The Oostanaula River is a 49-mile-long river in northern Georgia, USA. The river has a long history of use by Native Americans and early settlers. It is a tributary of the Coosa River and begins in the Blue Ridge Mountains before flowing into the Coosa River at Rome, Georgia. The Oostanaula River is home to several hydroelectric power plants and has several reservoirs, including Carters Lake and Allatoona Lake. These reservoirs are used for recreation, such as boating and fishing, and also provide water for agricultural purposes. The river is also home to several rare species of fish, including the Cherokee darter and the Conasauga logperch. Despite its importance for recreational, agricultural, and ecological purposes, the Oostanaula River faces pollution, erosion, and habitat destruction.
