Time lapse of two hydroelectric dams being torn down

posted by Jason Kottke   Jun 20, 2016

Two hydroelectric dams on the Elwha River in Washington were removed in order to restore the river’s ecosystem — in particular, the salmon habitat. It was the largest dam removal in the US history and, as the video explains, has been successful so far in attracting fish back to its waters. But for our purposes here today, the first 30 seconds shows how the dams were unbuilt and the rivers reshaped.
