Abstract:
Correlations between lower Columbia River water temperatures and run timing, migration behavior, and tributary use by fall Chinook salmon Oncorhynchus tshawytscha were studied using historic counts and radio telemetry data. Over the past 70 years, mean August and September water temperatures recorded at Bonneville Dam have increased, often exceeding the estimated optimal migration temperature for fall Chinook salmon. We found median run passage dates from historic fall chinook count data at Bonneville, The Dalles and McNary dams were positively correlated with mean August water temperatures at Bonneville Dam, suggesting later adult migration timing in warm years.
