APRE Summary Program name: Summer Steelhead (LF)-Hatchery Subbasin: Walla Walla ESA status: Not listed and not a candidate for listing Co-operators Role U.S. Fish & Wildlife Service Lower Snake River Compensation PlanProgram Funding & Oversight Oregon Department of Fish & Wildlife Co-Manager Confederated Tribes of the Umatilla Indian Reservation Co-Manager Operator: WDFW Funding Source(s) Lower Snake River Compensation Plan Mitigation Funds- U.S. Fish & Wildlife Service Annual Operating Cost* $ 180,000 *Annual Operating Cost is reflected in dollars. The origin of this value is not consistent among programs, as it may reflect total facility costs or multiple programs for a given species. The purpose of this program is to contribute to: Harvest, as mitigation for: Hydro impacts (off-site mitigation for Snake R. production) and Habitat loss. This is a segregated program. Program description: Location Age Class Maximum Number Size (fpp) Release Date Stream Release Point (RKm) March 25-May 10 (Touchet Release) and April 15-25 (Walla Walla Release) Touchet River (acclimated) and Walla Walla River (direct release treatment) 87 (Touchet) and 56 (Walla Walla) Major Watershed Ecoprovince Eggs Unfed Fry Fry Fingerling Yearling 225,000 4 Walla Walla Columbia Plateau Comment: Brood stock is collected from adults returning to the Lyons Ferry Hatchery. Adults are held and spawned at the Lyons Ferry adult holding and spawning facility. Eggs are incubated at Lyons Ferry, and fish are reared at the Lyons Ferry Hatchery. Yearling fish are transported to the Walla Walla subbasin for release into the Touchet and Walla Walla Rivers. The fish are released into the Touchet river as a Dayton Acclimation & Volitional Release. Yearling fish are directly released into the Walla Walla River . Touchet Dayton Acclimation & Volitional Release In February, yearling fish are transported to Dayton Acclimation Pond off-stream of the Touchet River (~RKm 87) where they are fed and acclimated to Touchet River water. They are fed and volitional released over the period of March 25 through May 1. Walla Walla River Direct Release Fish are transported from Lyons Ferry and directly released to the Walla Walla River at RKm 56 during the period of April 15-25.

The adult returns from those releases were then used to create the LFH stock currently used. The LFH stock is considered an "A" run steelhead, typical of most Columbia River stocks. Status and goals for target stock: = Low = Medium = High Now 10-15 years 30-50 years Biological Significance Viability Habitat Hatchery program performance indicators for the target stock: Recruits per Spawner Smolt-to-Adult Survival Escapement and Hatchery Spawning Consistency of hatchery program with the goals for the target stock: The goal for this hatchery stock is to maintain its viability and provide harvest. The use of a segregated harvest program is consistent with this goal. The program is tailored to address and perform according to stipulations and objectives set forth in the Lower Snake River Compensation Plan for Lower Snake River hydroelectric projects and research/M&E activities. The Annual Lower Snake River Compensation Plan agreement sets forth specific program performance indicators (fish size & release numbers, survival, etc.) that are explicitly monitored and evaluated. The program is adaptively managed to adhere to stated program performance standards. Total Catch Guidelines for improving key operational elements to increase the likelihood of meeting goals for the target stock: Adult Holding Hatchery intake screening for the adult holding supply should comply with Integrated Hatchery Operations Team (IHOT) and National Marine Fisheries Service facility standards. Incubation Hatchery intake screening for the incubation water supply should comply with Integrated Hatchery Operations Team (IHOT) and National Marine Fisheries Service facility standards. Rearing Juvenile rearing density and loading guidelines used at the facility should be based on life-stage specific survival studies conducted on-site. Hatchery intake screening for the rearing water supply should comply with Integrated Hatchery Operations Team (IHOT) and National Marine Fisheries Service facility standards. Release Fish produced should be qualitatively similar to natural fish in growth rate. These recommendations represent an opportunity to improve key operational elements for this type of program. Detailed information on the benefits and risks of all operational phases as they affect the outcome of this program are available in APRE Report for Summer Steelhead (LF)-Hatchery in the Walla Walla Consistency of hatchery program with goals for other stocks: Hatchery fish may affect other stocks in several ways. Naturally spawning populations may be subject to genetic interactions through interbreeding. Ecological interactions through predation and competition may occur between the hatchery population and other populations, and natural populations may be incidentally harvested in fisheries targeting a more abundant hatchery stock. Abundant hatchery stocks may also mask the status of natural populations. Conversely an increase in the number of artificially produced fish may improve the ecological function of a watershed through their contribution of marine derived nutrients. A number of factors are known to affect the likelihood and severity of such interactions, among them the abundance of the hatchery population relative to other populations; the time, size and life stage at which hatchery fish are released; and the quantity and quality of habitat available to the co-mingled stocks. The table below lists the current status of some of the populations in the subbasin where the hatchery fish are released that might be vulnerable to these interactions. Stock Name Bull Trout- Natural Pacific Lamprey-Natural ESA Listing Threatened Not listed and not a candidate for listing Viability M L Biological Significance M H Additional reviewer comments: The program fish are marked at a 100% rate. Adult monitoring at the Dayton weir and stream surveys within the Walla Walla subbasin provide limited to monitor and control straying. Manager/operator response: Per CTUIR: Believe the release goal for the past few years has been 225K which is being further reduced to 185K in 2004. Would suggest splitting out the two release components in the “Program Description” table. Same general comment on inclusion of acclimation facility in facility locations. Appears “Additional Reviewers Comments” on the monitoring is incomplete or missing something.
