Learning from Elwha: Mistakes of the Past are Lessons for the Future

“This weekend was a big milestone for the environment. The Department of the Interior officially began the nation’s largest river restoration project on the Elwha River in Washington’s Olympic National Park with the removal of the Glines Canyon and Elwha dams. When the dams on the Elwha River were created 100 years ago, its builders cut corners by neither building fish passages nor securing the dams to bedrock, which caused significant long term damage to the surrounding ecosystems, from the river to the estuary to the coast.

“The Elwha River Restoration Project is of great interest to active members of the conservation and fishery communities and local residents who have been advocating for the dam’s removal for many years. Not only will the dam removal provide substantial economic benefit, the environmental impact of removing it is profound. Sediment will be redistributed, waterways will be restored, and five salmon species are expected to return to their natural migration route that has been dormant since the dams were erected in 1911. The project also provides a tremendous educational opportunity for the next generation to learn from the past by providing a clear picture of how our actions impact the environment.”
