Description:Since 1975, the National Marine Fisheries Service (NMFS), under contract to the U.S. Army Corps of Engineers (CofE), has been conducting research to develop an improved fish protection system for use at Bonneville Dam, McNary Dam, and other CofE dams on the main stem of the Columbia and Snake Rivers. Part of the research objectives called for developing a less expensive (passive) screening system (bar screen) that could be substituted for the submersible traveling screen (STS) presently used to guide fish (mainly Pacific salmon, Oncorhynchus spp., and steelhead, Salmo gairdneri), out of turbine intakes at hydroelectric dams (Fig. 1) (Long and Krcma 1969; Farr 197
