Title: Evaluation of Fall Chinook and Chum Salmon below Bonneville, The Dalles, John Day and McNary Dams; 1998-1999 Annual Report.

Abstract

This report describes work conducted by the Oregon Department of Fish and Wildlife (ODFW) and the Washington Department of Fish and Wildlife (WDFW) from 1 October 1998 to 30 September 1999. The work is part of studies to evaluate spawning of fall chinook salmon (Oncorhynchus tshawytscha) and chum salmon (O. keta) below the four lowermost Columbia River dams under the Bonneville Power Administration's Project 99-003. The purpose of this project is twofold: (1) Document the existence of fall chinook and chum populations spawning below Bonneville Dam (river mile (RM) 145), The Dalles Dam (RM 192), John Day Dam (RM 216), and McNary Dam (RM 292) (Figure 1) and estimate the size of these populations; and (2) Profile stocks for important population characteristics; including spawning time, genetic make-up, emergence timing, migration size and timing, and juvenile to adult survival rates. Specific tasks conducted by ODFW and WDFW during this period were: (1) Documentation of fall chinook and chum spawning below Bonneville, The Dalles, John Day and McNary dams using on-water observations; (2) Collection of biological data to profile stocks in areas described in Task 1; (3) Determination of spawning population estimates and age composition, average size at return, and sex ratiosmore » in order to profile stocks in areas described in Task 1; (4) Collection of data to determine stock origin of adult salmon found in areas described in Task 1; (5) Determination of possible stock origins of adult salmon found in areas described in Task 1 using tag rates based on coded-wire tag recoveries and genetic baseline analysis; (6) Determination of emergence timing and hatching rate of juvenile fall chinook and chum below Bonneville Dam; (7) Determination of migration time and size for juvenile fall chinook and chum rearing in the area described in Task 6; (8) Investigation of feasibility of determining stock composition of juvenile fall chinook and chum rearing in the area described in Task 6; (9) Documentation of stranding and entrapment in low-lying areas of juvenile fall chinook and chum rearing in the area described in Task 6; and (10) Investigation of feasibility of coded-wire tagging juvenile fall chinook captured in the area described in Task 6 to determine juvenile to adult survival rate.« less
