Fig. 3. Project features at Lower Granite Dam on the Snake River, WA USA for 2000 and 2003 studies [A]. The Behavioral Guidance Structure (BGS) is intended to guide emigrants to the Surface Bypass Collector (SBC) and occlude them from the 3 turbine intakes nearest the shore. In 2003, a Removable Spillway Weir (RSW) was deployed in the spillbay nearest the powerhouse in lieu of the SBC; the BGS was also removed. Acoustic-tag emigrant track (green in [B]) provided by U.S. Geological Survey (Cash et al., 2002). CFD model depiction of forebay hydrodynamic pattern for [B], [C] and [D] in Fig. 5a.
