USA - November 21st, 2011

Sediments flow out of Apalachicola Bay, an estuary and lagoon located on Florida’s northwest coast. The lagoon has been designated as a National Estuarine Research Reserve and the Apalachicola River is the largest source of freshwater to the estuary. Combined with the Chattahoochee River, Flint River, and Ochlockonee River they drain a watershed of over 20000 sqmi at a rate of 19599 cubic feet per second.

The Apalachicola Bay system also includes St. Georges Sound, St. Vincent Sound and East Bay, covering an area of about 208 sqmi. Four islands: St. Vincent Island to the west, Cape St. George Island and St. George Island to the south, and Dog Island to the east, separate the system from the Gulf of Mexico. Water exchange occurs through Indian Pass, West Pass, East Pass and the Duer Channel.

The coast of Florida’s pan-handle along the Gulf of Mexico is marked by a string of sandy beaches. To the East, green and tan sediments are present in the water, particularly in St. George’s sound, a waterway between the mainland and a long thin island chain in the lower right quadrant.

Further east, the waters appear dark brown due to sediments being discharged from the Ochlockonee River, a fast running river originating in Georgia, and terminating in Florida.

The Ochlockonee originates in southwest Georgia. As it flows through Ochlockonee River State Park, it is tidally influenced and a mixture of fresh, brackish, and salt water on the way to its terminus in Ochlockonee Bay. From there, it then empties into Apalachee Bay.

Further inland, in the center of the image, Lake Seminole can be seen. It is a man-made lake located in the southwest corner of Georgia along its border with Florida. 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 37500 acres of water. It is home to many species of fish, as well as alligators, snakes and various waterfowl.
