Juvenile fall chinook salmon, Oncorhynchus tshawytscha, were freeze-branded, coded-wire tagged, and released into the Columbia River in the tailrace below McNary Dam during the summers of 1981-1983. The objectives of the study were to examine the effects of river flow on the passage time and migrational behavior of the juveniles and to subsequently assess any relationship to adult survival. This report details adult recovery data to June 1987.
