Exciting and dramatic changes have taken place in the Elwha River in the last two years with the removal of two dams. The Glines Canyon Dam (1927) and the Elwha Dam (1910) were removed to restore the watershed’s ecology unblocking passage for migratory salmon. Salmon have already begun to find their way up the newly freed river. Since the time of their building many things have changed about our understanding of river system ecology causing an ever-increasing movement to remove them. The Elwha River dam removal project is currently the largest one in history.
