Abstract: The necessity for providing fish passage facilities at both natural and man-made barriers is increasing. Alienation of upstream fish habitat by further development of hydroelectric power as well as making new habitat available particularly through salmonid enhancement projects, provide the major arenas for future fishway installation. Prior to the installation of any permanent fish passage facility that is new in concept, experimental evaluation should be carried out. It must be known whether the structure allows passage of the desired species in adequate numbers over a wide range of discharge conditions. In this project, a spiral type fishway, manufactured by the Aeroceanics Fishway Corporation, was experimentally evaluated with respect to passage of small (ave. 20.6 cm), adult kokanee salmon (Oncorhynchus nerka). Primary objectives of this project were to determine (1) how far fish could ascend the fishway and at what rate and speed, (2) if there were any effects of fish length, sex or maturation level on p
