The Chattahoochee River is 430 miles long and runs from its headwaters in the Blue Ridge Mountains of Georgia to its confluence with the Flint River in Florida where it becomes the Apalachicola River. It has played a significant role in the history of the area, serving as a major transportation route during the Civil War and as a source of water for agriculture and industry. The river is also a popular destination for recreational activities such as fishing, kayaking, and hiking. Several dams and reservoirs have been built along the river, including the Buford Dam which created Lake Lanier, a popular recreational spot for boating and fishing. The river's hydrology has been impacted by urbanization and agriculture, leading to water quality concerns and disputes over water usage.
