• Description:
  The COE has proposed a juvenile fish bypass system for The Dalles Dam similar to those in use at other COE Columbia and Snake River projects. In 1985 and 1986, the National Marine Fisheries Service (NMFS) conducted research at The Dalles Dam to determine the potential fish guidance efficiency (FGE) for yearling chinook salmon (Oncorhynchus tshawytscha), sockeye salmon (O. nerka), and steelhead (O. mykiss) attainable with standard-length submersible traveling screens (STS) (Monk et al. 1986, 1987) . Additionally, the vertical distribution of fish entering the turbine intake was measured to determine theoretical fish guidance efficiency (TFGE, an estimate of the percentage of fish theoretically guidable based upon hydraulic model studies and the vertical distribution of fish).
