Repairing Fish Guidance Nets at a Hydropower Dam

Posted by Lauren Collins, Senior Project Manager on January 20, 2023

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.
