Coosa River, Near Pell City, Alabama
The Coosa River is a tributary of the Alabama River in the U.S. states of Alabama and Georgia. The river is about 280 miles (450 km) long altogether.
The Coosa River is one of Alabama's most developed rivers. It begins at the confluence of the Oostanaula and Etowah rivers in Rome, Georgia, and ends just northeast of the Alabama state capital, Montgomery, where it joins the Tallapoosa River to form the Alabama River just south of Wetumpka. Around 90% of the Coosa River's length is located in Alabama. Coosa County, Alabama, is located on the Coosa River.
Most of the river has been impounded, with Alabama Power, a unit of the Southern Company, maintaining seven power dams on the Coosa River. The hydroelectric power dams have provided power to the citizens of Alabama, but are costly to some species endemic to the Coosa River.
