This lesson focuses on the impacts that the building of the two dams on the Elwha River had on anadromous fish species, including the loss of 70 miles of river habitat for migrating fish, the effects of sediment loss on spawning grounds downstream, and general habitat degradation downstream. Learn about pre-dam conditions both in-river and in the surrounding terrestrial environment. Then hear the story of Thomas Aldwell, the entrepreneur who built the first dam and refused to accommodate fish. Finally, discuss the political and environmental conditions that led to the decision to remove the dams.
