The Apalachicola watershed (HUC 03130011) covers approximately 19,000 square miles in the southeastern United States, including parts of Georgia, Alabama, and Florida. The hydrology of the region is heavily influenced by the Apalachicola River, which flows through the watershed and empties into the Gulf of Mexico. The region experiences a humid subtropical climate, with hot summers and mild winters. The watershed is also home to several reservoirs, including Lake Seminole and the Jim Woodruff Dam, which provide water for irrigation, hydroelectric power, and recreation. Snowfall is rare in the region, with only a few inches falling annually in the highest elevations. However, the watershed is prone to heavy rainfall events, which can lead to flooding and erosion. The Apalachicola River is known for its rich biodiversity, supporting numerous species of fish, birds, and other wildlife.
