ARC statement on the Landmark Apalachicola-Chattahoochee-Flint Agreement
This is a win-win solution that establishes a clear path to resolve the decades-long dispute over our shared water resources. We appreciate the leadership of Governor Kemp and Governor Ivey and the willingness of all parties to find common ground.
As leaders in water stewardship, we are gratified the parties have come together on an agreement that both protects metro Atlanta’s water supply and provides the downstream flows Alabama requested. We look forward to participating in the Corps’ public comment and environmental review process and are eager to find new opportunities to collaborate outside of the courtroom.

The Corps must develop a “water control plan” for each of its reservoirs that explains how it will be operated to meet its various authorized purposes, such as water supply, flood control, and hydropower generation. Where there are multiple reservoirs in a system, as there are in the ACF and ACT Basins, the Corps must prepare a Master Water Control Manual that includes the individual water control plans for each reservoir and that describes how the system will be operated.
The master water control manual for the ACF Basin reservoirs was stalled for decades due to a combination of litigation, the ongoing interstate negotiations, and political maneuvering in Congress.
This changed in 2011, when the 11th Circuit issued a key ruling recognizing that the Corps was authorized to use Lake Lanier to provide a safe and reliable water supply for Metro Atlanta. That decision also recognized, however, that the Corps needed to make a final decision about how Lake Lanier would be operated for water supply. To ensure that happened, the court gave the Corps one year to determine how much water it believed could be supplied.
This direction set the stage for developing a new Master Water Control Manual for the ACF reservoirs, including Lake Lanier. Based on analyses prepared in response to the 11th Circuit’s order, the Corps found it has the authority to meet all of metro Atlanta’s long-term projected water supply needs. The Corps stated that it could not make a final decision about whether it would do so, however, until all required environmental studies were completed.
Over the next five years, from 2012 to 2017, the Corps prepared draft and final versions of an updated Master Water Control Manual for the ACF Basin. This included a decision about how much water it will provide to Metro Atlanta from Lake Lanier and the Chattahoochee River downstream of the reservoir. As is also required, the Corps prepared an Environmental Impact Statement (EIS) under the National Environmental Policy Act (NEPA), analyzing the environmental benefits and impacts that would result from its updated operating plan. Draft and final versions of the Water Control Manual and EIS, as well as comments submitted on the draft, are available here.
The Corps signed a Record of Decision (ROD) adopting the Final ACF Water Control Manual on March 30, 2017. The ROD states that the Corps will reallocate storage in Lake Lanier and release water into the Chattahoochee River to accommodate Metro Atlanta’s long-term (year 2050) projected water supply needs. Among other things, the Corps’ decision was based on its finding that meeting Metro Atlanta’s needs and adjusting its reservoir operations “would have no more than negligible effects overall on flow conditions in the Apalachicola River, or water quality, salinity, and fish and aquatic resources in the River or Bay.”
On April 5, 2017, Alabama sued to challenge the Updated Manual and Final Environmental Impact Statement. On April 27, 2017, three environmental groups (including the Apalachicola Riverkeeper) filed a related challenge the Corps’ Updated Manual.
In August 2021, the U.S. District Court for the Northern District of Georgia ruled for the Corps, affirming its decision to meet Metro Atlanta’s water supply needs and rejecting all remaining claims by Alabama and the environmental groups. Summarizing, the court explained:
The ACF Basin Master Water Control Manual Update assures a dependable supply of water from Lake Lanier and the Chattahoochee River to the Atlanta Metropolitan region through the year 2050. It does so without significant sacrifices to environmental standards, and recognizes the need to maintain other uses of the ACF system such as flood control, hydropower generation, fish and wildlife conservation, navigation and recreation. The effect upon the Apalachicola River and Bay will be negligible. The decision was not arbitrary or capricious. The Plaintiffs have not met their burden of showing that this delicate balance should be upset. In the absence of an agreement among Georgia, Florida and Alabama, there is no better alternative. Decades of deferral and delay due to litigation should end.
Alabama and the environmental groups have appealed the court’s decision to the U.S. Court of Appeals for the Eleventh Circuit. This appeal is currently pending.
On January 20, 2021, the Corps executed a long-term water supply storage contract with the State of Georgia for Lake Lanier. This contract provides for permanent storage in Lake Lanier sufficient to meet the future water supply needs of metropolitan Atlanta communities that withdraw from the lake (Gwinnett County, the City of Buford, the City of Gainesville, the City of Cumming, and Forsyth County) and upstream communities. The 2011 11th Circuit ruling and the updated ACF Water Control Manual already ensure that sufficient water will be available in the river below Lake Lanier to meet the long-term needs of the other metropolitan Atlanta communities.
