Effects of Flow on the Migratory Behavior and Survival of Juvenile Fall and Summer Chinook Salmon in John Day Reservoir, 1981 Annual Report of Research.
Research was conducted by NMFS in 1981 to define the effects of instream flows on the passage time, survival, and migrational behavior of 0-age chinook salmon in John Day Reservoir. Fourteen groups (74,683 fish) of marked 0-age chinook salmon were wire-tagged, branded, and released into the tailrace at McNary Dam, fourteen groups (13,746 fish) were branded and released into the reservoir at River Kilometer 375, and 34 groups (14,273) were branded and released into the reservoir at various other sites. More than 55,000 0-age chinook salmon were sampled at the John Day Dam airlift facility. This sample included 623 mark recoveries. Four hundred and eight (408) additional marks were recovered from purse seine samples taken at various sites throughout the reservoir. The average passage time of marked 0-age chinook salmon released in the McNary trailrace was 22 days in 1981. There was no statistically significant evidence to indicate that instream flows affected either the rate of movement or residence time of 0-age chinook salmon in John Day Reservoir in 1981. 7 references, 1 figure, 12 tables.
