A method to align watersheds with the Watershed Boundary Dataset - Curtis Price

Abstract - The U.S. Geological Survey (USGS) has begun an effort to serve watershed boundaries for its continuous-record gages in alignment with the seamless, locally-reviewed Watershed Boundary Dataset (WBD) polygons. Because gage locations are not located exactly on WBD boundaries, a method was developed that, given a user-supplied watershed polygon and pour point, a) clips and conforms the input polygon to a WBD polygon boundary, b) merges any “upstream” WBD polygons, and c) recalculates area.
