Service Description: The Watershed Boundary Dataset (WBD) maps the full areal extent of surface water drainage for the U.S. using a hierarchical system of nesting hydrologic units at various scales, each with an assigned hydrologic unit code (HUC). HUCs are delineated and georeferenced to U.S. Geological Survey (USGS) 1:24,000 scale topographic base maps according to compilation criteria monitored by the national Subcommittee on Spatial Water Data.
The EPA and USGS have incorporated WBD into their NHDPlusV2 dataset that integrates useful features from the National Hydrography Dataset (NHD), the National Elevation Dataset (NED), and the Watershed Boundary Dataset (WBD). These datasets are continually updated. The watershed boundaries data found in EnviroAtlas were updated in a WBD Snapshot in April 2015 to ensure that recent HUC boundaries are available in EnviroAtlas.
This dataset was download from EPA’s EnviroAtlas.
