A geospatial dataset depicting the flow of water across the Nation's landscapes and through the stream network. The NHDPlus HR was built using the National Hydrography Dataset High Resolution data at 1:24,000 scale or more detailed, the 10 meter 3D Elevation Program data, and the nationally complete Watershed Boundary Dataset.
