Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.These data were further processed by the Business Innovation and Technology (BIT) Division GIS Section to isolate HU8 watersheds adjacent to Jefferson County from the Watershed Boundary Dataset (WBD). Data Type: Static. Vintage: 2025 from the National Hydrography Dataset (NHD) Watershed Boundary Dataset (WBD). Data are projected in WGS 1984 Web Mercator (auxiliary sphere).
