The removal of the Elwha Dams drained Lake Mills. One of the concerns was with the huge amount of sediment that had been trapped behind the dams and the impact that would have on the ecology downstream. A lot of careful planning has resulted in a rapid recovery … salmon and steelhead trout have already returned to the river. Not in the huge numbers that once were present … but quicker than many thought likely.
From the photos below (less than a mile below the upper dam), you can see that the river is now running clean and clear.
