Elwha River dam removal (2011-2014)
The Elwha and Glines Canyon dams were removed from the Elwha River in Washington state, the largest dam removal project in US history at the time. The $325 million project restored 70 miles of salmon habitat.
Salmon returned to the river within months of dam removal. The river began carving a new channel through the former reservoir beds.
The Elwha became a model for dam removal projects worldwide, showing that rivers can recover quickly when dams are removed.
The Grand River project follows the Elwha model, using dam removal to restore natural river function and fish passage.
