Following a request made by the Engineering and Water Supply Department to this Department for further investigations into the groundwater prospects in the Coober Pedy Area, a follow up survey to that of Mr. E.S. O'Driscoll and Mr. C. Bleys in 1959 was carried out by the author from 27 September 1962 to 3 October 1962. This survey has been incorporated in a regional hydrological survey of the Great Australian Artesian Basin and its fringe areas in South Australia, which has been continuing since May 1961. As a result of the drough stricken condition of the country in this area, and with the increasing population due to the current high demand for opal, the water problem has once again become acute. As the town water supply 500,000 gallon rainwater tank is now dry, water is being carted from Mount Willoughby Station some hundred miles to the north, at considerable cost to consumers and general inconvenience. It is understood this water is being partially supplemented in some instances by freshwater from Mr. F.H.C. Kunoth's private "Willow" bore some ten miles northwest of the township. As far as is known these are the only current sources of water for Coober Pedy at present being used. Apart from the drilling of a bore one and a half miles north of the township, none of the other recommendations made by O'Driscoll and Bleys in 1959 have been acted upon.
