Conservationists can now point to the largest dam removal project in the U.S. as a success story. The ecosystem of Washington's Elwha River has been thriving since the removal of its hydroelectric dam system. Recent surveys show dramatic recovery, especially in the near shore at the river's mouth, where the flow of sediment has created favorable habitat for the salmon population. A new generation of salmon species, some of which are endangered, are now present in the river. Some hope that the restoration of the Elwha River will become a shining example for the removal of dams across the U.S.
