The Altamaha River is the largest river in southeast Georgia, flowing from the confluence of the Oconee and the Ocmulgee for about 137 miles before draining into the ocean near Brunswick, GA. Although the full Altamaha Basin encompasses the Ocmulgee and the Oconee Basins, the lower Altamaha and its tributary, the Ohoopee, are largely undeveloped and among the most intact rivers in Georgia. The name Altamaha comes from one of the three Indigenous chiefdoms of the Oconee River Valley area, and the basin lies on Muscogee (Creek) land. Continue exploring the Altamaha below.
