Results of accelerated laboratory and field experiments to investigate problems of anadromous fish passage at high dams are summarized. Studies were made on: the passage of adult and juvenile fish through large, medium, and small impoundments; design and operation of adult fish-passage facilities at dams; mortalities of juvenile fish passing through turbines and methods of reducing losses; collection of juvenile fish from rivers, streams, and reservoirs; transportation of juvenile fish; and the effect of the changing environment on passage and survival. Publications by the staff are listed.
