Watersheds (HUC8)
This data set is a complete digital hydrologic unit boundary layer to the Subbasin (8-digit) 4th level for the entire United States. This data set 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.ncgc.nrcs.usda.gov/products/datasets/watershed/index.html . Polygons are attributed with hydrologic unit codes for 1st(Region), 2nd(Sub-Region), 3rd(Basin), and 4th(Sub-Basin) Hydrologic Unit Level codes, names, Sub-Basin acres and square miles.
