INTRODUCTION The objective of this work was to investigate the groundwater potential and subsequently construct a production bore providing a water supply for the community at Balingura outstation. The work was carried out in August 1988 by the Water Resources Group of the Power and Water Authority on behalf of the Aboriginal Essential Services of the Power and water Authority. Preliminary hydrogeological assessment, interpretation of aerial photographs hydrochemical study and other relevant studies of the area were carried out in the office. This was followed by a field reconnaissance in September 1986 during which three sites were selected and pegged in a close vicinity of the outstation Balingura is situated 15 km south-west of Galiwinku and 18 km south-east of Ramingining at AMG co-ordinates 501500 - 8619700. The area is covered by topographical map Howard 1: 100 000 Sheet 5973 and geological map Arnhem Bay/Gove N.T. 1:250 000 Sheet SD/53-3/4. It is accessible by a four wheel drive track via Miningadja and Naluyidi throughout the year. At present the population of the community is estimated to be at 15. The Arnhem Bay/Gove NT Map Sheet contains parts of three major physiographic units of Arnhem Land: the Coastal Plain, the Gulf Fall and the Arafura Fall. The outstation lies within the Arafura Fall Unit. The unit is controlled by the shallow-dipping rocks of the Wessel Group which are dissected by dendritic drainage. The maximum elevation in the area is about 50m above sea level. monsoonal climate with the wet to April. The mean annual the mean annual evaporation is Balingura lies in a season from December rainfall is 1400mm and approximately 2500mm. 2.HYDROGEOLOGY Geologically the area lies in the northern region of the Arafura Basin. It is underlain by the gently north dipping Raiwalla Shale of the Upper Proterozoic age. The Raiwalla Shale is composed of fissile grey, green and purple shale and flaggy fine grained sandstone. 96:HYGE01
