NJDEP Bureau of GISDrainage basins are delineated from 1:24,000-scale (7.5-minute) USGS quadrangles. The delineations have been developed for general purpose use by USGS District staff over the past 20 years. Arc and polygon attributes have been included in the coverage with basin names and ranks of divides, and 14-digit hydrologic unit codes. The New Jersey state boundary as originally defined in the USGS source coverage does not match that used by the NJDEP. Therefore the coverage was edited by the NJ Geological Survey to remove the USGS state boundary and insert the NJDEP state boundary, thus resolving most potential clipping errors. Note: Some information in this metadata describes the DEPHUC 14 coverage instead of the DEPHUC 11 because DEPHUC 14 is more detailed. Most processes and procedures used are identical for both coverages.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/02599a9424254a4ea33e689941559e3c_17engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublic11 Digit Hydrologic Unit Code delineations for New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2021-11-08
