Allegheny County Watershed Boundaries

This dataset demarcates the 52 isolated sub-Watersheds of Allegheny County that drain to single point on the main stem rivers. Created by 3 Rivers 2nd Nature based upon Allegheny County watershed file showing all tributaries of all streams. All tributatries draining to a single point on the river were joined as a single major stream system watershed for field measurement and analysis purposes.
