An 18-year water war between Georgia, Alabama, and Florida has come to an end of sorts: A federal appellate court has voided an Army Corps of Engineers agreement that would have given Georgia the rights to nearly 25 percent of federal reservoir Lake Lanier as a source of drinking water for metro Atlanta. Alabama and Florida had sued over the plan, saying it would siphon off water that would otherwise flow to their states. Atlanta, which has been accused of not being mindful of water resources while encouraging rampant growth, is “the big loser here,” says water-law expert George William Sherk. The three states are negotiating a new division of water, as a record drought continues.
