Description:

Results of 1997 tests suggested mortality rates of about 13% for coho salmon (O. kisutch) and 8% for subyearling chinook salmon (O. tshawytscha) passing at 64% spill. In 1998, we expanded the research to include assessment of passage survival through the spillway at high spill (64% ofriver flow) and moderate spill (30% of river flow) and through the ice and trash sluiceway during daytime periods at moderate spill (30% of river flow).
