Altamaha River - Course

Course

The Altamaha River originates at the confluence of the Oconee River and Ocmulgee River, near Lumber City. At its source, the Altamaha River forms the border between Jeff Davis County to the south and Montgomery County to the north.

Bullard Creek Wildlife Management Area occupies the southern floodplain of the river's first few miles, after which the river marks the boundary between Toombs County to the north and Appling County to the south.

On the north side, Toombs County gives way to Tattnall County, in which the Ohoopee River joins the Altamaha. The Big Hammock Wildlife Management Area and Big Hammock Natural Area are located along the Altamaha at the Ohoopee confluence. Big Hammock Natural Area is a National Natural Landmark site, noted for its ecological biodiversity and many rare plant species, including Georgia plume.

Below Big Hammock, the tributary Beards Creek joins the Altamaha River from the north, after which the river marks the border between Long County to the north and Wayne County to the south. The Altamaha passes through Griffin Ridge Wildlife Management Area before flowing by Doctortown, near Jesup. A wide and swampy floodplain surrounds the river in this area.

Several miles below Doctortown Long County gives way to McIntosh County on the north side of the river. From this point to the river's mouth there are numerous wildlife management areas. The Sansaville Wildlife Management Area lies on the south side of the river, while the Altamaha Wildlife Management Area lies on the north and extends down to the river's mouth at Altmaha Sound. Wolf Island National Wildlife Refuge occupies Wolf Island on the Atlantic coast, north of Altamaha Sound. In its last several miles, the Altamaha River marks the boundary between McIntosh County on the north and Glynn County on the south. It is large.

The town of Darien lies just north of the Altamaha River's mouth. Several miles to the south lies the larger city of Brunswick. St. Simons Island lies on the south side of the Altamaha estuary. The estuary of the Altamaha River, where fresh and salt water mix, is about 26 square miles (67 km2) in size, one of the largest intact, relatively non-degraded estuary on the Atlantic coast. The Altamaha River Delta has been designated as a site of regional importance to shorebirds by the Western Hemisphere Shorebird Reserve Network (WHSRN).
