Layer: NHD Major Waterbodies (ID: 16)

Name: NHD Major Waterbodies

Display Field: GNIS_Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This statewide feature class is a merge of two National Hydrography Dataset (NHD) layers: MajorNHDArea and MajorNHDWaterbody. Detailed information regarding the merge process can be found at Instructions  for WSDOT NHD data_2018_01_16.docx.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. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) 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. Best available data acquired from Ecology 12/2020.
