Why Look Up Dams Near You?
Over 91,678 dams exist across the United States, and 16,265 of them are classified as high hazard — meaning failure would probably cause loss of human life. Many people live downstream of high hazard dams without knowing it.
Understanding which dams are near your home is important for:
