Image of the Week - Elwha River Dam Removal
In September 2011, the largest dam removal project in U.S. history began.
Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.
