Project Title:
Walla Walla Juvenile and Adult Passage Improvements
 
Proposal Short Description:
Provide safe passage for migrating juvenile and adult salmonids in the Walla Walla Subbasin by constructing and maintaining passage facilities at irrigation diversion dams and canals and other passage barriers.
 
Proposal Executive Summary:
Formerly project 1996-011-00, then briefly combined into 2007-396-00. View prior proposal here: http://www.cbfwa.org/solicitation/components/forms/Proposal.cfm?PropID=309

Goal and Why Important:

In the 1990’s, CTUIR, ODFW, and WDFW along with many other agencies began implementing fisheries restoration activities in the Walla Walla Basin. An integral part of this effort is to alleviate the inadequate migration conditions in the basin. Fish populations in the Walla Walla River have been heavily impacted by inadequate passage facilities at diversions and resultant low flows associated with agricultural demands and are a primary factor in the extirpation of spring Chinook salmon and decline of native summer steelhead runs and bull trout in the subbasin.

The Passage Improvements Project goal is to assist in the restoration of salmonid populations in the Walla Walla Basin by increasing adult and juvenile migrant survival. The project provides survival benefits for migrating juveniles and adults by removing passage barriers and constructing or improving fishways and juvenile screens/bypasses. This project will integrate with other fisheries restoration activities in the basin by addressing passage issues imperative to the continued survival and reintroduction of salmonid fish within the basin. It is expected that by providing safe passage for juvenile and adult salmonids, naturally spawning populations will increase.

Improvement of passage conditions has been identified in the Subbasin Summary, Subbasin Plan, Recovery Plans as well as every other Walla Walla Basin planning document, as a critical component in the restoration effort for salmon, steelhead, and bull trout by ensuring that passage conditions are no longer a limiting factor. Section 7.11B of the 1994 Fish and Wildlife Program, identified tributary passage enhancement efforts as necessary to restore fish populations such as those in the Walla Walla Basin.

In the Final Addendum of the Walla Walla Subbasin Plan (Nov 2004), under Section 1.3 “Strategic Project Prioritization Framework” (pages 9-10), adult passage obstructions and inadequately screened water diversions are termed as top priority imminent threats to aquatic focal species in the Walla Walla Basin. The addendum references imminent threat projects that are listed in the May 2004 version of the Subbasin Plan. Among the priority projects that are listed in section 7.3.1 “Imminent Threats and Passage Barriers” in the May 2004 Subbasin Plan are the project sites that are included in this proposal. In addition many of the other passage threats identified may be addressed in part by the cost share portion of the project. These passage issues deal with stream reaches which pass fish to or through priority geographic areas as identified by the Walla Walla Subbasin EDT model. Imminent threats associated with priority geographic areas are described as the highest priority projects in the Walla Walla Subbasin Plan. In addition, fish screens and passage barriers are identified as imminent threats to fish in the Snake River Recovery Plan (2005 Snake River Recovery Plan for Southeast Washington).

The Passage Improvements Project is also directly involved in one of the RPA actions listed in the NMFS 2000 FCRPS Biological Opinion. Although the Walla Walla Basin is not specifically identified in Action 149, the project is involved in activities associated with that Action and listed under Section 9.6.2.1 (Actions Related to Tributary Habitat). Action 150 of the NMFS Biological Opinion states, “In subbasins with listed salmon and steelhead, BPA shall fund protection of currently productive non-Federal habitat, especially if at risk of being degraded…” Habitat above the passage project sites is currently productive. This project will protect and enhance production from those areas.

How Work Will be Accomplished:

The Passage Improvement Project is one of three critically linked projects that comprise the Walla Walla River tributary fish passage effort. This project, along with the Walla Walla Fish Passage Operations (200003300) project and the newly separated operation and maintenance (O&M) project are all required in order to meet passage objectives in the basin. The Passage Improvements Project provides funding for construction of needed passage improvements in the basin. After construction of passage facilities under this project, the Fish Passage Operations Project monitors the facilities to ensure that they are being operated according to designed physical and biological criteria and coordinates daily operation and maintenance with the O&M project.

This project is a coordinated effort between many different private and public interest groups in the basin. Identification and planning of passage improvements for the basin occur through such forums as the Walla Walla Technical Work Group and Mill Creek Working Group. This project provides a source of cost share funding for many projects developed by other private/public entities utilizing primarily non-BPA funding. Daily operation and maintenance of the fish passage facilities is conducted by local irrigation districts under the direction of the Fish Passage Operations Project. Private engineering consultants are contracted for the planning, design, and construction of the identified passage improvements and initial operational evaluation is conducted by PNNL.

All passage improvements are subcontracted out for engineering design and construction. Only engineering firms with previous passage design experience will be selected. Input and review of facility designs and operations are provided by CTUIR, WDFW, ODFW, NMFS, USFWS, Fish Screening Oversite Committee members, and other agency staff with passage backgrounds. All projects will be based on sound scientific principles defined within NMFS design criteria for passage improvements.

Results and Benefits:

Over the last 10 years, this project has taken major strides towards addressing these passage concerns by providing funding for design and/or construction of numerous passage projects have occurred throughout the mid-to-lower Walla Walla Basin. Two decommissioned diversion dams have been removed to provide better upstream passage conditions. Six new ladders have been insalled at lowhead damsto provide better passage conditions. Modern fish screen systems have been built at seven irrigation diversions to protect downstream migrants. Three irrigation ditch consolodation projects have been completed which reduces passage facilities and impacts to fish. In addition, this project has contributed to adult passage improvements in the concrete/weir channel section of lower Mill Creek. Although the majority of passage projects in the Walla Walla Basin have been completed, this proposal identifies additional needs. Passage experts from NMFS, USFWS, WDFW, ODFW, and CTUIR participate in the planning and design of these facilities and incorporate current NMFS passage criteria guidelines.

The project has one objective: To provide safe passage at diversion structures for migrating juvenile and adult salmonids in the Walla Walla Basin. Since the project is primarily construction oriented, the success of the project is more qualitative than quantitative. The major screen sites are evaluated to determine that they meet biological and physical design criteria. These design criteria have been developed and evaluated by NMFS and others and are the most current, up to date guidelines used for passage facility design. The success of the project is primarily evaluated on meeting these design criteria.

Problem Statement: View instructions

The Walla Walla River is heavily diverted for agricultural use. There are two major irrigation diversions located in the mid Walla Walla River at river miles 36 and 47, along with numerous smaller diversions. Historically, inadequate flow and passage conditions during critical portions of both adult and juvenile migration periods was the primary contributor to the extirpation of salmon and decline of summer steelhead and bull trout populations in the Walla Walla Basin.

Unscreened or inadequately screened irrigation canals and inadequate passage at diversion structures played key roles in the decline of the basin fish populations. Inadequate screening resulted in the irretrievable loss of juveniles down irrigation canals or from impingement injury due to improper screen criteria. Non-existent or improper juvenile bypasses and fishways at diversion structures created migration barriers or caused delays and injury.


What are the ultimate ecological objectives of your project?

Examples include:

Monitoring the status and trend of the spawner abundance of a salmonid population; Increasing harvest; Restoring or protecting a certain population; or Maintaining species diversity. A Project Objective should provide a biological and/or physical habitat benchmark by which results can be evaluated. Objectives should be stated in terms of desired outcomes, rather than as statements of methods and work elements (tasks). In addition, define the success criteria by which you will determine if you have met your objectives. Later, you will be asked to link these Objectives to Deliverables and Work Elements.

Explanation of Recent Financial Performance: View instructions
The contracted amounts in the last few years have been significantly lower than the original working budget amounts in the Accord due to a couple large projects being delayed. The Old Lowden-Bergevin Williams ditch consolidation project NEPA process took longer than anticipated and construction occurred later than originally scheduled. The Mill Creek Bennengton ladder project is delayed due to the COE funding approach being completedly changed from 1135 funding to construction tied to existing O&M. Because this project funds a lot of large projects whose timelines can be difficult to pin down, and because the project does not manage the contracts but rather funds other entities to complete the work, project spending is not consistent from year to year. Accord projects have flexibility to transfer unused funds to future years, so we have done that as necessary to complete work when it is ripe.
Discuss your project's historical financial performance, going back to its inception. Include a brief recap of your project's expenditures by fiscal year. If appropriate discuss this in the context of your project's various phases.

Final Round ISRP Comment:

The proponents present a project aimed at removing barriers and providing diversion screens that is generally well organized. The proposal describes the goals, objectives, and means to achieve proposed actions. The proponents (CTUIR) provide an overarching framework for this and other projects in the region tied to First Foods and Functional Touchstones. The ISRP found this to be an understandable and beneficial framework for this and related projects – we encourage its use more broadly.

The proponents have established productive partnerships with multiple groups and have successfully corrected or eliminated numerous fish passage barriers using agreed-upon approaches among cooperators. Fourteen additional projects are scheduled for the next funding period. These projects will take place in the Walla Walla, Umatilla, John Day, Grande Ronde and Tucannon subbasins. All are designed to improve access and survival of migrating juvenile and adult salmonids and resident bull trout. In future annual reports and work plans, the proponents need to provide information to address the following Conditions:

  1. Explanation of objectives. Table 3 summarizes the project’s objectives (listed as actions and measures) along with a general response expected (i.e., “uplift”). The relationship between the actions and measures, however, is not obvious and appear to propose the same thing stated differently. For example, the first (action) objective is to remove 15 barriers while the second (measure) objective is to restore passage to 150 miles. These seem to just state the same thing with differing metrics (barriers v. miles). Further, the timeline lists 6 major projects. Presumedly, the 15 barrier removal projects are broken into these 6 projects, but that was not clear. The ISRP recommends clarifying these related forms of the objectives during the work plan, annual report, and contracting stages.
  2. Details on procedures. Specific details on implementation objectives and methods used to correct fish passage and diversion screening problems are not described. While no formal response is needed, the ISRP recommends attaching a link or an appendix that briefly describes the standard operating procedures, best practices, or formal guidance and methods used for specific kinds of projects (implementation objectives) in the final work plan or next annual report. The proponents indicate that they follow state passage requirements and projects are selected from OR and WA priority lists, but the specific procedures and criteria are not provided.
  3. M&E matrix - support. As habitat projects and monitoring projects are not presented as part of an integrated proposal or plan, the need for a crosswalk to identify the linkages between implementation and monitoring is extremely important for basins or geographic areas. The ISRP is requesting a response from the Walla Walla Sub-Basin Salmonid Monitoring and Evaluation Project (200003900) to summarize the linkages between implementation and monitoring projects in the basin. We ask this project to assist them in creating the summary and provide information to them about what is being monitored for this implementation project and where and when the monitoring occurs. A map or maps of locations of monitoring actions would be helpful in this regard.
  4. Database availability. The proponents appear to have a useful database, but it was not clear what part was or was not publicly available. The ISRP recommends providing a description of the database and its accessibility in the next annual report.
  5. Climate change and prioritization. The proponents provided a list of climate change issues likely to affect the Walla Walla Subbasin and to recovery of imperiled species in this system. The CTUIR fish habitat project (199604601) also included a strong presentation on climate change, which indicates considerable thinking on this topic and how it will affect the subbasin. What was not clear, however, is how their climate change analysis is used to select specific project actions. Specifically, a high priority action under present or past conditions might be quite different from those under likely climate change scenarios. The ISRP encourages the proponents to continue to refine their projections, coordinate with other projects, and adjust project activities accordingly.

 

Q1: Clearly defined objectives and outcomes

The proposal aims to continue a suite of actions directed at providing passage in several subbasins through diversion dam removal or retrofit, screens, ditch consolidation, and culvert removal/improvement. The ISRP notes that the current project has taken a rather circuitous path to its present form (199601100 was combined with 200739600 and then split out again in the current project). The proponents clearly state the major impediments to the projects’ outcomes, such as water availability and habitat connectivity.

Historically, the project(s) has completed a good number of actions such as diversion dam removal or fish ladder retrofits, screen installations, ditch consolidations, and culvert removals/improvements.

Regarding the proposed objectives, Table 3 frames actions in terms of Goals, Quantitative Actions, Quantitative Measures, and Biological Function Uplift (i.e., response). The connection between action and measure appears to restate the same thing with differing metrics (see Condition 1 above). The proponents state that 10 passage impediments will be targeted based on OR and WA priority (candidate) lists and species benefiting (Table 4). A public process is described for determining final selection although specifics are not presented (see Condition 2 above).

Like most of the Walla Walla or CTUIR proposals, the overall, large-scale objectives are the primary focus, and they do a commendable job presenting and discussing these. They have a well-stated project goal which they reframe into a useful biological goal, i.e., "restore longitudinal connectivity, fish passage and habitat quantity.” Objectives of the project are to remove 15 passage barriers. Projects are systematically identified through plans, basin and subbasin plans and so on. There is a process they go through to do this, but for an outsider it is not clear which projects can be selected or the basis for the selection. In short, it is not clear how much of project selection is driven by opportunity, strategic need, or other criteria. Further details on the project selection process should be provided in a subsequent annual report.

Q2: Methods

Implementation methods are generally described, including specific project selection (see above). These are appropriate at a high level. Based on past implementation success, it appears that the proponents have a firm handle on how to undertake such projects and measure their implementation. While no formal response is needed, the ISRP recommends attaching a link or an appendix that covers some of the standard operating procedures, best practices, or formal guidance and methods used for the specific kinds of projects in the final work plan or next annual report (See Condition 2 above).

Federal (NMFS and USWFS) and state (WDFW and ODFW) partners participate with project staff to design culvert replacements, bridges, and structures that incorporate current NMFS and state (Oregon and Washington) fish passage standards. Recently, design criteria have also included elements that facilitate Pacific lamprey passage. Compliance and periodic monitoring are used to determine if the restoration actions are performing as expected. Methods being applied to improve passage appear to be sound based on the proponent’s expertise, collaboration with professionals from outside agencies, and upon the adherence to established fish passage criteria.

Q3: Provisions for M&E

Biological M&E is provided through associated projects. As an implementation project, implementation is provided through contracting and compliance.

At a high level, improving or providing passage (identified as Quantitative Action and Measures Objectives) is expected to lead to benefits to fish and wildlife (identified as Biological Function Uplift). The realization of the “Uplift,” however, implies a sound M&E to observe and measure. As such, the M&E for implementation of barrier removal and improved access will be conducted within the activities of this project; however, the potential biological effects resulting from the project’s actions will be measured by a consolidated M&E project (200003900 and perhaps others). The ISRP recommends coordinating with the M&E project proponents to link specific activities in that project to what can be used to measure a response to passage improvements (see Condition 3. above)

Adaptive management is described at a general level – annual coordination and policy meetings provide the platform for decision making. Some recent trends indicate the outcome of adaptive thinking, although little detail on process or rationale is provided. For example, there appears to be a shift of focus into tributary or smaller systems. In future proposals, it would be useful to understand why proponents are shifting to tributary/smaller system work. Are these priority places, or is there less opportunity to work on mainstem/bigger system projects (or other rationale)?

Q4: Results — benefits to fish and wildlife

The primary obstacles this project addresses are access for fish and wildlife to water and habitat connectivity. The expected benefits (Biological Function Uplift) to anadromous species and resident bull trout are outlined in various ESA, Vision, and Accord documents.

From 2008 to the present the project has successfully removed or corrected 48 passage barriers and updated 14 irrigation screens and improved anadromous fish access to an estimated 725 miles of stream habitat all within the Ceded Lands of the CTUIR. Additionally, all the project deliverables mentioned in the 2013 Geographic Review, with one exception, have been completed or are in the planning and design stages.

Ultimately, documenting benefits to fish and wildlife requires sound M&E to evaluate the effectiveness of the implementation objectives at achieving the predicted biological function uplift. The proponents describe a lengthy list of climate change issues on page 27; however, it is not clear how all the partners in the basin are looking ahead to incorporate climate change into management actions and decisions (see Condition 5 above).

Final Round ISRP Comment:

The sponsors and their local partners worked with three engineering firms to develop fish passage solutions for a six-mile long section of Mill Creek. This portion of the stream flows through the town of Walla Walla. For two miles, it passes through a concrete flume and approximately 800 feet of the flume is roofed over by parking lots and other structures. An additional 3.2 miles of the stream contains 263 concrete sills or channel stabilizers that are six feet wide and stretch across the stream. Some twelve different types of stream reaches were identified in this six-mile section, each with its own fish passage challenges. A physical model of parts of the flume was built and dye studies were performed to estimate how flow patterns and water velocities would react to physical modifications. In addition, a fish energetics model plus field calibrated HEC RAS and spreadsheet models were used to calculate hydraulics. Fish passage ability through the six mile section of Mill Creek at different flow rates and fish sizes by species was estimated via modeling. These results were used to help design modifications to the six-mile section of Mill Creek that would enhance fish passage. Cost estimates for each type of modification were also produced. Additionally, on-the-ground alterations using the suggested designs were made to a portion of the flume and also on a few concrete sills.

The purpose of two of the project’s deliverables is to continue to alter the flume and sills using the same type of modifications that were employed in the pilot work. We suggest that the sponsors install PIT tag detectors and other possible sensors in some of the modified portions of the flume to determine if resting areas and other portions of the modified structures are performing as expected. Corrections or alterations to existing designs that are based on model outputs cannot be made without empirical passage assessments. If the sponsors have pre-treatment fish passage success data under different flow regimes it may also be possible to perform BA or BACI analyses on the cumulative effects of all changes made in the six mile section of Mill Creek.

During the ISRP field visit it was also mentioned that the roofed portion of the Mill Creek flume was in poor condition. We hope that the sponsors and their partners can work with the City of Walla Walla to see if the roof can be removed and that during this process the stream channel in this part of the flume can be redesigned to enhance fish passage.

The Nursery Bridge Dam is another significant fish passage challenge in the Walla Walla subbasin. Currently high velocities at the dam are causing the streambed to undercut areas directly below the dam and are also reducing the effectiveness the dam’s fish ladder. One of the project’s deliverables calls for installing rough material immediately below the dam to reduce water velocities and simultaneously help with entry into the fish ladder. The river channel at the dam is restricted and water flows can also be impacted by irrigation withdrawals. The sponsors and their partners appear to have a holistic plan for this site which calls for widening the river channel below the dam which would reduce water velocities and installing three or more aquifer recharge sites to provide flows during the irrigation season. This appears to be a good approach to solving a significant fish passage problem and we hope that timely progress can be made on completing this plan.

Overall the project is making an important contribution to fish recovery in the Walla Walla Basin. The proposal, however, would have benefitted from additional detail about work elements, deliverables, past project activities, and information about project effectiveness.

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

Inadequate passage at irrigation diversion dams, canals and other passage barriers were identified as top imminent threats to salmonids in the Walla Walla subbasin plan. The objective of this project is to provide safe passage for migrating juvenile and adult salmonids by constructing and maintaining fish passage facilities. The sponsors state that important passage work has been accomplished in the subbasin but that additional problems still exist. Forums such as the Walla Walla Technical Work Group and Mill Creek Working Group identified and helped plan the work being proposed. Projects were prioritized based on their expected impacts on migrating fish. That is mainstem structures that all fish must pass and large irrigation diversion screens were considered high priority projects. In the current proposal, six out of the eight proposed passage projects will help anadromous fish reach portions of upper Mill Creek. The significance of this project to the fish resources of the Walla Walla Basin is clear. The project addresses a mortality factor identified as a key limiting factor in most of the restoration plans that have been developed for this watershed.

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

Results and accomplishments of the project are presented as a list of actions that have been completed. For example, under this project two decommissioned irrigation diversion dams have been removed, six new fish ladders have been installed at low head dams, modern fish screens have been installed at seven irrigation diversions, three irrigation ditch consolidations have been completed which helped reduce the number of passage facilities needed, and alterations to a concrete channel located in lower Mill Creek were made. However, there is insufficient information provided to convey the relative significance of these projects. More detailed information on project accomplishments should be included in the proposal.

Radio telemetry studies on spring Chinook from 2004-2008 were performed to document adult passage in the Walla Walla River. Results from this work were used to make improvements to passage facilities at Hofer, Mill Creek, Gose Street, and the Nursery Bridge Dam. So there is some element of adaptive management incorporated into the project. However, the lack of project-specific effectiveness evaluations limits the availability of information that is required to adaptively improve project effectiveness. For example, even though a project might meet NOAA fish passage standards was there some specific feature at the site that required some modifications? Is there a central site where past experience is stored so that future learning can take place? Some enhancement in project-level effectiveness monitoring would be worth considering.

Evaluation of Results

The Walla Walla River has been heavily diverted for irrigation purposes. Two major irrigation diversions, one at river mile 36 and another at river mile 47 along with numerous smaller diversions exist in the subbasin. These structures played a significant role in the extirpation of spring Chinook and in the reduction of summer steelhead and Bull Trout abundance. Migrating juveniles were lost down irrigation canals and injured by impingement on inappropriate fish screens. Adults were prevented from making upstream migrations either by a complete absence of water or by impassable barriers. Numerous passage improvements have been made. The effectiveness of individual projects, however, has not been evaluated. Visual inspections are made to see if adults or juveniles show any reluctance to moving through specific passage structures but are not done in a quantifiable manner. However, the sponsors have performed studies that show mean travel time of spring Chinook from McNary Dam to the Nursery Bridge Dam has decreased from 30 days in 2000 to 18 days. SAR values for spring Chinook have also gone up a bit since 2004 and the successful re-introduction of spring Chinook into the South Fork of the Walla Walla and into Mill Creek indicate biological benefits have been derived from the passage work that has occurred in the subbasin.

3. Project Relationships, Emerging Limiting Factors, and Tailored Questions

The Walla Walla Juvenile and Adult Passage Improvement project is directly linked to the Walla Walla Fish Operations and Maintenance and the Walla Walla Basinwide Tributary Passage and Flow projects. The juvenile and adult passage project provides support for the installation of screens and passage structures at irrigation diversion sites, dams, and other sites where fish passage has been impaired. The operation and maintenance project handles the O&M for these installations while the basinwide tributary passage project focuses on flow augmentation. These projects have made significant progress towards addressing fish impacts related to the irrigation system in the Walla Walla Basin.

Project identification is done by the Walla Walla Technical Work Group, the Mill Creek Working Group, and other interested entities. Private engineering firms design and construct passage improvements, and these plans are reviewed by the sponsors (CTUIR) along with WDFW, ODFW, NMFS, and the USFWS. PNNL personnel are engaged by the project to inspect newly completed projects to determine if they are operating under accepted NMFS criteria. The project also provides cost share funds for fish passage projects led by the Army Corps of Engineers, Snake River Salmon Recovery Board, NOAA, Milton-Freewater Water Control District, and the Walla Walla Basin Watershed Council.

Additionally, the project is linked to the Walla Walla Basin Monitoring and Evaluation Project (BPA Project Number 2000-039-00) which performs basinwide assessments of fish response to habitat improvement efforts. This Monitoring and Evaluation project appears to be collecting comprehensive data on steelhead and spring Chinook populations in the river and some of the results from this study are presented. VSP parameters appear to be trending upwards. However, it is not possible to determine the role improved passage survival is playing in this trend. Assessments of effectiveness of the screens and passage structures installed under this program appear to be limited to behavior displayed by radio-tagged adult fish near passage structures and casual observations of fish behavior around project sites. A more rigorous assessment of the efficacy of the structures should be considered.

No emerging limiting factors were presented. It is clear however, that climate change and possible shifts in irrigation water use will impact fish passage. How to accommodate these changes in flow regimes and water temperature will need to be considered in future fish passage planning, design, and construction.

4. Deliverables, Work Elements, Metrics, and Methods

Ten project deliverables are presented. Eight of them are for specific fish passage projects. Many of these have been designed and are ready for construction. One of the remaining deliverables is for cost-sharing. In this case funds from the project will be provided to other subbasin groups that are performing fish passage work. Previous examples of cost sharing include projects on the Touchet, Garrison Creek, Spring Creek, and at Gose Street. The final deliverable pays PNNL personnel to perform post-project evaluations to ensure that newly completed projects meet NOAA fish passage criteria. The work elements and deliverables for this project seem appropriate. They are primarily related to the construction of new screens or fish ladders or modification of existing facilities. However, the detail about each work element and deliverable was quite brief. Additional detail or links to information about each planned project would have been useful in reviewing the proposal.

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

Inadequate passage at irrigation diversion dams, canals and other passage barriers were identified as top imminent threats to salmonids in the Walla Walla subbasin plan. The objective of this project is to provide safe passage for migrating juvenile and adult salmonids by constructing and maintaining fish passage facilities. The sponsors state that important passage work has been accomplished in the subbasin but that additional problems still exist.

Radio telemetry studies on spring Chinook from 2004-2008 were performed to document adult passage in the Walla Walla River. Results from this work were used to make improvements to passage facilities at Hofer, Mill Creek, Gose Street, and the Nursery Bridge Dam. So there is some element of adaptive management incorporated into the project.

For example, even though a project might meet NOAA fish passage standards was there some specific feature at the site that required some modifications?

Evaluation of Results

The Walla Walla River has been heavily diverted for irrigation purposes. Two major irrigation diversions, one at river mile 36 and another at river mile 47 along with numerous smaller diversions exist in the subbasin. These structures played a significant role in the extirpation of spring Chinook and in the reduction of summer steelhead and Bull Trout abundance. Migrating juveniles were lost down irrigation canals and injured by impingement on inappropriate fish screens. Adults were prevented from making upstream migrations either by a complete absence of water or by impassable barriers. Numerous passage improvements have been made. The effectiveness of individual projects, however, has not been evaluated. Visual inspections are made to see if adults or juveniles show any reluctance to moving through specific passage structures but are not done in a quantifiable manner. However, the sponsors have performed studies that show mean travel time of spring Chinook from McNary Dam to the Nursery Bridge Dam has decreased from 30 days in 2000 to 18 days. SAR values for spring Chinook have also gone up a bit since 2004 and the successful re-introduction of spring Chinook into the South Fork of the Walla Walla and into Mill Creek indicate biological benefits have been derived from the passage work that has occurred in the subbasin.

3. Project Relationships, Emerging Limiting Factors, and Tailored Questions

The Walla Walla Juvenile and Adult Passage Improvement project is directly linked to the Walla Walla Fish Operations and Maintenance and the Walla Walla Basinwide Tributary Passage and Flow projects. The juvenile and adult passage project provides support for the installation of screens and passage structures at irrigation diversion sites, dams, and other sites where fish passage has been impaired. The operation and maintenance project handles the O&M for these installations while the basinwide tributary passage project focuses on flow augmentation. These projects have made significant progress towards addressing fish impacts related to the irrigation system in the Walla Walla Basin.

Project identification is done by the Walla Walla Technical Work Group, the Mill Creek Working Group, and other interested entities. Private engineering firms design and construct passage improvements, and these plans are reviewed by the sponsors (CTUIR) along with WDFW, ODFW, NMFS, and the USFWS. PNNL personnel are engaged by the project to inspect newly completed projects to determine if they are operating under accepted NMFS criteria. The project also provides cost share funds for fish passage projects led by the Army Corps of Engineers, Snake River Salmon Recovery Board, NOAA, Milton-Freewater Water Control District, and the Walla Walla Basin Watershed Council.

Additionally, the project is linked to the Walla Walla Basin Monitoring and Evaluation Project (BPA Project Number 2000-039-00) which performs basinwide assessments of fish response to habitat improvement efforts. This Monitoring and Evaluation project appears to be collecting comprehensive data on steelhead and spring Chinook populations in the river and some of the results from this study are presented. VSP parameters appear to be trending upwards. However, it is not possible to determine the role improved passage survival is playing in this trend. Assessments of effectiveness of the screens and passage structures installed under this program appear to be limited to behavior displayed by radio-tagged adult fish near passage structures and casual observations of fish behavior around project sites. A more rigorous assessment of the efficacy of the structures should be considered.

No emerging limiting factors were presented. It is clear however, that climate change and possible shifts in irrigation water use will impact fish passage. How to accommodate these changes in flow regimes and water temperature will need to be considered in future fish passage planning, design, and construction.

4. Deliverables, Work Elements, Metrics, and Methods

Ten project deliverables are presented. Eight of them are for specific fish passage projects. Many of these have been designed and are ready for construction. One of the remaining deliverables is for cost-sharing. In this case funds from the project will be provided to other subbasin groups that are performing fish passage work. Previous examples of cost sharing include projects on the Touchet, Garrison Creek, Spring Creek, and at Gose Street. The final deliverable pays PNNL personnel to perform post-project evaluations to ensure that newly completed projects meet NOAA fish passage criteria. The work elements and deliverables for this project seem appropriate. They are primarily related to the construction of new screens or fish ladders or modification of existing facilities. However, the detail about each work element and deliverable was quite brief. Additional detail or links to information about each planned project would have been useful in reviewing the proposal.

Review: FY07-09 Solicitation Review
Completed Date: 8/31/2006
Final Round ISRP Date: None
Final Round ISRP Rating: Meets Scientific Review Criteria (Qualified)
Final Round ISRP Comment:
This is one of three closely linked passage proposals in the Walla Walla subbasin. Most of the proposal is well done. The proposal would be improved by reporting results from the subbasin level M&E project in summary format. The project needs to make the connection to biological data collected in the M&E project. This was a similar concern with previous ISRP reviews, and while there has been some improvement, it should be clear by now that projects must indicate results of past efforts clearly, particularly after 10 years of efforts. The efforts and results must be linked to subbasin plans, and this was not a strong area of the proposal. What data will be collected by other entities to evaluate success (or failure)? What are the key reference points from this data that will affect management decisions?

A main ISRP comment for the 2007-2009 last project review was: &quot;The proposal would be improved by reporting results from the subbasin level M&amp;E project in summary format. What data will be collected by other entities to evaluate success (or failure)?&quot;<br/> <br/> All passage projects were initially identified as limiting factors in various subbasin planning efforts. This identification was based on lack of fish passage facilities (no ladder or screen) or facilities that were known to not comply with current NOAA fish passage criteria. Information from field biologists (observations of smolts congregating and having difficulty bypassing back to river or observation of adults unseccessfully jumping at diversion dams, etc.) also contributed to the limiting factor assessment. Following construction of passage projects, PNNL performs operational checks to make sure facilities comply with NOAA fish passage criteria. This does not confirm biological benefits but is the first step to confirm physical conditions necessary for biological benefits. Ocular field observations at new fish passage facilities from biologists and operations personnel have not documented fish passage problems that were observed prior to construction.<br/> <br/> The CTUIR has implemented a comprehensive Walla Walla water and fish restoration strategy that includes: fish passage improvements (i.e. Walla Walla O &amp; M), instream flow enhancement, artificial propagation-salmon reintroduction, watershed protection and restoration, stream habitat enhancement, harvest management, and monitoring and evaluation. The Walla Walla Salmonid Monitoring and Evaluation Project (BPA Project Number 2000-039-00) has provided cumulative time series data (primarily 2000 – 2012) to describe the current state of the available information or to evaluate trends, where possible (Mahoney, et al. 2013, <a href="http://data.umatilla.nsn.us/" target="_blank">http://data.umatilla.nsn.us/</a>). This research, monitoring and evaluation effort is the continuation of a coordinated and collaborative approach to improve monitoring of summer steelhead and bull trout stock status, as well as to evaluate spring Chinook reintroduction efforts and natural population rebuilding within the Walla Walla Subbasin. Our focus is to describe adult abundance and stock productivity, (e.g. adult escapement, adult to adult replacement, smolt to adult return, and migration travel time) for steelhead and spring Chinook. Numerous programmatic salmonid protection and restoration actions have been implemented in the subbasin and while it is difficult to measure the effectiveness of any particular project (i.e. habitat, hatchery, or O &amp; M), our results suggest the program to be performing well.<br/> The Umatilla tribe’s spring Chinook reintroduction in the Walla Walla River is demonstrating how adult fish will return, spawn, and rear in available habitat. Since the program began, adult spring Chinook returns to the upper Walla Walla River and Mill Creek have increased from 200 fish in 2004 (the first year of age 4 returns) to 1,135 in 2009. Due to the program’s success, the tribe was able to open a tribal fishery on the Walla Walla in 2010, for the first time in nearly a century. Since 2004, naturalized spring Chinook escapement past Nursery Bridge Dam (NBD, river mile 45) has shown a significant upward trend from zero to up near 300 (R2 = 0.8226). The 9-year (2004-2012) geometric mean for naturalized adult spring Chinook to NBD was 153.1 (SE 31.0) fish. Since 2005, eight complete brood years (BY2000-07; i.e. age 3, 4 &amp; 5 fish) have returned to NBD. Adult replacement was met for BY 2005 (1.27) and nearly met for BY 2006 (0.71). Since 2000, we have observed a moderate upward trend (R2 = 0.2062) towards replacement driven largely by the 2005 brood. Understanding fish passage at BPA funded facilities is a necessary and mandated component for determining success of fish passage restoration actions. Between 2004 and 2008, we used radio telemetry to describe adult migration and fish ladder use by adult spring Chinook. Results documenting ladder use were used to support subsequent improvements in fish passage at Hofer, Mill Creek, Gose Street, and NBD fish ladders. Mean travel time through the Walla Walla River has been reduced by the removal of passage barriers and efficient fish ladder passage. Since 2000, we have observed a downward trend (from 30 to about 18 days; R2 = 0.7250) in mean travel time between McNary Dam and NBD; resulting in improved adult spawning escapement. Finally, smolt to adult return (SAR) to NBD was estimated to describe trends in naturalized production. Since 2000, we have observed a moderate upward trend (R2 = 0.37) in naturalized SAR driven largely by the 2005-2007 broods. While our monitoring efforts highlighted above do not specifically measure the effectiveness of any particular project, the improving trends do suggest that the program as a whole is performing well and that improved passage conditions likey contributed to this success


Project Level: Please discuss how you’ve changed your project (objectives, actions, etc) based on biological responses or information gained from project actions; because of management decisions at the subbasin state, regional, or agency level; or by external or larger environment factors. Specifically, regarding project modifications summarize how previous hypotheses and methods are changed or improved in this updated proposal. This would include project modifications based on information from recent research and literature. How is your new work different than previous work, and why?
Management Level: Please describe any management changes planned or made because of biological responses or information gained from project actions. This would include management decisions at the subbasin, state, or regional level influenced by project results.
Management Changes: View instructions
As fish passage projects have been implemented, the overall objectives or actions have remained the same - provide safe passage at diversion structures for migrating juvenile and adult salmonids in the Walla Walla Basin. Actions have varied as site specific factors require but in all cases, juvenile and adult fish passage has been improved and confirmed to be compliant with NOAA fish passage criteria. As this project has improved fish passage conditions in the Walla Walla Basin, fish managers have implemented new actions such as spring Chinook reintroduction. Adult outplanting and release of juviniles did not occur until most of the major fish passage improvements had been completed. More improvements are necessary but the main one have been addressed by this project.

The table content is updated frequently and thus contains more recent information than what was in the original proposal reviewed by ISRP and Council.

The Project Relationships tracked automatically in CBFish provide a history of how work and budgets move between projects. The terms "Merged" and "Split" describe the transfer of some or all of the Work and budgets from one or more source projects to one or more target projects. For example, some of one project's budget may be split from it and merged into a different project. Project relationships change for a variety of reasons including the creation of efficiency gains.
Project Relationships: This project Merged From 1996-011-00 effective on 9/11/2009
Relationship Description: Project 1996-011-00 was combined with 2007-396-00, however with the signing of the Fish Accords, the Umatilla Tribe portion was split out again. Initially, 1996-011-00 was used and contracts were set up, since that project hasn't been funded since 2006, BPA management decided to start a new project


Additional Relationships Explanation:

1996-011-00 - Project work for this project was originally completed under 1996-011-00 prior to being combined into 2007-396-00.

2007-396-00 - 1996-011-00 was, for a short time, combined with two other project proposals (2007-330-00 and 2002-039-00) into 2007-396-00.  After the Accords were signed, CTUIR's portion of the project was separated out again into the current project number 2009-026-00.  Some work done by CTUIR still remains attached to that project and is described in the history section.

2007-217-00 - O&M of the major facilities after completion is conducted by local irrigation districts and is now covered under 2007-217-00.  This work was originally part of this project as 1996-011-00 but has since been separated.

2000-033-00 - the CTUIR Fish Passage Operations project monitors and coordinates operation of the facilities after construction to ensure that they are operated within passage guidelines and to assess any operational problems or issues.

2000-039-00 - Walla Walla Basin Monitoring & Evaluation.  This M&E project assesses fish populations in the basin.

2000-038-00 and -01 - Walla Walla Hatchery Planning & Construction.  2009-026-00 and its predecessor 1996-011-00 have provided the foundation of passage and adequate flow in the Walla Walla basin that will allow the hatchery efforts to be successful.

This project is a coordinated effort between many different private and public interest groups in the basin. Identification and planning of passage improvements for the basin occur through such forums as the Walla Walla Technical Work Group and Mill Creek Working Group. This project provides a source of cost share funding for many projects developed by other private/public entities utilizing primarily non-BPA funding.


Primary Focal Species
Chinook (O. tshawytscha) - Mid-Columbia River Spring ESU

Types of Work:

Small project cost-sharing funds (DELV-9)
This project has always been available to provide smaller amounts of cost-share on other projets for basin stakeholders. Some other funders, such as the Snake River Salmon Recovery Board, require a certain amount of cost-share as a condition of their funding. The project plans to continue offering approximatly $250,000 per year to help achieve subbasin passage goals. Cost share funding was requested and provided by this project for the Touchet, Garrison Creek, Gose Street, Spring Creek, and other past projects.
Types of Work:

Post-construction passage facility criteria check (DELV-10)
This is Expense rather than Capital. Immediately following completion of project construction, Pacific Northwest National Laboratory (PNNL) has been used and will continue to be used to confirm that new facilities and operations meet NOAA fish passage criteria.
Types of Work:

Major Facilities and Equipment explanation:
Many passage improvements have been made which have improved fish passage conditions in the Walla Walla Basin. The construction of passage facilities at additional sites is requested within this proposal. In addition, cost share funding is expected to be available to address passage projects. As these projects are completed, passage conditions on both the individual and basin-wide scale will improve. All projects will be based on sound scientific principles defined within NOAA disign criteria for passage improvements. Engineering firms utilized in the design of these facilities will be required to have passage facility experience. Subcontractors hired for design, construction and evaluation will be expected to have the experience and/or resources necessary to perform the required tasks.

Final Round ISRP Comment:

The sponsors and their local partners worked with three engineering firms to develop fish passage solutions for a six-mile long section of Mill Creek. This portion of the stream flows through the town of Walla Walla. For two miles, it passes through a concrete flume and approximately 800 feet of the flume is roofed over by parking lots and other structures. An additional 3.2 miles of the stream contains 263 concrete sills or channel stabilizers that are six feet wide and stretch across the stream. Some twelve different types of stream reaches were identified in this six-mile section, each with its own fish passage challenges. A physical model of parts of the flume was built and dye studies were performed to estimate how flow patterns and water velocities would react to physical modifications. In addition, a fish energetics model plus field calibrated HEC RAS and spreadsheet models were used to calculate hydraulics. Fish passage ability through the six mile section of Mill Creek at different flow rates and fish sizes by species was estimated via modeling. These results were used to help design modifications to the six-mile section of Mill Creek that would enhance fish passage. Cost estimates for each type of modification were also produced. Additionally, on-the-ground alterations using the suggested designs were made to a portion of the flume and also on a few concrete sills.

The purpose of two of the project’s deliverables is to continue to alter the flume and sills using the same type of modifications that were employed in the pilot work. We suggest that the sponsors install PIT tag detectors and other possible sensors in some of the modified portions of the flume to determine if resting areas and other portions of the modified structures are performing as expected. Corrections or alterations to existing designs that are based on model outputs cannot be made without empirical passage assessments. If the sponsors have pre-treatment fish passage success data under different flow regimes it may also be possible to perform BA or BACI analyses on the cumulative effects of all changes made in the six mile section of Mill Creek.

During the ISRP field visit it was also mentioned that the roofed portion of the Mill Creek flume was in poor condition. We hope that the sponsors and their partners can work with the City of Walla Walla to see if the roof can be removed and that during this process the stream channel in this part of the flume can be redesigned to enhance fish passage.

The Nursery Bridge Dam is another significant fish passage challenge in the Walla Walla subbasin. Currently high velocities at the dam are causing the streambed to undercut areas directly below the dam and are also reducing the effectiveness the dam’s fish ladder. One of the project’s deliverables calls for installing rough material immediately below the dam to reduce water velocities and simultaneously help with entry into the fish ladder. The river channel at the dam is restricted and water flows can also be impacted by irrigation withdrawals. The sponsors and their partners appear to have a holistic plan for this site which calls for widening the river channel below the dam which would reduce water velocities and installing three or more aquifer recharge sites to provide flows during the irrigation season. This appears to be a good approach to solving a significant fish passage problem and we hope that timely progress can be made on completing this plan.

Overall the project is making an important contribution to fish recovery in the Walla Walla Basin. The proposal, however, would have benefitted from additional detail about work elements, deliverables, past project activities, and information about project effectiveness.

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

Inadequate passage at irrigation diversion dams, canals and other passage barriers were identified as top imminent threats to salmonids in the Walla Walla subbasin plan. The objective of this project is to provide safe passage for migrating juvenile and adult salmonids by constructing and maintaining fish passage facilities. The sponsors state that important passage work has been accomplished in the subbasin but that additional problems still exist. Forums such as the Walla Walla Technical Work Group and Mill Creek Working Group identified and helped plan the work being proposed. Projects were prioritized based on their expected impacts on migrating fish. That is mainstem structures that all fish must pass and large irrigation diversion screens were considered high priority projects. In the current proposal, six out of the eight proposed passage projects will help anadromous fish reach portions of upper Mill Creek. The significance of this project to the fish resources of the Walla Walla Basin is clear. The project addresses a mortality factor identified as a key limiting factor in most of the restoration plans that have been developed for this watershed.

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

Results and accomplishments of the project are presented as a list of actions that have been completed. For example, under this project two decommissioned irrigation diversion dams have been removed, six new fish ladders have been installed at low head dams, modern fish screens have been installed at seven irrigation diversions, three irrigation ditch consolidations have been completed which helped reduce the number of passage facilities needed, and alterations to a concrete channel located in lower Mill Creek were made. However, there is insufficient information provided to convey the relative significance of these projects. More detailed information on project accomplishments should be included in the proposal.

Radio telemetry studies on spring Chinook from 2004-2008 were performed to document adult passage in the Walla Walla River. Results from this work were used to make improvements to passage facilities at Hofer, Mill Creek, Gose Street, and the Nursery Bridge Dam. So there is some element of adaptive management incorporated into the project. However, the lack of project-specific effectiveness evaluations limits the availability of information that is required to adaptively improve project effectiveness. For example, even though a project might meet NOAA fish passage standards was there some specific feature at the site that required some modifications? Is there a central site where past experience is stored so that future learning can take place? Some enhancement in project-level effectiveness monitoring would be worth considering.

Evaluation of Results

The Walla Walla River has been heavily diverted for irrigation purposes. Two major irrigation diversions, one at river mile 36 and another at river mile 47 along with numerous smaller diversions exist in the subbasin. These structures played a significant role in the extirpation of spring Chinook and in the reduction of summer steelhead and Bull Trout abundance. Migrating juveniles were lost down irrigation canals and injured by impingement on inappropriate fish screens. Adults were prevented from making upstream migrations either by a complete absence of water or by impassable barriers. Numerous passage improvements have been made. The effectiveness of individual projects, however, has not been evaluated. Visual inspections are made to see if adults or juveniles show any reluctance to moving through specific passage structures but are not done in a quantifiable manner. However, the sponsors have performed studies that show mean travel time of spring Chinook from McNary Dam to the Nursery Bridge Dam has decreased from 30 days in 2000 to 18 days. SAR values for spring Chinook have also gone up a bit since 2004 and the successful re-introduction of spring Chinook into the South Fork of the Walla Walla and into Mill Creek indicate biological benefits have been derived from the passage work that has occurred in the subbasin.

3. Project Relationships, Emerging Limiting Factors, and Tailored Questions

The Walla Walla Juvenile and Adult Passage Improvement project is directly linked to the Walla Walla Fish Operations and Maintenance and the Walla Walla Basinwide Tributary Passage and Flow projects. The juvenile and adult passage project provides support for the installation of screens and passage structures at irrigation diversion sites, dams, and other sites where fish passage has been impaired. The operation and maintenance project handles the O&M for these installations while the basinwide tributary passage project focuses on flow augmentation. These projects have made significant progress towards addressing fish impacts related to the irrigation system in the Walla Walla Basin.

Project identification is done by the Walla Walla Technical Work Group, the Mill Creek Working Group, and other interested entities. Private engineering firms design and construct passage improvements, and these plans are reviewed by the sponsors (CTUIR) along with WDFW, ODFW, NMFS, and the USFWS. PNNL personnel are engaged by the project to inspect newly completed projects to determine if they are operating under accepted NMFS criteria. The project also provides cost share funds for fish passage projects led by the Army Corps of Engineers, Snake River Salmon Recovery Board, NOAA, Milton-Freewater Water Control District, and the Walla Walla Basin Watershed Council.

Additionally, the project is linked to the Walla Walla Basin Monitoring and Evaluation Project (BPA Project Number 2000-039-00) which performs basinwide assessments of fish response to habitat improvement efforts. This Monitoring and Evaluation project appears to be collecting comprehensive data on steelhead and spring Chinook populations in the river and some of the results from this study are presented. VSP parameters appear to be trending upwards. However, it is not possible to determine the role improved passage survival is playing in this trend. Assessments of effectiveness of the screens and passage structures installed under this program appear to be limited to behavior displayed by radio-tagged adult fish near passage structures and casual observations of fish behavior around project sites. A more rigorous assessment of the efficacy of the structures should be considered.

No emerging limiting factors were presented. It is clear however, that climate change and possible shifts in irrigation water use will impact fish passage. How to accommodate these changes in flow regimes and water temperature will need to be considered in future fish passage planning, design, and construction.

4. Deliverables, Work Elements, Metrics, and Methods

Ten project deliverables are presented. Eight of them are for specific fish passage projects. Many of these have been designed and are ready for construction. One of the remaining deliverables is for cost-sharing. In this case funds from the project will be provided to other subbasin groups that are performing fish passage work. Previous examples of cost sharing include projects on the Touchet, Garrison Creek, Spring Creek, and at Gose Street. The final deliverable pays PNNL personnel to perform post-project evaluations to ensure that newly completed projects meet NOAA fish passage criteria. The work elements and deliverables for this project seem appropriate. They are primarily related to the construction of new screens or fish ladders or modification of existing facilities. However, the detail about each work element and deliverable was quite brief. Additional detail or links to information about each planned project would have been useful in reviewing the proposal.
