The Potomac River is one of the largest Atlantic Coast rivers and a major tributary of the Chesapeake Bay. The Potomac River watershed covers four states and the District of Columbia.
The river originates from two sources. The source of the North Branch begins at the junction of Grant, Tucker, Preston counties in West Virginia while the South Branch rises in Highland County, Virginia.
Major tributaries of the Potomac include the Anacostia River, Antietam Creek, Cacapon River, Catoctin Creek, Conocoheague Creek, Monocacy River, Occoquan River, Savage River, Senaca Creek, and Shenandoah River.
Beginning as small mountain streams, the river gains strength and size as it flows across its path. The Potomac, the river grows to 11 statute miles wide as it flows into the Chesapeake Bay between Point Lookout, Maryland and Smith Point.
