Description:

In 1999, we conducted an initial reconnaissance-level study to determine if the rebuilt system components provided safe juvenile passage conditions. In 2000, we completed a second, more thorough evaluation of the completed system. Major objectives of the studies were to determine detection and separation efficiencies, assess physical effects, and evaluate passage timing ofjuvenile salmonids. We conducted tests using juvenile yearling and subyearling chinook salmon Oncorhynchus tshawytscha, juvenile steelhead O. mykiss, and juvenile sockeye salmon O. nerka. Test fish were obtained directly from hatcheries or from juvenile fish-monitoring facilities (river-run test fish).
