1 Washington’s Lower Snake River Compensation Plan Steelhead Program – A retrospective and program adaptive management overview Mark Schuck and Joe Bumgarner Snake River Lab, Dayton, WA

2 Funding provided by:

3 Program Origin The Lyons Ferry Hatchery program was authorized by the Water Resources Development Act of 1976 (PL 94-587) to offset losses caused by the construction and operation of the four Lower Snake River dam and navigation lock projects. The Lyons Ferry Hatchery program was authorized by the Water Resources Development Act of 1976 (PL 94-587) to offset losses caused by the construction and operation of the four Lower Snake River dam and navigation lock projects. Facilities were constructed by the USACOE Facilities were constructed by the USACOE Also constructed hatcheries in Oregon and Idaho Also constructed hatcheries in Oregon and Idaho

5 Lower Snake River Fish and Wildlife Compensation Plan - 1976 Fall Chinook Fall Chinook –18,300 adults/year Tucannon Spring Chinook Tucannon Spring Chinook –1,132 adults/year to the river Summer Steelhead Summer Steelhead –4,656 adults/year to project rivers In-place and in-kind In-place and in-kind Resident fish – fishing opportunity Resident fish – fishing opportunity –67,500 angler days

9 Production + Evaluation Monitor the success of LFH in meeting LSRCP compensation goals and identify production adjustments to accomplish that objective. Monitor the success of LFH in meeting LSRCP compensation goals and identify production adjustments to accomplish that objective. –Fisheries, SAR, and Abundance were primary performance metrics »Size & time of release, stock differences, acclimation, genetics, morphometrics, transportation, effects on natural populations, etc. It was envisioned as applied management (adaptive) of the program to ensure success. Work completed was therefore often reactive as conditions, study results or Management emphasis changed It was envisioned as applied management (adaptive) of the program to ensure success.

16 Management Paradigm Changes ESA listing for Snake River steelhead by 1999 – all Snake anadromous ESA listed. ESA listing for Snake River steelhead by 1999 – all Snake anadromous ESA listed. –Concern about excessive hatchery returns Washington Wild Salmonid Policy Washington Wild Salmonid Policy Hatcheries come under scrutiny Hatcheries come under scrutiny –Hatchery/Wild Interactions –Can supplementation work? –Goals appropriate?

17 Program Changes Release Locations altered or discontinued Release Locations altered or discontinued –Adoption of wild management rivers (Asotin)

23 New Broodstocks – Test Programs Tucannon River Tucannon River Long-Term Intent: Supplementation/Mitigation »50,000 smolts annually, assess program success on adult returns to project area (PIT Tags). Touchet River Touchet River Long-Term Intent: Mitigation »50,000 smolts annually, assess program success on adult returns to project area (PIT Tags).

31 Adult Returns to Project Area LSRCP Goal = 4,656

32 Current & Potential Future Changes Tucannon Endemic Implementation - 2010 Tucannon Endemic Implementation - 2010 Monitor adult returns and straying for future production level changes Monitor adult returns and straying for future production level changes –Lower Snake River small stream tributary monitoring - TRT assignment to populations (Tucannon or Asotin?) Consolidation of Mitigation Stocks Consolidation of Mitigation Stocks

33 Potential Future Changes Touchet Endemic – Policy Decision Required Touchet Endemic – Policy Decision Required Establishing reference populations to determine hatchery effects Establishing reference populations to determine hatchery effects Can a large hatchery steelhead mitigation program be operated in this ESA environment? Can a large hatchery steelhead mitigation program be operated in this ESA environment? –Biological or social decision? –Where to fisheries fit in?

34 Questions

35 Artificial Production Policy: Promote the achievement of the natural production policy and provide fishery-related benefits by implementing artificial production programs as a component of a comprehensive habitat, hydro, harvest, and hatchery strategy, and by assuring artificial production programs meet the following characteristics: –Conservation Programs. Provide a net aggregate benefit to the diversity, spatial structure, productivity, and abundance of the target wild stock. –Harvest Programs. Enhance harvest opportunities in a manner consistent with watershed specific goals for wild stock management.
