The first indication of the existence of an underground fresh water area in the county of Robinson was noted by Dr R. Lockhard Jack, and referred to by him as the "Wurkagee-Witera Fresh Water Area" in Bulletin No. 1 of the Geological Survey of South Australia, in connection with the geology of portions of the Counties of Le Hunte, Robinson and Dufferin, with special reference to the underground water supplies. In this Bulletin only the extreme south eastern edge of a fresh water area is suggested namely that occurring in the Hundreds of Wurkagee and Witera. But the existence of fresh water at very shallow depths further westward towards the coast in the Hundreds of Campbell, Forrest and Ripton has been known to the residents in those districts for many years, and a considerable number of wells have been sunk in the area, and its water tapped for stock and domestic purposes. With a view to ascertaining the extent of this fresh water area in the Hundreds referred to, a preliminary investigation was commenced in the neighbourhood of the township of Flinders by Mr J. I. Miller who located a number of wells and collected certain information in connection with them. These data have been considerable supplemented by the present Engineer, Western Districts, and his Engineering Assistant. The whole of the data collected by these earlier investigators has been made available to this Department.
