West Virginia Watersheds

What is a watershed? After you learn what a watershed is, It is important that you understand how to determine watershed boundaries and become familar with our state's topographic maps. 
West Virginia has 32 watersheds divided according to the USGS hydrologic unit codes (HUC) that contribute to the Chesapeake Bay and the Gulf of Mexico.  The waters west of the eastern continental divide flow into the Ohio River. The Ohio joins the Mississippi River at Cairo, IL. The Mississippi flows into the Gulf of Mexico at New Orleans, LA. The eastern continental divide changes the course of five of our eastern rivers towards the Potomac River. The Potomac enters the Chesapeake Bay southeast of Washington DC.  A few streams in the southeastern corner of the state flow towards the James River.  Use the tools below to learn more about your local, state and US watersheds.
