The Simpson Desert is a desert located in central Australia. Beneath it lies the Great Artesian Basin, waters from which rise to the surface both at several natural springs (especially at Dalhousie) and artificial bores (some drilled for stock routes, others during failed oil exploration.) The flow of water to the springs has been substantially reduced in recent years by over-exploitation and may soon cease.
