U.S. Fish & Wildlife ServiceThis dataset represents the Delaware River Watershed created by merging two hydrologic unit code (HUC) 6 watersheds from the complete digital hydrologic unit boundary layer of the Basin (6-digit) 3rd level for the entire United States. The source data consists of geo-referenced digital data and associated attributes created in accordance with the "Federal Guidelines, Requirements, and Procedures for the National Watershed Boundary Dataset; Chapter 3 of Section A, Federal Standards, Book 11, Collection and Delineation of Spatial Data; Techniques and Methods 11-A3" (04/01/2009). http://www.nrcs.usda.gov/wps/portal/nrcs/detail/national/water/watersheds/?cid=nrcs143_021630 . Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. The data are currently updated through the USGS National Hydrography Dataset (NHD) Program and replicated to NRCS twice per year.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/7d3ee2340b8046109f4c1b94b7f18f0e_0engU.S. Fish and Wildlife Service Open DataPublicDelaware River Watershed boundary, Northeast Region [United States]Web servicesUnited StatesLast Modified: 2012-10-18
