199302900 - Survival Estimates for the Passage of Juvenile Salmonids Through Snake and Columbia River Dams and Reservoirs

Sponsor: Northwest Fisheries Science Center

Budgets: FY07: $1,688,376 | FY08: $1,739,026 | FY09: $1,791,197

Short description: Provide precise measurements of survival of juvenile salmon as they migrate through dams and reservoirs in the Snake and Columbia Rivers and relate to adult returns.

Final Council recommendation (Nov 2006)

Funding category: Expense

Recommended budgets: FY07: $1,688,376 | FY08: $1,739,026 | FY09: $1,791,197


ISRP final recommendation: Fundable


The size and complexity of the project warrant periodic special review. The region is again advised to think about the future of this research and monitoring effort, which is a cornerstone of salmon evaluations in the mainstem of the lower Snake and Columbia rivers. This is a very well prepared proposal that rates high marks for all ISRP review criteria. The ISRP's positive comments on the FY 2000 and FY2003 proposals remain germane. The excellent publication record continues. New for the project since the last review is the evaluation of adult returns of PIT-tagged fish to further understand relationships among adult survival, juvenile survival, travel time, migration timing, and other factors, such as numbers of bypasses or passage routes that juveniles encountered during their downstream migration. This is a natural and worthwhile evolution of project objectives and will continue to keep this project a cornerstone of salmon survival evaluations in the mainstem.

State/province recommendation: MS: Core Program

Comment: This project is coordinated with project number 19960200. The pair-trawl portion of this project takes place in the Lower Columbia River and helps document survival of PIT-tagged smolt through Bonneville Dam and the estuary.
