Section 2. Narrative

Related projects
During the last 50 years, state and federal entities initiated water diversion screening programs and passage improvements throughout the Columbia River Basin. Installation of new screens and improvement of old screens was initiated in the Yakima Basin during 1985. Project 8506200 relates to screen improvement projects throughout the basin. These include: 7.10A.3 (Fisheries Managers maintenance of a prioritized list of tributary screening and passage facilities), 7.10A.4 (National marine Fisheries Service, Working Oversight Committee, Appropriate Technical Work Groups and Bonneville identification of resources needed to accomplish screening and passage and monitoring and evaluation plans), 7.10A.5 (Bureau of Land Management, Idaho and Oregon/Washington Offices; U.S. Forest Service Regions 1,4,6; and Bureau of Reclamation, Pacific Northwest Region requirements that existing and new water use authorizations have functional fish screens and other passage facilities), 7.10A.6 (Corps of Engineers inspection of underwater diversions), 7.10A.7 (Idaho, Oregon, Washington requirements that installation, operation, and maintenance of fish screens are in compliance with state laws), 7.10D (Bonneville's evaluation of Dryden Dam screens), and 7.11 (Improvement of irrigation diversions in the Yakima River basin).

Project history
Project 8506200 began in 1985 with a fisheries evaluation the Sunnyside Canal Fish Screening Facility. Since 1985, project staff have completed fisheries evaluations at: Richland Canal Fish Screening Facility, Toppenish/Satus Canal Fish Screening Facility, Wapato Canal Fish Screening Facility, Toppenish Creek Canal Fish Screening Facility, Westside Ditch Fish Screening Facility, and Town Canal Fish Screening Facility. Water velocity evaluations were also completed at the Columbia Canal Fish Screening Facility, Roza Canal Fish Screening Facility, Easton Canal Fish Screening Facility, and Chandler Canal Fish Screening Facility. Project staff evaluated the potential for migration delay and increased loss to predation at Wapato and Sunnyside Canal Fish Screening Facilities during 1991 operations. They evaluated the Dryden Fish Screening Facility during 1994. In addition, components of modular fish screens were evaluated in the laboratory at Richland during 1994 and 1995.

Biological results achieved
Project staff have conducted fisheries and hydrological evaluations at about 30 fish screening facilities in Washington and Idaho. Additionally, they have conducted laboratory experiments with low volume modular screening facilities. Using the combined results of the evaluations, the project staff have concluded that:
1. Fish are safely returned from irrigation canals back to the river or stream from which they were diverted when fish screening facilities are properly designed, constructed, and maintained.
2. Fish 40 mm in length or larger can be prevented from passing through fish screening facilities when current screening design, construction, and maintenance criteria are followed.
3. Predation rates at fish screening facilities are probably the same as predation rates in the river or stream from which they were diverted, assuming the screen design, construction and maintenance meet current criteria.
4. Migration rates or movement behavior for fish at fish screening facilities are probably the same as those for fish in the river or stream from which they were diverted, assuming the screen design, construction and maintenance meet current criteria
5. Fish screening effectiveness is highly dependent on proper operation and timely maintenance of all components of the fish screen facility.
Fish that are diverted from a river or stream into an irrigation diversion are potentially subjected to conditions that can directly or indirectly impact migration. Fish screening facilities have been installed in irrigation ditches to prevent fish from being diverted into irrigation ditches and to safely return fish to the stream or river from which they have been diverted. Criteria to protect fish screening facilities have been evolving since fish screens were first designed and constructed in the Pacific Northwest. During the 1980s, it became apparent that many diversions were unscreened and many existing screens did not meet the criteria needed to adequately protect fish.
Project staff, beginning with the evaluation of the Sunnyside Canal Fish Screening Facility, examined newly constructed screens to ensure that fish were being protected. Five criteria were established to determine if screens were adequately protecting fish. They are:
1. Fish are not killed or injured as they are diverted from the irrigation canal back to the river.
2. Fish can not pass downstream of the facility into the irrigation canal
3. Migrating fish are not delayed in or by the fish screening facility.
4. Fish are not subjected to increased predation by the presence or operation of the screening facility.
5. Fish are protected during all possible screen operating scenarios, including periods between scheduled maintenance.
The region has excellent criteria for protecting most fish at irrigation diversions. The challenges for the future include: providing complete protection for fish less than 40 mm in length, reduction of operation and maintenance expenses without sacrificing benefit to fish, and development and implementation of a monitoring program to ensure that operating facilities continue to meet design criteria.

Management implications
Unscreened and inadequately screened irrigation diversions, or poorly maintained screens facilities result in the loss of many juvenile salmon and steelhead that have survived the rigors of natural rearing only to be killed at the beginning of their journey to the ocean. Screening irrigation diversions has a high probability of reducing salmon and steelhead mortality and will require the use of all available resources for funding, design, construction and installation.
Project 8506200 has provided the region with the evaluations of installed screening facilities to ensure that the facilities are accomplishing the objectives for which they were designed and built. Monitoring of the screening facilities� compliance with the design and maintenance criteria is key to measure 7.11B of meeting its objective of protecting juvenile salmon and steelhead during their migration to the ocean.

Specific measureable objectives
There were three specific measurable objectives for Project 8506200:
1. Provide fisheries and hydrological evaluations of new screens as they are installed.
2. Provide a laboratory facility for testing proposed changes to facility components (e.g., new bottom seals, forebay configurations, screen mesh size).
3. Provide on site monitoring of operating screens.
All these tasks are coordinated with BPA technical staff and address current and projected needs of the staff at the Washington State Department of Fish and Wildlife, U.S. Bureau of Reclamation, Yakima Indian Nation, and National Marine Fisheries Service.

Testable hypothesis
The testable hypothesis for Project 8506200 is fish screening facilities can be designed, constructed, operated and maintained to protect fish that are diverted into irrigation canals.
Underlying Assumptions
The underlying assumptions for testing this hypothesis are:
1. Fish are not killed or injured as they are diverted from the irrigation canal back to the river.
2. Fish can not pass downstream of the facility into the irrigation canal
3. Migrating fish are not delayed in or by the fish screening facility.
4. Fish are not subjected to increased predation by the presence or operation of the screening facility.
5. Fish are protected during all possible screen operating scenarios, including periods between scheduled maintenance.

Underlying assumptions or critical constraints

Methods
The methods used to meet the objectives for Project 8506200 are:
1. Conduct fisheries and hydrological evaluations of the newly installed fish screening facilities.
2. Conduct fisheries and hydrological evaluations at established fish screening facilities to monitoring operational changes and maintenance effectiveness.
3. Establish and maintain fish screening facilities at the Pacific Northwest National Laboratory in Richland, Washington to provide at controlled setting for testing design and operational changes to screen facilities.

Biological need
During the last 50 years, state and federal entities have initiated water screening diversion programs throughout the Columbia River basin. Hundreds of screens have been installed at withdrawals from important fish producing streams. Unfortunately, salmon and steelhead are still being lost in diversions throughout the basin. A large number of diversions remain unscreened.
The region, through the cooperation of the state fisheries agencies and the National Marine Fisheries Service, has developed and maintained design, construction, operational, and maintenance criteria to provide fish screening facilities that protect fish. Screens are placed in a harsh environment. Water quality changes erode the metal components of the screen facilities. Ice and large debris block and stress screen structures. Sediments change flow patterns at the screen facilities. The need to evaluate screens after they are constructed and after they have been in operation needs to continue to ensure that the criteria are being met and that fish are being protected.
Additionally, new challenges continue to appear as new screens are put into operation. In resent years, we have demonstrated that fish that are less than 40 mm in length are not always protected by the current design and operational criteria. New screen mesh sizes need to be tested. New technologies, e.g., infrasound need to be tested for application at screen facilities.

Critical uncertainties
Uncertainties underlie the assumptions for testing the hypothesis that fish screening facilities can be designed, constructed, operated and maintained to protect fish that are diverted into irrigation canals. The critical uncertainties are:
1. Can fish be killed or injured as they are diverted from the irrigation canal back to the river?
2. Can fish pass downstream of the facility into the irrigation canal?
3. Are migrating fish delayed in or by the fish screening facility?
4. Are fish subjected to increased predation by the presence or operation of the screening facility?
5. Are fish protected during all possible screen operating scenarios, including periods between scheduled maintenance?

Summary of expected outcome
The state and federal entities that are designing, constructing, operating and maintaining fish screening facilities throughout the basin need to know which screens are meeting the criteria for protecting salmon and steelhead. The evaluations will provide information to answer questions about:
1. injury and mortality rates at existing screens,
2. passage failures for screens, screen seals, and operational procedures,
3. possibility of migration delays,
4. incidence of increased predation at screen facilities
5. operational changes that might adversely affect fish at screening facilities,
6. the potential for application of new technologies at screen facilities, and
7. adequacy of maintenance procedures at screens.

Dependencies/opportunities for cooperation
Project staff regularly work with Washington State Department of Fish and Wildlife, the Idaho Fish and Game, the U.S. Bureau of Reclamation, and the National Marine Fisheries Service. Project work also requires coordination with the irrigation districts of the Yakima Basin and the Yakama Indian Nation.

Project 8506200 is related to screen improvement projects throughout the basin. These include: 7.10A.3 (Fisheries Managers maintenance of a prioritized list of tributary screening and passage facilities), 7.10A.4 (National Marine Fisheries Service, Working Oversight Committee, Appropriate Technical Work Groups and Bonneville identification of resources needed to accomplish screening and passage and monitoring and evaluation plans), 7.10A.5 (Bureau of Land Management, Idaho and Oregon/Washington Offices; U.S. Forest Service Regions 1,4,6; and Bureau of Reclamation, Pacific Northwest Region requirements that existing and new water use authorizations have functional fish screens and other passage facilities), 7.10A.6 (Corps of Engineers inspection of underwater diversions), 7.10A.7 (Idaho, Oregon, Washington requirements that installation, operation, and maintenance of fish screens are in compliance with state laws), 7.10.D (Bonneville�s evaluation of Dryden Dam screens), and 7.11 (Improvement of irrigation diversions in the Yakima River basin).

Risks
The risks associated with project 8506200 are inherit in the underlying assumptions:
1. Fish are not killed or injured as they are diverted from the irrigation canal back to the river.
2. Fish can not pass downstream of the facility into the irrigation canal
3. Migrating fish are not delayed in or by the fish screening facility.
4. Fish are not subjected to increased predation by the presence or operation of the screening facility.
5. Fish are protected during all possible screen operating scenarios, including periods between scheduled maintenance.
If any of these assumptions about the screens that are being designed, constructed, operated, and maintained in the Columbia River basin are false, salmon and steelhead will not be protected. Project 8506200 objectives are to determine that fish are being protected at irrigation diversions.

Monitoring activity
For monitoring and evaluation during project 8506200, we assessed whether we were on schedule and meeting the deliverables. For monitoring and evaluation, after the screening of all the irrigation diversion is complete, the region could assess whether the fish are being protected at the screening facilities.
