Monitoring and Evaluation of Yearling Fall Chinook Salmon Released Upstream of Lower
Granite Dam
Project Goal
The goal of this project is to monitor and evaluate health and condition, post-release survival and behavior and adult returns of yearling and subyearling fall chinook salmon released from the fall chinook acclimation (FCAP) facilities upstream of Lower Granite Dam and feedback to co-managers to provide adaptive management opportunities.

Objectives Document health, condition and tag/mark retention of yearling fall chinook salmon at the FCAP facilities Determine post-release behavior, outmigration characteristics, and survival of fall chinook salmon released from the FCAP facilities
Document fall chinook salmon spawner abundance and distribution
Determine smolt-to-adult survival of fall chinook salmon released from the FCAP facilities
Participate in local and regional management planning, coordinate activities and share information
Feedback results to co-managers for adaptive management opportunities

Estimated Contributions of Fall ChinookAdult Returns to Lower Granite Dam, 1975-2003
Estimated survival rates of yearling fall chinook from the FCAP facilities in 1998-2003 range from 74% - 97% to Lower Granite Dam and 38% - 84% to McNary Dam.
Determined post-release characteristics such as migration rate and arrival timing to Lower Snake and Columbia River dams.
Conduct mark retention quality control sampling on yearlings (CWT, AD, VIE) and subyearlings (CWT).
Compiled health assessment data in cooperation with the Idaho Fish Health Center.
Annually submit CWT release data to RMIS database.
Assisted project 199801003 to monitor radio tagged adult fall chinook allowing description of migration patterns and distribution above Lower Granite Dam.
Assisted in conducting fall chinook spawning ground surveys in the Clearwater and Salmon River basins, 1999-2000.
Began conducting spawning ground surveys on Grande Ronde and Imnaha Rivers in 2003. Conduct spawning ground surveys on Salmon River in cooperation with project 198303500 and the BLM.
Taking lead in drafting of Snake River Fall Chinook M&E Plan. Led co-managers in negotiating and drafting SRFCS marking plan, which was revised through the US v. Oregon proceedings.
