The Ochlockonee and St. Marks watersheds cover approximately 3,600 square miles of south Georgia and north Florida. The Ochlockonee River originates in Georgia, receiving flow from numerous tributaries before it reaches Ochlockonee Bay on the Gulf of Mexico. About 1,080 miles of the watershed's 2,416 square miles lies within Florida.

The St. Marks watershed drains 1,204 square miles in Florida into Apalachee Bay, on the Gulf of Mexico. The biggest tributary to the St. Marks River, the Wakulla River, is fed by water from Wakulla Springs, one of the largest and deepest freshwater springs in the world.

Both watersheds are located in one of the more pristine areas of Florida, with a much lower population density and fewer stresses on the environment than in other parts of the state.
