Quick Facts about the River

·         The 130-mile St. Marys River is a blackwater river located in southeast Georgia and is bordered by the Satilla River Basin to the north and the Suwannee River Basin to the west.

·         The headwaters are located in Okefenokee Swamp and Charlton County, and the river flows south before turning north and east, emptying into Cumberland Sound and the Atlantic Ocean between St. Marys, Georgia and Fernandina Beach, Florida.

·         The St. Marys River serves as the border between Georgia and Florida. The Georgia portion of the basin drains approximately 765 square miles (of 1,300 total square miles).

·         The 1988-90 land cover interpretation showed 41 percent of the basin in wetlands.

·         The population is centered mostly in Kingsland and Folkston.

·         The basin’s longleaf pine forests supplied naval stores—masts, turpentine and other forestry products—to the shipping and other industries until the early 1900’s when the last lumber mills closed due to the inability to effectively access profitable timber stands.

Biological Resources

o    Fifteen of the 34 species in the sunfish family Centrarchidae are present in the St. Marys River, making this family the largest group of fish species found in the river basin.

·         The fish populations in the St. Marys Basin are limited in productivity by acidic waters, low alkalinity, and extreme variation in flow.

·         The blackbanded sunfish and the banded topminnow are two fish species found in the basin that are currently listed by the state as rare species.

·         Wildlife in the basin includes deer, otter, beaver, raccoon, alligator, gopher tortoise, turkey and ribbon snakes. The middle portion of the river supports bear, panther, bobcat and the red-cockaded woodpecker.
