Lake Yonah is a lake on the Tugaloo River, separating Georgia and South Carolina. The lake is created by the Yonah Dam, which is owned by Georgia Power. Lake Yonah is a residential lake with about seventy-two vacation and permanent homes. After the Tugaloo River flows from Yonah through the lower dam, it continues to Lake Hartwell, and joins the Savannah River, which empties into the Atlantic Ocean. Another tributary to this great river is the Seneca River, which flows into it from South Carolina. Lake Yonah is also a source of fresh water for the town of Toccoa, which is about twenty miles away.
