Mud Mountain Fish Passage

The Mud Mountain Dam in Enumclaw, Washington was not meeting fish-passage needs. Construction on a new trap-and-haul fish passage facility began in 2018. The new design is anticipated to move 60,000 fish per day. This facility will allow endangered species such as Chinook Salmon, Bullhead and Steel Trout to travel up-river to breeding grounds. This will allow the populations of these critical species to grow and provide cascading ecological benefits as well as economic benefits to the fishing industry in Washington. This project will also help ensure Muckleshoot and Puyallup Tribes’ treaty rights to fish on the White River.
