Mathematical models for fish diversion systems based on fish behavior in conjunction with diversion system structural and hydraulic properties are developed. Guidance efficiency is described in terms of: the ratio of flow to swimming velocity, a ratio of bypass system dimension to a measure of fish shcool size, and a ratio of the distance fish first respond to a bypass system to the school dimension. Models for system efficiency are presented for diversion from a pump intake using a stimulus such as a strobe light and guidance efficiency of a submersible screen at a hydroelectric dam. The models illustrate what combinations of parameters may produce high guidance efficiency and help identify where additional studies are required.
