- Abstract:
- Passage rates and routes of adult Chinook and sockeye salmon and steelhead with radio transmitters were monitored at John Day Dam in 1997 with turbine 1 (south end of powerhouse) operated at two levels (100 and 150 MW ). A split-block experimental design was used to compare where fish approached and entered fishways, and mean and median times for fish to first approach and enter fishways when turbine 1 was operated at either of the two generation levels . Proportions of salmon and steelhead that approached and entered the south-shore fishway entrance and mean and median times for all three species to first approach and first enter fishways did not vary significantly in relation to turbine 1 operation. We conclude that operating turbine 1 at maximum capacity did not significantly affect passage for salmon and stee lhead at John Day Dam in 1997.
