will review coordination with the AEA workshop.

Kootenai River Floodplain Ecosystem Operational Loss Assessment, Protection, Mitigation and Rehabilitation Project (BPA Project 200201100)

Technical Review Group: Research Design and Review Team (RDRT)

Purpose:  The purpose of the RDRT is to provide input, reviews, and critiques of project methodology, implementation, analyses results, and interpretation.  The RDRT helps to incorporate this information into the Operation Loss Assessment.

Group composition: RDRT includes invited experts from a range of relevant disciplines including terrestrial wildlife ecology, floodplain and vegetation ecology, wetland ecology, invertebrate ecology, hydrology, Libby Dam operations, modeling expertise, etc.  Table 5 presents the RDRT members.

 Frequency of meetings and/or other coordination:  The RDRT and RDRT subgroups are convened as necessary at appropriate times during the development of methods and/or review results of analyses.  Typically, a subgroup is convened at least quarterly, with a full group meeting occurring annually.

Purpose of meetings and/or other coordination:  The purpose of the annual meeting and quarterly subgroup meetings is to inform, discuss, review, critique and recommend project related activities and direction.

Kootenai River Habitat Restoration Project (BPA Project 2002-002-00)

Technical Review Groups: Peer Reviewer Advisory Team (PRAT), Co-manager/Agency Review Team (CMART), Kootenai River Habitat Restoration Program Policy Team (KRHRP PT), Modeling Review Group, and Core Adaptive Management Team (CAMT).

Peer Reviewer Advisory Team (PRAT): The purpose of the Peer Advisory Review Team (PRAT) is to provide additional depth of expertise to the Tribe’s design team.  The PRAT assists in development and review of design concepts, preliminary designs and feasibility analysis, and final design. PRAT members are also available on an on-call basis to provide specific input into development of design criteria, review or interpretation of modeling outputs, or one-on-one assistance with design components. The design team has made regular use of PRAT members in this capacity, seeking advice on subjects such as development of a literature review of salmonid habitat requirements, assistance in development of side channel design criteria, a site visit to the lower Columbia River to view and interpret sturgeon spawning habitat characteristics with a local expert, and review of structural feasibility of design components in the Phase 1a and 1b projects.  Table 6. summarizes the PRAT representation.

Other advisory Kootenai River Habitat Restoration Project technical groups

Co-manager and Agency Review Team (CMART): The Tribe established the CMART to provide a venue for discussion, review of design concepts and preliminary and final design. The intent was to ensure comprehensive information sharing among the co-managers and agency partners who are working in the Kootenai subbasin, and also the Federal agencies who have legal obligations under the ESA and Tribal Trust with the project design team. The primary purpose of this group is to ensure that best available science is incorporated into the development, design and implementation of restoration projects and that projects are developed in a collaborative manner.

Participants include technical representatives from: Idaho Department of Fish and Game (IDFG), Montana Department of Fish Wildlife and Parks (MFWP), B.C. Ministry of Forests Land Natural Resource Operations (BC MFLNRO formerly BC Ministry of Environment), U.S. Fish and Wildlife Service (USFWS), U.S. Army Corps of Engineers (USACE), U.S. Geological Survey (USGS), BPA, Kootenai Tribe (including program managers for other projects), and University of Idaho.  This group also includes the Kootenai River White Sturgeon Recovery Team members, individuals involved in implementation of the Burbot Conservation Strategy, and project managers for the Tribe’s other ecosystem restoration projects (e.g., Operational Loss, Reconnect, and Ecosystem).

Core Adaptive Management Team (CAMT): The CAMT includes many participants from the CMART but the purpose of this group is specifically to review monitoring and evaluation plans for individual projects, and participate in annual adaptive management reviews of the KRHRP. The Tribe will also use the CAMT as a mechanism to ensure coordination with monitoring and evaluation activities conducted by co-managers (e.g., IDFG, BC MFLNRO, MFWP) to better understand the effect of KRHRP projects on focal populations. In the future, as the project progresses, the Tribe may recruit additional expertise to this team to assist in review and interpretation of KRHRP monitoring and evaluation information.

Modeling Review Team: The Tribe has also established a modeling review team, which includes the Tribe’s design team members, and representatives from USGS and USACE (and others as appropriate). The purpose of this group is to review model outputs and interpretations, validate and identify potential adjustments to models, and coordinate efforts to eliminate duplication of effort.

Policy Team: The Tribe also established a Kootenai Habitat Policy Team to help provide policy guidance for the project and to help support effective interaction between policy level agency representatives and field staff. Policy Team members include appointed policy level representatives for the USACE, BPA, USFWS, states of Idaho and Montana, and Confederated Salish and Kootenai Tribes.  NPPC members and staff have also regularly attended Policy Team meetings.

Other major coordination and outreach forums in the Kootenai River subbasin that influence all of three Kootenai Tribe and one IDFG proposal contained in this review.

The following additional coordination and outreach forums play a critical role in the coordination and integration of ecosystem restoration efforts in the Kootenai River.  This information is provided to assist the ISRP in understanding some of the other avenues through which project actions are coordinated.

Kootenai Valley Resource Initiative:  The Kootenai Tribe of Idaho, the City of Bonners Ferry, and Boundary County are working together to address resource issues affecting the Lower Kootenai subbasin. The Kootenai Valley Resource Initiative (KVRI) was formed under a Joint Powers Agreement between the Tribe, the City of Bonners Ferry, and Boundary County in October 2001 to foster community involvement and development in the restoration and enhancement of the resources of the Kootenai Valley.  The initiative includes membership and partners that represent the broad diversity of the community.  The group has been meeting monthly for over ten years.

KVRI is a proactive forum for the community to bring key players to the table, build connectivity between the community and the agencies for information sharing and exchange, as well as to use partnerships and a collaborative approach for community involvement in restoration efforts.  KVRI meets monthly and we use this forum to provide the KVRI board members, agency partners, and community members with information and periodic updates about our projects at key intervals during project implementation.  Additionally, subcommittees can be formed (with the approval of the KVRI board) to address a specific subject or issue in more detail.  Please see information about KVRI subcommittees and how our projects have used them below.  KVRI has also assisted with hosting broad scale public outreach meetings for our projects, as well as the outreach for the development of the Kootenai Subbasin Plan.

KVRI Co-Chairs include Kootenai Tribe of Idaho Tribal Chairperson, Boundary County Commissioner, and Mayor of Bonners Ferry.  KVRI Board Member Representatives include: landowner (Industrial), business/industry, conservationist, soil conservation district/ag landowner, corporate agriculture/landowner, U.S. Forest Service – Idaho Panhandle National Forest, Idaho Fish and Game Commission, and social/cultural/historical.

In addition to the board members, KVRI includes many partners.  KVRI partners include a diverse group of local, state and federal agencies, non-profit organizations, congressional representatives, and community members.  Project outreach occurs at least annually through KVRI and more frequently on an as-needed basis.

KVRI Burbot Subcommittee: Due to changes in the ecosystem over the last century, the burbot in the Lower Kootenai River had collapsed and was proposed for listing.  Through the Burbot Subcommittee of the KVRI, the Tribe facilitated a collaborative process to prepare and implement a conservation strategy to restore the burbot population.   An MOU developed to confirm commitment and guide implementation of the conservation strategy was signed by 16 agencies and entities. By building consensus through the development of the conservation strategy, actions needed to restore burbot and the habitat upon which it depends maintains strong community and agency support. The Tribe coordinates with the KVRI Burbot Subcommittee to gain community input for the support and implementation of this transboundary effort.

The KVRI Burbot Subcommittee includes over 30 members including action agency and co-managers, representatives from non-profit organizations, and community members.  The group meets a least semi-annually to coordinate and review progress.  

KVRI Total Maximum Daily Load (TMDL) Subcommittee: This group was developed in response to an MOA between Kootenai Tribe of Idaho, Idaho Department of Environmental Quality and EPA region10, and the need to coordinate with City and county governments in association with the designation of this committee as a Watershed Advisory Group (WAG) by Idaho DEQ.  The group deals with: Subbasin assessment; load allocation, analysis and implementation; BMP’s for restoration; coordinating partners and responsibility; and looking at new approaches to Temperature TMDL (i.e., potential natural vegetation).

The KVRI TMDL Subcommittee includes 15 members including citizens, county government, Kootenai Tribe, State, Idaho DEQ, farmers, Natural Resources Conservation Service, NGOs, environmental representatives, and the county soil conservation district.  The subcommittee meeting quarterly.

KVRI Wetland/Riparian Subcommittee: This subcommittee developed a reference report for the Tribe, agencies and others to use documenting a decision-making process regarding wetlands and riparian areas in the Kootenai Valley.  The purpose of the group is to balance social, natural resources and economic perspectives; coordinate purchase and restoration of wetlands; work in partnership with IDFG and associated Wildlife Management Areas, and conduct education and outreach.

The KVRI Wetland/Riparian Subcommittee includes 15 to 20 members including citizens, county government, Tribe, IDFG, farmers, USFS, Natural Resources Conservation  Service, NGOs, environmental representatives, county soil conservation district, and forestry, agricultural, industrial representatives.  The group hasn’t met since 2006.  The report resulting from the group’s effort is available at: http://restoringthekootenai.org/resources/F&W-Library/Wildlife/7WL-Final-WRCS.pdf)

KVRI Grizzly Bear Conservation Subcommittee: This subcommittee serves as a forum to disseminate natural resource information, educate community on grizzly bear management and to determine management opportunities.  The purpose of the group is to enhance understanding of grizzly bear life history, population trends/genetics, and habitats needs. 

The KVRI Grizzly Bear Conservation Subcommittee includes 25 members including citizens, county government, Tribe, IDFG, farmers, USFS, Natural Resources Conservation  Service, NGOs, environmental representatives, county soil conservation district, and forestry, agricultural, industrial representatives.  The subcommittee meets quarterly.

KVRI Wildlife Auto-Collision Subcommittee:  This subcommittee serves as a conduit for reaching out to the community for feedback and guidance in considering ways to reduce wildlife conflicts and building support for transportation mitigation efforts.  The purpose of the subcommittee is to implementation of consensus based strategies, identify and increase line-of-sight in area hot spots, collect data to identify hotspots and hotspot changes due to development, and assist with the wildlife crossing database.

The KVRI Wildlife Auto-Collision Subcommittee includes 30 members including citizens, county government, Tribe, IDFG, Idaho Transportation Department, USFWS, USFS, NRCS, US Federal Highways Administration, forestry, agricultural, industrial representatives and NGO environmental representatives.  The subcommittee meets once or twice a year.

KVRI Forestry Subcommittee:  The subcommittee works to enhance understanding and help address federal forest resource issues with the community, including and base planning and coordination using a landscape approach.  The purpose of the is to approach decision making process with a balanced approach and make lands economically, ecologically and socially sustainable, use science-based approaches, develop common ground for natural resource managers and community alike, develop grants for additional restoration opportunities and provide education and outreach.

The KVRI Forestry Subcommittee includes 30 members and includes citizens, county government, Tribe, IDFG, Idaho Transportation Dept., USFWS, USFS, NRCS, loggers, forestry, agricultural, industrial representatives and NGO environmental representatives.  The subcommittee meets quarterly.

Libby Dam Flow Policy and Technical Teams:  Libby Dam flow management coordination, as it relates to BiOp requirements, occurs through the USFWS BiOp/Libby Dam Operations Regional Flow Policy Team coordinated by the USACE.  The Policy Team assigns a Technical Team to summarize the biological and physical considerations for a policy decision regarding sturgeon flow and temperature management at Libby Dam each year. The recommendation is prepared with the specific intent of achieving the requirements of clarified RPA 1 Action 1.5, along with the physical attributes in the Kootenai River thought to positively influence sturgeon spawning success. Success of obtaining certain habitat attributes implemented by the KRHRP will take place in this forum, as well as the USFWS white sturgeon recovery team.  

Group participants include the Federal action agencies and co-managers (BPA, USACE,
USFWS, Kootenai Tribe, IDFG, MFWP).  The group meets annually in the spring to develop and approve flow recommendations for implementation during the sturgeon spawning season.

Kootenai River White Sturgeon Recovery Team:  The Kootenai River White Sturgeon Recovery Team is convened by the U.S. Fish and Wildlife Service.  The Recovery Team shares information and analysis regarding Kootenai sturgeon population status, monitoring and evaluation, research work, habitat restoration initiatives, and provides advice to the U.S. Fish and Wildlife Service.  The group also functions as a forum to review and discuss habitat restoration projects, the Tribe’s Conservation Aquaculture program, etc. 

The KRWSRT is lead by the U.S. Fish and Wildlife Service and includes appointed representatives from BPA, MFWP, IDFG, USACE and BCMFLNRO.  In addition to the formal membership, KRWSRT meetings are attended by a broad range of experts including members of the Upper Columbia River White Sturgeon Recovery Initiative Technical Working Group, sturgeon experts, and representatives of stakeholder groups.  Kootenai River White Sturgeon Recovery Team meetings occur two to three times a year.

5.  Kootenai Tribe’s Kootenai River Draft Subbasin Scale Adaptive Management Plan.  

In a number of the ISRP responses to the Tribe’s projects, the ISRP requested information regarding the draft Kootenai Subbasin Adaptive Management Plan being developed by the Tribe and requested that the draft document be provided.  The Tribe has loaded the working draft document onto the Tribe’s web site at http://www.restoringthekootenai.org/.

We were reluctant to provide this document at this time because this is a working document that is only partially complete and additional coordination and development of the document and associated processes still needs to occur.  This adaptive management plan is not a requirement of the NPCC program nor is it specifically required as a component of any of the Tribe’s projects, this is an initiative that the Tribe has undertaken in order to better manage their overall Fish and Wildlife Program. 

The purpose of the Kootenai Subbasin Adaptive Management Plan is to link each of the projects within the Tribe’s Fish and Wildlife Program via a subbasin scale framework in order to better understand and adaptively manage how those projects collectively contribute to ecosystem restoration in the Kootenai subbasin.  Once completed, the Kootenai Subbasin Adaptive Management Plan is intended to be a living document that will be refined and updated over time as new information becomes available, as results of previous restoration actions are realized, and as the Tribe’s Fish and Wildlife Program continues to mature. 

The Kootenai Subbasin Adaptive Management Plan is intended to provide a framework to formally integrate the Tribe’s various programs and projects.  However, it is important to understand that it is not intended to replace or supersede the specific, detailed monitoring and evaluation or adaptive management components of the individual projects that make up the Tribe’s Fish and Wildlife Program. 

The geographic scope of the adaptive management plan includes the Kootenai subbasin as measured from ridge top to ridge top.  Because this plan is designed to support the Tribe’s Fish and Wildlife Program projects, and because the Tribe has no authority to manage other agencies’ projects or programs, the administrative scope of the plan is limited to the Tribe’s Fish and Wildlife program projects.  However, in recognition of the size and geographic extent of the Kootenai subbasin, and cooperative efforts to manage fish and wildlife resources, data and analysis developed by other agencies will also be used to where possible provide critical supplementary information in support of this adaptive management plan.

The Tribe initially explored development of a program-scale adaptive management plan in 2004.  At that time the Tribe hosted a multi-agency adaptive management workshop designed to collect input from scientific experts and management stakeholders on development of a subbasin scale adaptive management plan.  Topics addressed in this workshop included: 1) identification of particular management options that have potential for restoring key functions in the Kootenai River ecosystem, and important attributes of these options, 2) evaluation of alternative plans for applying combinations of these options over the next few decades, and 3) review of key needs for improvement of monitoring programs in order to insure timely detection of intended immediate effects of each option as well as possible longer-term side effects.  The results of this workshop were recorded in 2005 in the document, Draft Kootenai River Adaptive Management Plan (Walters, Korman, Anders, Holderman, & Ireland, 2005).  For a variety of reasons, primarily related to work load on other projects, this effort was temporarily shelved. This initial document provided a general framework that helped guide the evolution of projects over time, particularly with respect to common ecosystem stressors and responses addressed by multiple projects. 

In 2010, with the completion of the Kootenai River Habitat Restoration Program and the general shift in emphasis of the Tribe’s Fish and Wildlife Program from assessment and evaluation to feasibility assessment and implementation, the Tribe reinitiated efforts to develop a subbasin-scale adaptive management plan in November 2010.  This effort has moved along in a start-and-stop fashion (interrupted by other program work, development of project proposals, etc.) and is currently on hold to be reinitiated in spring 2012. 

In the last review of the document internal Tribal team identified a number of missing items and areas of concern in the current draft document.  Future work sessions will occur in spring through fall of 2012 to: 1) identify and confirm program goals and objectives; 2) refine and finalize the list of metrics used in the program; 3) review and confirm protocols for data storage, confirm methods for data entry, validation, sharing and retrieval; 4) confirm details for coordination with critical non-Tribal entities (e.g., IDFG, BCMFLNRO, MFWP); and 5) develop the agenda and work plan for a fall 2012 meeting to review data from the 2012 field season and develop an initial set of adaptive management recommendations.  The results of this first meeting will be compiled and added to the current draft of the document.  A final review draft of the Kootenai Subbasin Adaptive Management Plan will be distributed prior to the Adaptive Management Team meeting in Fall 2012.  At the fall meeting, we will use the document as a guide for decision-making, and note any additional content that needs to be added so the document is an effective tool for guiding the adaptive management decision-making process.

In addition, the Tribe is in the process of identifying a team of external experts to assist in the review and refinement of the current draft document.  Completion of the final document is scheduled for January 31, 2013.

We hope the ISRP will recognize that this is a partial draft document and still very much a work in progress.  Toward this end, suggestions to improve the overall framework and content would be appreciated and will be incorporated into our future efforts to the extent possible.
