Our Pacific Northwest crew mobilized at a hydroelectric facility to repair a fish guidance net at Upper Baker Dam. 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.

ROV stands for remotely operated vehicle. They are highly maneuverable unoccupied machines used to observe and work underwater, often in areas that are deemed too dangerous for commercial divers. ROV pilots can operate them from a nearby shore or boat.

Remotely operated vehicles are versatile tools commonly used in our industry to inspect, monitor underwater structures, and perform complex work tasks in depths divers cannot access. Although, more recreational ROVs are available with advancements in technology. These revolutionary machines are utilized by many industries to reduce costs to clients and keep divers safe in unknown or dangerous conditions.
