Modern drilling techniques mean that groundwater development is currently concentrated in the deeper, and generally more reliable, aquifers of the Volcanics. Therefore alluvial bores or wells would usually only be attempted where the Volcanics or Jasper Gorge Sandstone are not present, or surface water options are not economical. Alluvial wells have supplied good quality water on Waterloo Station, and despite the potential for pollution due to their shallow nature, all samples have been chemically suitable for stock and human consumption. These waters are characterised by TDS and moderately high silica values which are very similar to the water quality of the basalts on which they lie. 3.2.5 Kinevans Sandstone The Kinevans Sandstone immediately underlies the Antrim Plateau Volcanics in the escarpments around the junction of Cattle Creek and the West Baines River, with rare outcrops on top of the Angalarri Siltstone in the Horse Creek Area. It may be present further west under the basalt but this has not been proven. The Kinevans Sandstone is a thin sheet of red brown silty quartz sandstone which is between 1 and 15 m thick. On Amanbidji seepage water supplies only were encountered in the Kinevans Sandstone. Despite some faulting the friable poorly sorted nature of the unit means that aquifer potential has not been improved by fracturing and it is not recommended as a water supply target. 4. SURFACE WATER 4.1 Surface Water Occurrence Surface water flow is confined to the wet season, except for those creeks receiving groundwater input from springs. During the average Wet, flow of the West Baines and Negri Rivers, and their tributaries, is often accompanied by sheet flow over much of the flood plain areas. After the Wet all drainages deplete to form unconnected waterholes (Plate 4), the majority of which are dry by about October. There are currently no manmade surface water storages on Waterloo Station, but cattle water at natural waterholes throughout the station until these become dry. The good groundwater potential precludes surface water development, except in areas such as the lower floodplains of the West Baines River, which are underlain by siltstone with very limited aquifer potential. In these areas springs should be used where present, or if not, excavated tanks situated away from the main flow channels and harvesting sheet flow runoff show potential. Surface water studies have been directed at designing a structure suitable for the floodplain areas (Zones 1 and 2 on the water resources development map) to conserve enough of the
