Jim Woodruff Dam

From Atlanta Water Shortage Wiki

Jim Woodruff Dam is the point where the Flint River and the Chattahoochee River come together to form Lake Seminole. The dam spans the Florida–Georgia border, and also the border between Jackson and Gadsden Counties in Florida. The dam is located near Chattahoochee, Florida. The Apalachicola River flows out of the dam. This earth dam is over a mile long with a central concrete and steel lock and water control structure.

The water released from Buford Dam at Lake Lanier needs to be enough to maintain a minimum flow rate of 4,750 cfs at the dam, in part to save the endangered mussels.
