The Chattooga River (also spelled Chatooga, Chatuga, and Chautaga, variant name Guinekelokee River) is the main tributary of the Tugaloo River. Its headwaters are located southwest of Cashiers, North Carolina, and it stretches 57 miles (92 km) to where it has its confluence with the Tallulah River within Lake Tugalo, held back by the Tugalo Dam. The Chattooga and the Tallulah combine to make the Tugaloo River starting at the outlet of Lake Tugalo. The Chattooga begins in southern Jackson County, North Carolina, then flows southwestward between northwestern Oconee County, South Carolina, and eastern Rabun County, Georgia. The "Chattooga" spelling was approved by the US Board on Geographic Names in 1897.The Chattooga River flows into Tugalo Lake where it joins the Tallulah River. After flowing through Tugalo Dam the combined rivers become the Tugaloo River which, along with the Seneca River, becomes the Savannah River below Lake Hartwell. Downstream from that point, the water flows into the Atlantic Ocean near Savannah, Georgia. The Chattooga was used as a setting for the fictional Cahulawassee River in the book and film Deliverance.
