Final Council recommendation (Nov 2006)

Funding category: Expense

Recommended budgets: FY07: $779,586 | FY08: $779,586 | FY09: $779,586

Comment: Scope expansion not accepted. Budget at the FY 2006 level.

ISRP final recommendation: Fundable


This is an extremely well-prepared and well-documented proposal. The background on technical and scientific issues is thoroughly presented. The project history appears complete and identifies that management calls upon the project for information to support hydrosystem operations, and that system operation modifications are under consideration because of the products of the project. There is a clear statement of objectives with a well-established need. The rationale and significance are clearly identified. Information on chum and fall chinook spawning and adaptation to the hydrosystem is crucial to system modifications to accommodate fish. The data will undoubtedly lead to management that will provide persisting benefits. The project is directed by experienced personnel who have an appropriate mix of expertise. The methods employed are sound, usual practices in fisheries investigations with the exception of the DIDSON sonar, which is rather new. The correct population parameters are being measured. The proposed activities are well integrated with past work and other agency projects.

State/province recommendation: MS: Core Program

Review group: MSRT

Recommended budgets: FY07: $779,586 | FY08: $779,586 | FY09: $779,586

Comment: This project establishes operating criteria for maintaining flows below Bonneville for redd distribution. There was some discussion that USACE versus BPA responsibility should be visited for this project. Chum portion of the project is Core Program; some members of the MSRT felt that the fall Chinook portion may be High Priority. This project is coordinated with project number 200303800, evaluating mainstem spawning habitat in the Snake River.
