Fish like alewives, historically essential to the ocean food chain and heretofore threatened, have shown almost instant response to the restoration of the natural passage where once a dam intervened, a natural renewal so essential to their health and proliferation. But what about the dams remaining?
Communities nationwide are benefiting from efforts to removed unsafe, outdated dams and restore river health. In the U.S., more than 1,100 dams that have outlived their usefulness have been taken down over the past 100 years. The United States is the global leader in river restoration through dam removal.
