Washington’s Lower Snake River Compensation Plan Steelhead Program –
A retrospective and program adaptive management overview
Mark Schuck and Joe BumgarnerSnake River Lab, Dayton, WA
Funding provided by:
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.
Facilities were constructed by the USACOE Also constructed hatcheries in Oregon and
Idaho

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

Production + Evaluation 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

Management Paradigm Changes
ESA listing for Snake River steelhead by 1999 – all Snake anadromous ESA listed.– Concern about excessive hatchery returns
Washington Wild Salmonid Policy Hatcheries come under scrutiny
– Hatchery/Wild Interactions– Can supplementation work?– Goals appropriate?
Program Changes
Release Locations altered or discontinued– Adoption of wild management rivers (Asotin)

Current & Potential Future Changes
Tucannon Endemic Implementation - 2010
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
Potential Future Changes Touchet Endemic – Policy Decision
Required Establishing reference populations to
determine hatchery effects Can a large hatchery steelhead
mitigation program be operated in this ESA environment?– Biological or social decision?– Where to fisheries fit in?
Questions
Artificial ProductionPolicy: 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.
