Description:

This study addresses turbine survival issues described in the National Marine Fisheries Service (NMFS) biological opinion and NMFS salmon research plan and is part of the U.S. Army Corps of Engineers Turbine Survival Program. There were two objectives of this study. The first was an initial evaluation of the condition of fish exposed to the gatewell environment at an operating load above the 1% peak efficiency band (16,400 ft3 /sec). PIT tags were used for evaluations under this objective because of the number of fish required and the capability to recapture PIT-tagged fish at the juvenile fish facility. The second objective was a relative survival evaluation comparing survival of fish released at an operating load of 11,200 ft3 /sec (within 1% of peak efficiency) to fish released at an operating load of 16,400 ft3 /sec. This evaluation was conducted with surgically-implanted radio tags to minimize the number of fish required to obtain statistical precision.
