The Apalachicola River is a river, approximately 160 miles (260 km) long, in the state of Florida. The river's large watershed, known as the Apalachicola, Chattahoochee and Flint (ACF) River Basin, drains an area of approximately 19,500 square miles (50,500 km2) into the Gulf of Mexico. The distance to its farthest head waters in northeast Georgia is approximately 500 miles (800 km). Its name comes from Apalachicola Province, an association of Native American towns located on what is now the Chattahoochee River. The Spanish included what is now called the Chattahoochee River as part of one river, calling all of it from its origins in the southern Appalachian foothills down to the Gulf of Mexico the Apalachicola.

Lake Seminole is a reservoir located in the southwest corner of Georgia along its border with Florida, maintained by the U.S. Army Corps of Engineers. The Chattahoochee and Flint rivers join in the lake, before flowing from the Jim Woodruff Lock and Dam, which impounds the lake, as the Apalachicola River. The lake contains 37,500 acres (152 km2) of water, and has a shoreline of 376 mi (605 km). The fish in Lake Seminole include largemouth bass, crappie, chain pickerel, catfish, striped bass and other species. American alligators, snakes and various waterfowl are also present in the lake, which is known for its goose hunting.
