The largest dam removal project in American history began in 2011 on the Elwha River on the Olympic Peninsula in Northwest Washington State. Since then two dams were removed, allowing the river to run free for the first time in over 100 years. The slides show what’s left of the Gline’s Canyon dam and Lake Mills that it backed up. Being freed, the river now runs naturally and you can see much of the debris that washed down from the lake when the dam was first breached. The later pictures show it in its more natural state. Several species of Wild Pacific Salmon have already found their way back up the river to their primordial spawning grounds.
