About
Witness nature's remarkable comeback at the Elwha Dam site, a testament to ecological restoration in Washington's Olympic National Park. Once home to two massive dams, this area now showcases a free-flowing river, reclaiming its ancestral path and revitalizing a vibrant ecosystem. Visitors can explore the landscape transformed by dam removal, observe returning wildlife, and learn about the monumental effort to bring the Elwha River back to life.
The Elwha Valley offers a profound experience for nature lovers and those interested in conservation. Key highlights include the Glines Canyon Spillway Overlook, where you can gaze into the dramatic canyon carved by the re-energized river and see interpretive displays detailing the dam removal. The Elwha Dam Interpretive Site provides historical context and showcases the profound changes to the river. Numerous hiking trails wind through old-growth forests and along the riverbanks, offering opportunities to spot diverse wildlife.
A visit to the Elwha Dam site is a journey through a living laboratory, where the power of nature's resilience is on full display. It's a memorable destination that inspires hope and offers a unique perspective on human impact and environmental recovery, inviting contemplation on the interconnectedness of rivers, forests, and wildlife.

The Elwha River was historically a vibrant ecosystem, known for its abundant salmon runs that sustained the Lower Elwha Klallam Tribe for millennia. However, this changed with the construction of two hydroelectric dams in the early 20th century: the Elwha Dam, completed in 1913, and the Glines Canyon Dam, finished in 1927. These dams severely impeded fish migration, altered the river's natural sediment flow, and flooded tribal lands, leading to a drastic decline in salmon populations and ecological degradation. Decades of advocacy culminated in the Elwha River Ecosystem and Fisheries Restoration Act of 1992, authorizing the removal of the dams to restore the river to its natural state. The removal process, one of the largest dam removal projects in U.S. history, began with the Elwha Dam in 2011, completed by March 2012, followed by the Glines Canyon Dam, which was fully removed by August 2014. This ambitious project allowed the Elwha River to flow freely from its headwaters in the Olympic Mountains to the Strait of Juan de Fuca for the first time in over a century, triggering a remarkable ecological recovery.
