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. |

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).
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).
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.

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. |

(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.
Figure 1. Large-scale, basin-wide monitoring sites on the Kootenai River. The nutrient addition zone, where immediate effects of treatments are expected to be measured, is shaded in orange. Kootenay Lake’s South Arm is shown in the upper left corner of the map.
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
Nutrient Metrics
Periphyton Community Metrics
Primary Production Metrics
Benthic Macroinvertebrates Metrics
Fish Metrics
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:
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:
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:
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:
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 = p1 f1(xi) + p2 f2(xi) + … + pm fm(xi) + eij = ∑km pk fk (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 2. Log soluble reactive phosphorus (SRP) values (milligrams per liter; μg/L) before and after nutrient addition in the Kootenai River nutrient addition zone (KR6, KR9, KR9.1) and the upstream impounded (KR10) and un-impounded (KR14) reference sites.
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.
For more details regarding the study area, methods, data, analyses, results, and discussion regarding nutrients and nutrient responses, please refer to Holderman et al. (2010a) and KTOI (2011).
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).
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).
Figure 5. Log total chlorophyll accrual (mg/m2/30d) before and after nutrient addition in the Kootenai River nutrient addition zone (KR6, KR9, KR9.1), the upstream impounded (KR10) and the un-impounded (KR14) control sites.
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.
For more details regarding the study area, methods, data, analyses, results, and discussion regarding chlorophyll, primary production and their post-treatment responses, please refer to Holderman et al. (2009b) and KTOI (2011).
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).
Figure 13. Log EPT biomass (g/m2) abundance before and after nutrient addition in the Kootenai River nutrient addition zone (KR6, KR9, KR9.1), at the upstream impounded control site (KR10), and the un-impounded (KR14) control site.

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.
For more details concerning the study area, methods, data, analyses, results, and discussion regarding benthic invertebrates, refer to Holderman et al. (2009a) and KTOI (2011).
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.
Figure 27. Abundance (catch/hr) of the six dominant fish species in the Kootenai River before and after nutrient addition at fish biomonitoring sites KR2, KR4, KR6, KR9, KR9.1 (treatment), KR10 (control, regulated), and KR14 (control, un-regulated).

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).
Figure 29. Abundance (catch/hr) of mountain whitefish (Prosopium williamsoni) in the Kootenai River at fish biomonitoring sites KR2, KR4, KR6, KR9, KR9.1(treatment), KR10 (control, regulated), and KR14 (control, un-regulated) from 2003 through 2010.

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:

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.
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.

Figure 34. Comparison of estimated mixture models for two nutrient addition treatments. An example of the positive shift in mean length for age 0 fish is shown (from Shafii et al. 2010).
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).
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.
Figure 37. Fine-scale biomonitoring sites. KRF0 and KRF 1 serve as upstream control sites, KRF2 is the nutrient addition site, and KRF5 through KRF11 are treatment sites.
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
Nutrients Metrics
Periphyton Community Metrics
Primary Production
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:
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:
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:

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).
Figure 39. Mean algal biomass (μg·cm-2·day-1), measured as total chlorophyll accrual rate, at the nutrient monitoring sites in the Kootenai River, Idaho, from June through October, 2006 through 2010.
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.
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.

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. |

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).
The objectives are clearly stated and directly relevant to restoration.
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.
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.
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. Modified by Dal Marsters on 4/13/2012 1:42:17 PM. Modified by Dal Marsters on 4/13/2012 1:42:54 PM. |

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. |

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.

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. |

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. |

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. |

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. |

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. |

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).
The objectives are clearly stated and directly relevant to restoration.
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.
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.
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. Modified by Dal Marsters on 4/13/2012 1:42:17 PM. Modified by Dal Marsters on 4/13/2012 1:42:54 PM. |

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:
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).

Nutrient addition began in 2005; nutrients are added near KR9.1, represented by black vertical line; 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.

KR10 is regulated-reach control; KR14 is control in unregulated reach of the Kootenai River. 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.

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? 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. Please note that the tentative titles and authors provided in table 1 below are confidential and have been supplied to the ISRP by request. For a complete chronological list of all project publications, please refer to the recently submitted project proposal and the Tribe’s website: www.restoringthekootenai.org/ResourcesKootenai/OnlineLibrary/nutrientlibrary/. Table 1. Published manuscripts, technical reports, and anticipated manuscripts for project 199404900 since the last proposal cycle.
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).
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:
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). Table 1. Summary Kootenai Tribe Fish and Wildlife Program projects, year projects were initiated, and BPA project number.
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 1. Primary and secondary limiting factors from Kootenai River Subbasin Plan (KTOI & MFWP 2004). 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. 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:
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:
The ISRP also asked for clarification regarding the relationship of the three Tribal projects to the IDFG Fishery Investigations project in the Kootenai subbasin:
The short summary to the ISRP question is that:
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 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:
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:
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:
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. Table 3. Summary of Kootenai Tribe project technical oversight and/or advisory groups, stakeholder or education outreach and other complimentary coordination 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. Table 4. Core representatives of International Kootenay/i Ecosystem Restoration Team.
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. Table 5. Research Design and Review Team (RDRT) participants.
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. Table 6. KRHRP Peer Reviewer Advisory Team (PRAT) representatives.
Frequency of meetings and/or other coordination: The PRAT meets formally on average twice a year for two-day workshops and is also available on call to provide input and review on an as needed basis. 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, 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. References EPA. 2004.
