National Hydrography Dataset

The National Hydrography Dataset (NHD) represents the water drainage network of the United States with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages.

Note – As of October 1, 2023, the NHD was retired. NHD data will continue to be available, but no longer maintained. The most current data will be available through the 3D Hydrography Program (3DHP).
