This dataset is a list of U.S. Existing Non-powered Dams (NPD) with hydropower potential greater than 1MW and consists of geo-referenced digital data and associated attributes. The computed potential hydropower energy and capacity are estimates based on non-directly measured flow and head, and hence do not represent the actual numbers for engineering design. This resource assessment is not intended to provide economic feasibility level studies at each individual site. It will be the users' sole responsibility to determine whether if any site is worthy for further development.
