Glines Canyon Dam, built in 1927, is a convert|210|ft|m|0|adj=on high concrete arch dam that forms Lake Mills convert|13|mi|km|0 upstream from the Elwha River's mouth.

Lacking passage for migrating salmon, its construction blocked access by anadromous salmonids [harvnb|Grossman|2002|p=155] to the upper 38 miles (48 km) of mainstem habitat and more than convert|30|mi|km|0 of tributary habitat. The Elwha river watershed once supported salmon runs of more than 400,000 adult returns on more than 70 miles of river habitat. Today, less than 4,000 adult salmon return each year in only 4.9 miles of river.

The "Elwha River Ecosystem and Fisheries Restoration Act of 1992" authorized the US Federal Government to acquire the Glines Canyon hydroelectric power projects for decommissioning and demolition for habitat restoration.

The Elwha Ecosystem Restoration project has the dam slated for removal beginning in 2012. Once removed, the area that is currently under Lake Mills will be revegetated and its banks secured to prevent erosion and to speed up ecological restoration.
