Chattahoochee River, a river in the southeastern United States. The Chattahoochee's source is in the Blue Ridge Mountains in northeastern Georgia. From there the river flows south westward, past Atlanta, to the Alabama border. It then flows southward, forming part of the Georgia-Alabama and Georgia-Florida borders. It merges with the Flint River at Lake Seminole, an artificial lake created by Woodruff Dam. The Apalachicola River flows from Lake Seminole through Florida into the Gulf of Mexico.
The Chattahoochee is 436 miles (702 km) long. It is used for navigation, hydroelectric power, flood control, recreation, and municipal water supply. There are a number of lakes on the Chattahoochee, all of them created by dams. In addition to Lake Seminole, they include Walter F. George (Eufaula) and Sidney Lanier lakes.
