Upper Baker Dam is 1 of 2 hydroelectric dams on Baker River, near Concrete, WA. The entire Baker River Hydroelectric Project covers nearly 300 square miles. Upper Baker Dam, a 312-foot-high concrete gravity dam completed in 1959, has a floating surface collector system responsible for attracting and safely holding juvenile salmon for downstream transport around the dam. We supplied dive and topside support teams to assist the prime contractor with the recovery, disassembly, and installation of a new floatation collar on the existing barrier net. This is an essential repair to ensure safe fish passage around the dam.
