The Jim Woodruff Dam, located about 1,000 feet (300 m) south of the original confluence of the Chattahoochee River, Flint River and Spring Creek to form the Apalachicola River and with a spillway 2,224 feet (678 m) wide, is a hydroelectric and navigational dam named in honor of James W. Woodruff, Sr., a Georgia businessman who spearheaded the development of the Apalachicola-Chattahoochee-Flint Project.
The dam crosses the state line between Georgia and Florida, with the eastern end of the dam being located in Georgia.
The Jim Woodruff Dam has a single lock, 450 feet (140 m) in length and 82 feet (25 m) wide, that provides navigational access to the lake and the upstream rivers from the Apalachicola River and Gulf of Mexico. Lake Seminole extends upstream along the Chattahoochee River for 30 miles (48 km) and up the Flint River for 35 miles (56 km).
^For many years, The Canada Goose was protected throughout most of Florida, with one exception, it was legal to hunt the goose on Lake Seminole. However, increases in the feral population has led to the season being opened statewide.
