This report covers an intensive survey of the groundwater resources of the southeastern portion of the State and is an important contribution to the study of the hydrology of Australian groundwaters. The State possesses a major economic asset, in a large part of the area described in this report, in that underground water supplies are available for stock, domestic requirements, and for irrigation purposes. There is no doubt that more and more use will be made of this resource as development proceeds. This report will provide a (basis upon which an assessment of the potential of any particular area can be readily made and it is expected that it will prove of great value to agriculturalists and pastoralists.
