A floating 1,000-ton collector designed by PSE was constructed to contain fish handling equipment to route the downstream migrant  fish into a hopper to be trucked around the dam and released downstream below the dam. Work consisted of a screening system to separate the fish from the turbine intake penstock water so they could avoid the turbines.

Electrical work included a 15KV power underground duct bank to 15KV disconnect on  the dam extended to two special 15KV cables draped under water to two control buildings on the barge containing the 500KVA 15KV to 480V substations and motor control centers. Pump motors to furnish attraction water for the fish were (4) 100HP and (4) 30HP.
