Elwha River

The Elwha River, located in Washington State, flows from the Olympic Mountains to the Strait of Juan de Fuca. It is notable for the Elwha Dam, which historically blocked salmon migration and altered the river's natural flow. In recent years, the dam was removed to restore the river's ecosystem, allowing fish like salmon to return and access spawning grounds. The river's restoration helps rebuild habitats, improve water quality, and promote biodiversity. The Elwha River serves as a key example of ecological recovery through dam removal and habitat restoration efforts.
