Summary
[edit]DescriptionPotomac River, George Washington Memorial Parkway, Virginia (2847876128).jpg |
The Potomac River flows into the Chesapeake Bay, located along the mid-Atlantic coast of the United States. The river (main stem and North Branch) is approximately 405 miles (652 km) long, with a drainage area of about 14,700 square miles (38,000 km²). In terms of area, this makes the Potomac River the fourth largest river along the Atlantic coast of the United States and the 21st largest in the United States. Over 5 million people live within the Potomac watershed. The river forms part of the borders between Maryland and Washington, D.C., on the left descending bank and West Virginia and Virginia on the river's right descending bank. The majority of the lower Potomac River is part of the State of Maryland. en.wikipedia.org/wiki/Potomac_river en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
