The Chattahoochee River forms the southern half of the Alabama and Georgia border, as well as a portion of the Florida and 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 makes up the largest part of the ACF's drainage basin.
Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located 40 miles (64 km) east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Lock and Dam is named for Army Capt. Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.

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 sq mi (150 km2) of water, and 692 mi (1,114 km) of shoreline at normal level, a "full pool" of 1,071 ft (326 m) above mean sea level and the exact shoreline varies by resolution according to the coastline paradox. Named for poet Sidney Lanier, it was built and is operated by the U.S. Army Corps of Engineers for flood control and water supplies. Its construction destroyed more than 50,000 acres (20,000 ha) of farmland and displaced more than 250 families, 15 businesses, and relocated 20 cemeteries along with their corpses in the process.
Lake Lanier Islands is a resort complex built on a small group of islands on Lake Lanier, the largest lake in Georgia, located 60 miles northeast of Atlanta, Georgia.

The national recreation area, a National Park Service unit, was established on August 15, 1978, by President Jimmy Carter.
Hartwell Dam is a concrete and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Lake Hartwell. The dam was built by the U.S. Army Corps of Engineers between 1955 and 1962 for the purposes of flood control, hydropower and navigation. The concrete and earthen structure spans 15,840 feet (4,828 m). The concrete section is 1,900 feet (579 m) long and rises 204 feet (62 m) above the riverbed at its apex. The Hartwell Dam currently produces 468 million KWh of electricity annually, has prevented over $40 million in flood damage since completion and also provides recreation, water quality, water supply, along with fish and wildlife management.
The Kajaki Dam is one of the two major hydroelectric power dams of Helmand province in southern Afghanistan. The dam is located on the Helmand River 100 miles (161 km) north-west of Kandahar and is operated by the Helmand and Arghandab Valley Authority. It has a dual function, to provide electricity and to irrigate some 650,000 acres (1800 km2) of an otherwise arid land. Water discharging from the dam traverses some 300 miles (500 km) of downstream irrigation canals feeding farmland. As of July 2022 it produces up to 151 megawatts (MW) of electricity.
Lake Seminole is a reservoir located in the southwest corner of Georgia along its border with Florida, maintained by the U.S. Army Corps of Engineers. The Chattahoochee and Flint rivers join in the lake, before flowing from the Jim Woodruff Lock and Dam, which impounds the lake, as the Apalachicola River. The lake contains 37,500 acres (152 km2) of water, and has a shoreline of 376 mi (605 km). The fish in Lake Seminole include largemouth bass, crappie, chain pickerel, catfish, striped bass and other species. American alligators, snakes and various waterfowl are also present in the lake, which is known for its goose hunting.
Cougar Dam is a 519-foot (158 m) tall rockfill hydroelectric dam in the U.S. state of Oregon. It has a gated concrete spillway and a powerhouse with two turbines totaling 25 megawatts of electric power.
The September 2009 Southeastern United States floods were a group of floods that affected several counties throughout northern Georgia, Tennessee, Alabama, Mississippi, and Arkansas. The worst flooding occurred across the Atlanta metropolitan area. Continuous rain, spawned by moisture pulled from the Gulf of Mexico, fell faster than the local watersheds could drain the runoff.
J. Strom Thurmond Dam, also known in Georgia as Clarks Hill Dam, is a concrete-gravity and embankment dam located 22 miles (35 km) north of Augusta, Georgia on the Savannah River at the border of South Carolina and Georgia, creating Lake Strom Thurmond. U.S. Route 221 cross it. The dam was built by the U.S. Army Corps of Engineers between 1946 and 1954 for the purposes of flood control, hydroelectricity and downstream navigation. The concrete structure of the dam spans 1,096 feet (334 m) and rises 204 feet (62 m) above the riverbed, housing a power plant with an installed 380 MW capacity. The Dam has prevented over $3.1 million in estimated flood damage annually and also provides recreation, water quality, water supply, along with fish and wildlife management.
Richard B. Russell Dam is a concrete-gravity and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Richard B. Russell Lake. The dam was built by the U.S. Army Corps of Engineers between 1974 and 1985 for the purposes of flood control, hydroelectricity, recreation, additional stream flow regulation, water supply, and fish and wildlife management. The concrete structure of the dam spans 1,904 feet (580 m) and rises 210 feet (64 m) above the riverbed, housing a hydro-power plant with an installed 600 megawatts (800,000 hp) capacity.

Strom Thurmond Dam (1954).
The tri-state water dispute is a 21st-century water-use conflict among the U.S. 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.
Florida v. Georgia, 585 U.S. ___ (2018), was a decision by the Supreme Court of the United States in an original jurisdiction case. It involves a long-running dispute over waters within the ACF River Basin, running from the north Georgia mountains through metro Atlanta to the Florida panhandle, which is managed by the United States Army Corps of Engineers. Waters in the area have been stressed by the population growth of Atlanta over previous decades. The immediate case stemmed from droughts in 2011 and 2012 that caused economic damage to Florida due to lower water flows from the ACF River Basin into the panhandle, impacting its seafood production; Florida sought relief to have more water allocated towards them from the ACF by placing a water allocation cap on Georgia. The Supreme Court assigned a special master to review Florida's complaint, but ultimately found in 2016 that Florida had not fully demonstrated the need for more allocation. Florida challenged this determination to the Supreme Court. On June 27, 2018, the Supreme Court ruled 5–4 that the special master had not properly considered Florida's argument and remanded the case to be reheard and reviewed.
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.
