The Chesapeake Bay Watershed stretches across more than 64,000 square miles in West Virginia, Pennsylvania, Delaware, Maryland, New York, Virginia, and D.C.  

The streams born in our mountains flow into major river systems that provide drinking water for much of the Mid-Atlantic. In fact, the two main tributaries of the Bay begin in West Virginia: the headwaters of the Potomac and James River both begin in the Mountain State.

The West Virginia portion of the Chesapeake Bay Watershed, about 14% of our land mass, includes Berkeley, Grant, Hampshire, Hardy, Jefferson, Mineral, Morgan, Pendleton, and small portions of Preston, Tucker, and Monroe counties.
