Potomac; river, the largest in Maryland, heading in the southwestern part of the 
State, near Fairfax Stone, where it is known as the North Branch; thence it 
flows northeast as far as Cumberland, then turns to the southeast and is joined 
by the South Branch. Below the junction it flows northeast as far as Hancock, 
and then takes a southeast course again. At Harpers Ferry it is joined by the 
Shenandoah on the south and passes the Blue Ridge. Eighteen miles above 
Washington are the Great Falls, and below that a succession of rapids and falls 
extending to the District of Columbia, In this stretch it passes the fall line. 
Below Washington the course is southwest for 40 miles, when it again turns to 
the east and southeast and enters Chesapeake Bay at Point Lookout. Below 
Washington it is tidal, has little current, and forms an estuary. The entire 
drainage basin of the river is 14,479 square miles.
