The last remnants of the Elwha Dam have been removed.
Contractors started removing the dam back in September. About two weeks ago, contractors removed the last piece of the dam from the Elwha River.
The river, which is in the Olympic National Park, was once home to all five species of Pacific Salmon. Environmentalists hope the removal of the dam will restore salmon runs and their natural habitat and attract animals who feed on the fish, like Golden Eagles.
The Elwha Dam was built in 1910. This has been the largest dam removal project in U.S. history.
