Atlanta Journal Constitution:

Florida, Georgia (the Atlanta metro area) and Alabama are fighting it out for rights to the Chattahoochee River's Lake Lanier reservoir.

Georgia wants the US Army Corps of Engineers to guarantee enough water in the reservoir to supply the Metro Atlanta area for the next 20 years). The case, which will be heard by the Supreme Court of the United States will examine a settlement agreement signed in 2003 between Georgia, local leaders, federal officials and federal hydropower customers that would reserve up to 50% more water in Lanier for Atlanta's supply.

Meanwhile, Florida and Alabama are suing Georgia in a Federal District Court in Florida over whether Atlanta even has the right to extract water from the Lanier reservoir. Florida and Alabama argue that the federal project to dam the Chattachoochee and create Lake Lanier was primarily to control flooding and generate hydroelectric power and not to supply Atlanta with water.
