Apalachicola River

The Apalachicola River is a major river in the Florida Panhandle, approximately 160 miles (260 km) long. It is formed by the confluence of the Chattahoochee and Flint Rivers at the Florida-Georgia border near Lake Seminole and flows southward through a vast floodplain before emptying into Apalachicola Bay and the Gulf of America. As part of the Apalachicola-Chattahoochee-Flint (ACF) River Basin, which drains about 19,500 square miles across three states, it stands as one of the largest and most ecologically significant river systems in the southeastern United States. The river and its floodplain support extraordinary biodiversity, including the highest diversity of amphibians and reptiles in North America north of Mexico, over 130 species of fish, numerous rare plants, and important habitats for migratory birds and mammals such as black bears and manatees. It is recognized as a biodiversity hotspot and International Biosphere Reserve. The Apalachicola River provides essential freshwater, nutrients, and detritus to the highly productive Apalachicola Bay estuary, sustaining one of the most valuable oyster fisheries and commercial seafood industries in the region. Its relatively natural character makes it a critical natural laboratory and a vital ecological corridor in an increasingly developed landscape.
