Macumba River (Arabana: Maka-Wimpa; Arrernte: Ura-Ingka), once known as Treuer River,[2] is an ephemeral freshwater stream in the far north of South Australia, that is part of the Lake Eyre Basin.
The river rises at the base of Macumba Hill and where the Alberga River joins with Hamilton and Currallulla creeks, it then flows in a south easterly direction entering the Kalamurina Sanctuary and eventually discharges into the Warburton River near the north eastern side of Lake Eyre. The Macumba is situated in an arid region, the Simpson Desert and flows only very rarely. Even in years that Lake Eyre fills, such as 2010, most of the water comes from the east, the Channel Country of Queensland.
The Finke River normally drains into the Simpson Desert to the north west of the Macumba, but in the first decade of the 20th century it is thought that the Finke flowed directly into the Macumba.[3] It is thought that the Finke has flowed to Lake Eyre via the Macumba in 1909, 1938, and 1945.[4]
The Macumba is part of the western rivers catchment of the Lake Eyre Drainange basin along with the Peake Creek and Neales River. The western rivers catchment is composed of sandplains, Acacia scrub, gibber plains and dissected residuals.[5]
Along with its tributaries the river has a catchment area of 39,000 square kilometres (15,058 sq mi).[4] The river passes through a number of permanent and semi-permanent waterholes including Ross waterhole, Walkinna waterhole, Tidnabucca waterhole, Ullabarracoola waterhole and Christmas waterhole. Eleven tributaries join the Macumba including the Alberga River, Stevenson Creek, Coomparana Creek, and Yardaparinna Creek.
