198902401 - Evaluation of Juvenile Salmonid Outmigration and Survival in the Lower Umatilla River Basin

Sponsor: Oregon Department of Fish & Wildlife (ODFW)

Budgets: FY07: $549,550 | FY08: $398,065 | FY09: $416,435

Short description: Evaluate migration patterns, abundance & survival of hatchery & natural smolts in the Umatilla basin using PIT tags; install an adult ladder detector at TMFD; assess affects of river variables on fish migration; monitor life history characteristics.

Final Council recommendation (Nov 2006)

Funding category: Expense

Recommended budgets: FY07: $0 | FY08: $0 | FY09: $0


ISRP final recommendation: Fundable


This is a very thorough proposal with thorough methods that justify continuation. A history of the project to date was covered in detail in over ~ 20 pages. This project should assist in providing critical evaluation information to the set of Umatilla projects. And the ISRP encourages the proponent to publish results and observations in the formal fisheries literature. Monitoring and evaluation of smolt yields and survivals is the focus of the investigations. Some adaptive management is evident (e.g., steelhead releases moved to lower reaches), clearly indicating the benefits of this type of work. The project should provide data on egg-to-smolt survival and/or smolts-per-spawner as a function of spawner density to augment the information provided in table 4 (p 33). This is the key response variable in monitoring population dynamics and towards evaluation of management actions. There may also be a possibility, worth exploring, to collaborate with other tagging studies (e.g., POST), and to explore alternative methods for estimation of adults to relate smolt yields to spawner abundance more effectively. See ISRP comments on the “Umatilla Initiative” under proposal 198343600.

State/province recommendation: Fundable, but at a reduced level

Review group: OSPIT - Plateau

Recommended budgets: FY07: $306,235 | FY08: $306,235 | FY09: $306,235

Comment: OSPIT recommends holding project funding to FY06 levels and flatlined. OSPIT hopes to find greater synergies with the three M&E projects (199000500, 199000501 and 198902401) for other possible budget reductions.
