Tugaloo River

The Tugaloo River (originally Tugalo River) is a short river bordering the U.S. states of Georgia and South Carolina. It is fed by the Tallulah River and the Chattooga River, which each form an arm of Tugaloo Lake, on the edge of Georgia's Tallulah Gorge State Park. The Tugaloo then flows out of the lake via Tugaloo Dam, passing into Lake Yonah and out of Yonah Dam.

The river then ends as an arm of Lake Hartwell, as does South Carolina's Seneca River. After flowing out of Hartwell Dam, it is called the Savannah River.

Territorial claims to the river and its islands were settled with the Treaty of Beaufort in 1787, as interpreted in the two Georgia v. South Carolina cases before the U.S. Supreme Court in 1922 and 1989.

The name of the river comes from Tugaloo, a Cherokee town that was located on the river near the mouth of Toccoa Creek.
