A large box net was constructed to capture migrating juvenile salmonids from turbine intake gatewells at hydroelectric dams. This net, operated at John Day Dam on the Columbia River, caught an average of 97.3% of the fall chinook salmon Oncorhynchus tshawytscha smolts present in the gatewells. The net is presently being used at other hydroelectric dams on the Columbia River system.
