The ACF River Basin is the drainage basin, or watershed, of the Apalachicola River, Chattahoochee River, and Flint River, in the Southeastern United States.

The Apalachicola River is a river, approximately 160 mi (180 km) long in the state of Florida. The river's large watershed, known as the ACF River Basin, drains an area of approximately 19,500 square miles (50,505 km2) into the Gulf of Mexico. The distance to its farthest head waters in northeast Georgia is approximately 500 miles (800 km). Its name comes from the Apalachicola people, who used to live along the river.

The Chattahoochee River forms the southern half of the Alabama and Georgia border, as well as a portion of the Florida - Georgia border. It is a tributary of the Apalachicola River, a relatively short river formed by the confluence of the Chattahoochee and Flint rivers and emptying from Florida into Apalachicola Bay in the Gulf of Mexico. The Chattahoochee River is about 430 miles (690 km) long. The Chattahoochee, Flint, and Apalachicola rivers together make up the Apalachicola–Chattahoochee–Flint River Basin. The Chattahoochee makes up the largest part of the ACF's drainage basin.

The Chipola River is a tributary of the Apalachicola River in western Florida. It is part of the ACF River Basin watershed.

The Flint River is a 344-mile-long (554 km) river in the U.S. state of Georgia. The river drains 8,460 square miles (21,900 km2) of western Georgia, flowing south from the upper Piedmont region south of Atlanta to the wetlands of the Gulf Coastal Plain in the southwestern corner of the state. Along with the Apalachicola and the Chattahoochee rivers, it forms part of the ACF basin. In its upper course through the red hills of the Piedmont, it is considered especially scenic, flowing unimpeded for over 200 miles (320 km). Historically, it was also called the Thronateeska River.

Johns Creek is an 8.0-mile-long (12.9 km) stream which begins in southern Forsyth County, Georgia and runs south-southwestward through the eastern part of northern Fulton County, Georgia. It is a tributary of the Chattahoochee River and has no official stream gauges.

Peachtree Creek is a major stream in Atlanta. It flows for 7.5 miles (12.1 km) almost due west into the Chattahoochee River just south of Vinings.

Sope Creek is an 11.6-mile-long (18.7 km) stream located in Cobb County, Georgia, United States. It is a significant tributary of the Chattahoochee River. It was known as Soap Creek during the 19th century. A section of Sope Creek runs through the Chattahoochee River National Recreation Area.

The Soque River and its watershed are located entirely within the county boundaries of Habersham County in northeast Georgia. The Soque is a tributary of the Chattahoochee River. Portions of the river run along State Route 197.

Sweetwater Creek is a 45.6-mile-long (73.4 km) stream in the U.S. state of Georgia, west of Atlanta. It begins in southwestern Paulding County, flowing generally eastward into southwestern Cobb County, then turning south into eastern Douglas County. It is a tributary of the Chattahoochee River, and near its end it is the centerpiece of Sweetwater Creek State Park.
Vickery Creek or Big Creek is a 26.5-mile-long (42.6 km) stream in Forsyth and Fulton counties in Georgia.

Its source is located just north of the intersection of Georgia State Route 9 and Georgia State Route 20, in Forsyth County, about 1 mile directly south of downtown Cumming.
Willeo Creek is a 6.7-mile-long (10.8 km) stream in the U.S. state of Georgia, and is located in the north-northwestern part of metro Atlanta. It is a significant tributary of the Chattahoochee River, into which it flows at Bull Sluice Lake, just upstream from Morgan Falls Dam and downstream from the Chattahoochee Nature Center. Together, the two streams form nearly all of the county line between Fulton to the east and Cobb to the west.
Nancy Creek is a 16.3-mile-long (26.2 km) stream in northern Atlanta, Georgia, United States. It begins in far northern DeKalb County, just north of Chamblee, and flows southwestward into Fulton County, through the far southeast corner of Sandy Springs, then through the Buckhead area of Atlanta. It empties into Peachtree Creek, which then flows into the Chattahoochee River, south of Vinings and Paces. The Chattahoochee eventually joins with the Flint River to create the Apalachicola River, which flows into the Gulf of Mexico. The North Fork Nancy Creek is a major tributary, while Little Nancy Creek tends to run low or dry. Other tributaries include Bubbling Creek which originates in Chamblee, Perimeter Creek which originates in Dunwoody and Silver Creek which includes the 38-acre Silver Lake and Little Silver Lake.

Apalachicola Bay is an estuary and lagoon located on the northwest coast of the U.S. state of Florida. The Apalachicola Bay system also includes St. George Sound, St. Vincent Sound and East Bay, covering an area of about 208 square miles (540 km2). Four islands, St. Vincent Island to the west, Cape St. George Island and St. George Island to the south, and Dog Island to the east, separate the system from the Gulf of Mexico. Water exchange occurs through Indian Pass, West Pass, East Pass and the Duer Channel. The lagoon has been designated as a National Estuarine Research Reserve and the Apalachicola River is the largest source of freshwater to the estuary. Combined with the Chattahoochee River, Flint River, and Ochlockonee River they drain a watershed of over 20,000 square miles (50,000 km2) at a rate of 19,599 cubic feet (550 m3) per second according to the United States Geological Survey in 2002.

Lake Lanier is a reservoir in the northern portion of the U.S. state of Georgia. It was created by the completion of Buford Dam on the Chattahoochee River in 1956, and is also fed by the waters of the Chestatee River. The lake encompasses 38,000 acres (150 km2) or 59 square miles (150 km2) of water, and 692 miles (1,114 km) of shoreline at normal level, a "full pool" of 1,071 feet (326 m) above mean sea level and the exact shoreline varies by resolution according to the coastline paradox. Named for American poet Sidney Lanier, it was built and is operated by the U.S. Army Corps of Engineers for flood control and water supplies. It is patrolled by the Georgia Department of Natural Resources (GDNR), as well as local law enforcement.

Lake Oliver is a 2,150-acre (8.7 km2) reservoir on the Chattahoochee River, which lies south of Goat Rock Dam. The lake is created by the Oliver Dam and Generating Plant, which was completed in 1959 by Georgia Power.

The Walter F. George Lake, named for Walter F. George (1878–1957), a United States Senator from Georgia, is formed on the Chattahoochee River along the state line between Alabama and Georgia. It is also widely known by the name, Lake Eufaula – particularly in Alabama, where the state legislature passed a resolution on June 25, 1963, to give the lake that name. The 46,000-acre lake extends north about 85 miles (140 km) from the Walter F. George Lock and Dam and has approximately 640 miles (1,030 km) of shoreline. Popular activities along the lake include camping and trophy fishing.

West Point Lake is a man-made reservoir located mostly in west-central Georgia on the Chattahoochee River and maintained by the U.S. Army Corps of Engineers (USACE). The Chattahoochee river flows in from the north, before flowing through the West Point Dam, which impounds the lake, and continuing to Columbus, Georgia. Of the four major USACE lakes in the ACF River Basin, West Point Lake is the smallest by area containing 25,864 acres (10,467 ha) of water, and has the second shortest shoreline at 604 mi (972 km). The purposes of the reservoir are to provide flood control, hydroelectric power, and water storage to aid the navigation of the lower Chattahoochee.

The tri-state water dispute is a 21st-century water-use conflict among the states of Georgia, Alabama, and Florida over flows in the Apalachicola-Chattahoochee-Flint River Basin and the Alabama-Coosa-Tallapoosa River Basin. The U.S. Army Corps of Engineers has regulated water flow for the entire Chattahoochee River, from Lake Lanier in Forsyth County, Georgia, to Alabama and Florida.
