NHDPlus High Resolution

USGS National Hydrography Dataset Plus High Resolution. 1:24,000-scale flowlines with network attributes for the United States.

NHD high-resolution flowlines combined with 3DEP elevation, giving flow direction, accumulation, catchments and value-added attributes for routing (upstream and downstream navigation, stream order). Distributed per 4-digit hydrologic unit. USGS is moving to the 3D Hydrography Program for new work.
