Rising as the Barcoo on the northern slopes of the Warrego Range in Queensland, it is joined by the Alice River, turns southwest, and receives its principal tributary, the Thomson, from which point it is known as Cooper Creek. Crossing the South Australia border, it carries water to Lake Eyre. Its total length is 880 mi (1,420 km).
