200755300 - Using acoustic telemetry to evaluate the behavior, habitat use, and survival of tagged juvenile salmonids in the John Day Reservoir

Sponsor: US Geological Survey - Cook

Short description: Large numbers of tagged juvenile salmonids are being released as part of behavior and survival research at mainstem dams. We propose to assess the feasibility of extending the use of these fish to better assess reservoir habitat use,behavior,and survival

Location: Mainstem/Systemwide province, John Day subbasin

Budgets: FY08: $844,848 | FY09: $132,487

Primary species:
Anadromous: Chinook: Mid-Columbia River Spring ESU
Anadromous: Chinook: Snake River Fall ESU (threatened)
Anadromous: Chinook: Snake River Spring/Summer ESU (threatened)
Anadromous: Chinook: Upper Columbia River Spring ESU (endangered)
Anadromous: Chinook: Upper Columbia River Summer/Fall ESU


ObjectiveDescriptionSubbasin planStrategies
Improve juvenile passage conditions The construction of the hydropower system turned the river into a series of reservoirs, which has greatly extended the juvenile migration period. Juvenile steelhead migrate through the area throughout the spring and early summer; juvenile coho in the spring; and fall chinook in late spring and late summer. Lower Middle Columbia
Restore normative hydrograph and improve migration Reduced travel time will improve survival and subsequent adult returns. Flow augmentation can increase water velocities. Alternative flood control strategies can helpful recapture the historical timing of flow. Increased spill diverts fish from the turbines and increases survival. Lower Middle Columbia
