Name: Subregions (HUC4)

Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This data set is a complete digital hydrologic unit boundary layer to the SubRegion (4-digit) 2nd level for the entire United States. The intent of defining Hydrologic Units (HU) within the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. Hydrologic units are intended to be used as a tool for water-resource management and planning activities particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The WBD complements the National Hydrography Dataset (NHD) and supports numerous programmatic missions and activities including: watershed management, rehabilitation and enhancement, aquatic species conservation strategies, flood plain management and flood prevention, water-quality initiatives and programs, dam safety programs, fire assessment and management, resource inventory and assessment, water data analysis and water census. This data set was obtained from the source in June 2019.
