- Abstract:
- Impoundments on the Columbia, Snake and Clearwater rivers have strong effects on the environment encountered by adult salmonids as they migrate upstream. Reservoirs influence seasonal temperature regimes and spatial heterogeneity in temperature, key factors affecting salmonid behavior. We hypothesized that temperature gradients in fish ladders caused by thermal layering in reservoirs and dam forebays represent potential thermal barriers impeding passage of adult salmonids. As a preliminary step in quantifying the biological effects of ladder temperature gradients on adult salmonids, we examined associations between fish passage behaviors and the difference between fish ladder exit and transition pool temperatures (ΔT) at the time of the first detection of fish at the base of fishways. Study sites included McNary Dam and the four lower Snake River dams and this report includes data collected from 2000 to 2003.
