Atlanta, South Georgia, Alabama, and Florida are all in a political war for the waters of the Chatahoochee River and the water reserve held by Lake Lanier. An overlooked potential victim of this battle are the farmers of South Georgia. If Atlanta builds a pipeline to procure water from their rivers, they might not be able grow their crops.
Georgia has to have a larger supply of reserved water for times of low rainfall or drought. The only way to accomplish this is to build more dams with reservoirs. We could build them on the main large rivers, but it would be better to build them on tributaries that flow into large rivers for three main reasons. They would be cheaper, they would take up less land, and, if one of them happens to break, it won't flood half the state.
