Jim Woodruff Dam is a hydroelectric dam on the Apalachicola River, about 1000 ft south of that river's origin at the confluence of the Flint and Chattahoochee Rivers. The dam impounds Lake Seminole on the common border of Florida and Georgia. The dam is named in honor of James W. Woodruff, Sr., a Georgia businessman who spearheaded the development of the Apalachicola-Chattahoochee-Flint Project. Electricity from the dam is marketed by the Southeastern Power Administration.
