The Walloway Artesian Basin is approximately 160 miles north of Adelaide and is traversed by the main road from Adelaide to Maree via Orroroo and Hawker. The town of Orroroo lies on its western margin in the south-western corner of the Hundred of Walloway and the village of Johnburgh is situated in its northern part. The geophysical survey was carried out at the request of the Director of Mines for South Australia to assist his Department in the selection of sites for boring for artesian water and to delineate more precisely the limitations of the basin with regard to artesian flows. The gravity method was used as this method has proved successful elsewhere in determining the dimensions and form of sedimentary basins. This report gives an account of the survey and its results.
