Quinault NFH Fish Exclusion Barrier Environmental Assessment

Stalks

PROJECT OVERVIEW: The Quinault National Fish Hatchery electric fish barrier is not currently functioning as designed. The U.S. Fish and Wildlife Service is overseeing the construction of a new fish exclusion barrier at Quinault NFH in Grays Harbor County, Washington. The Project will maintain the functionality of the hatchery by replacing the existing weir with a velocity barrier (consisting of an Obermeyer Weir gate system), replacing the existing electric weir control building, modifying riprap and an access road, and adding a fish bypass ladder.


Additionally, the Project includes routine maintenance activities consisting of cleaning water intakes, and removing woody debris and gravel buildup around the weir, and use of a construction staging area.
