The world’s biggest dam removal project — and the second-largest environmental restoration project in U.S. history — is in progress on the Elwha River on the Olympic Peninsula in Washington state.
The Elwha Dam and the Glines Canyon Dam blocking the Elwha River are coming down due to aging infrastructure and as part of an effort to restore fish runs. When the dams were built in the early 1900s to provide hydroelectric power to nearby residents, they were installed without a way for fish to pass. Ever since, prime habitat upstream on the Elwha has been inaccessible to salmon.
