The island is bounded by the Murray River and its anabranch, Ulupna Creek. The Darling Anabranch is a naturally ephemeral system. It is between the Murray River and the Gunbower Creek, an anabranch of the Murray. A bayou is often an anabranch. They were close neighbours of the Maraura, further down the Great Darling Anabranch. The Darling Anabranch River is the eastern boundary. The term anabranch has been used for segments of anastamosing rivers. The Darling Anabranch contains archaeological cultural material and evidence of Aboriginal occupation. An anabranch that gets cut off from the main channel becomes an oxbow lake. The lake is connected to a smaller lake, Lake Uzhin, by an anabranch. In North America an anabranch is called a "braided stream". The Connors River is a river and anabranch located in Central Queensland, Australia.
