U.S. Fish & Wildlife ServiceThis is the national compilation dataset of dams for the United States, including Puerto Rico and the US Virgin Islands. Updated 6/2024 This dataset feeds the National Aquatic Barrier Prioritization Tool at aquaticbarriers.org. This dataset includes large, regulated dams, small dams, unregulated dams, diversion dams, farm ponds, and low head dams. It was compiled from multiple sources using the national inventory of dams as a baseline. In addition to state and local datasets, national barrier datasets used in this inventory include the National Inventory of Dams , USGS Waterfalls of the Conterminous U.S. , and USGS Database of Stream Crossings in the U.S. Barriers are snapped to aquatic networks derived from the USGS High Resolution National Hydrography Dataset supplemented with additional information from the National Wetlands Inventory . Along with national data sources, several other regional and state efforts to collect barrier data were included in this inventory and are regularly updated within.
