The Ocmulgee River Basin drains over 6180 square miles across the center of Georgia before joining with the Oconee to form the Altamaha. The Ocmulgee River itself flows for approximately 255 miles, and consists of three subbasins: the Upper Ocmulgee, the Lower Ocmulgee, and the Little Ocmulgee. Other major tributaries include the the Yellow, Alcovy, and South Rivers. The name Ocmulgee comes from the Hitchiti oki + molki meaning “bubbling water.” The basin lies on originally Muscogee (Creek) land, and archaeologists have found evidence of a long line of civilization in this area dating back to the original Ice Age migration of humans into North America. The basin boasts high biodiversity, several state parks, and a long, impressively complex history. Continue exploring the Ocmulgee below.


The Ocmulgee basin is home to several major rivers, and each has its own conservation organizations. Learn more about the various organizations below.
