    摘要: This is a method, and apparatus for performing the method, by which artificial stream conditions are generated within the forebay of dams used for hydroelectric facilities. The method includes the introduction into the reservoir at the appropriate depth of an artificial stream condition to attract downstream migrating fish and to then divert them into a generally nonvisible (at its inception) conduit with a gradually reducing interior section until such time as the fish are brought into an increased stream flow from which they cannot retreat. The fish are then carried by conduit around or in other manner bypassing the dam and the electrical generating turbines or the like to a point downstream from the dam where they are released into the stream. The system is characterized by jets forming an appropriate artificial stream, an in-line high volume fish pump, a transparent collector area through which the artificially induced stream flows, and a gradually reducing interior section resulting in increased velocity of the artificial stream to the point where the downstream migrating fish cannot escape. Also incorporated are provisions for eliminating predators from the stream.
