The Chauga Mound (38OC1) is an archaeological site once located on the northern bank of the Tugaloo River, about 1,200 feet (370 m) north of the mouth of the Chauga River in present-day Oconee County, South Carolina. The earthen platform mound and former village site were inundated by creation of Lake Hartwell after construction of the Hartwell Dam on the Savannah River, which was completed in 1962.
