A federal judge in D.C. has ruled in favor of Georgia, the Corps of Engineers, the Atlanta Regional Commission (ARC), and the Cobb County-Marietta Water Authority in a dispute over allocation of water from Lake Allatoona.

In Georgia’s other long-running water wars battle with the Florida, the U.S. Supreme Court also sided with Georgia, ruling in 2021 that Florida failed to prove its allegations that Georgia’s water consumption from the Chattahoochee and Flint river systems, which include Lake Lanier, caused the failure of Florida’s oyster industry in Apalachicola Bay.

Representatives of water supply systems in Gwinnett, Forsyth and Hall counties finalized an agreement with the Georgia the following year guaranteeing them water from Lake Lanier through 2050.
