Of 608 wells, over 500 were located (70-80% of water wells). The area is used for sheep. Potable water is hard to obtain and yields are low. Crystalline basement rock either crops out or occurs at shallow depth and this inhibits the availability of groundwater. The only significant aquifer is the Algebuckina Sandstone where water of around 1 000 mg/l TDS is obtained. Standing water levels average 25-30 metres below ground level. Recharge is low and irregular and depletion of the groundwater is occurring in many areas. Pollution is not obvious but unexplained nitrate values averaging over 70 mg/l are known.
