Explanation:

The area is home to birds such as the large blue heron and the American plain eagle. The Potomac River has performed an essential part in American history. For instance, America's first president, George Washington, lived for many years along the Potomac in Virginia. The Ohio River, which flows westward from Pittsburgh, Pennsylvania, to Cairo, Illinois, is the biggest river, by volume, of the Mississippi River in the United States. At the junction, Ohio is considerably bigger than the Mississippi and, thus, is hydrologically the mainstream of the entire river system.  Hoped this helped!
