The Great Artesian BasinIn New South Wales, the discovery of the Great Artesian Basin (Fig. 9) in the late 19th century led to the construction of many artesian bores and the provision of assured water supplies of acceptable salinity on several stock routes previously classed as unreliable. Several thousand bores have since been drilled and water is conveyed through earthen channels for thousands of kilometres.
The bore drain is a unique solution to the stock watering problem in that it distributes the water and simultaneously provides a continuous water trough (Fig. 10). Drain lengths of 160 km from a single bore are not uncommon.
Accelerated mining of artesian supplies and consequent reduction of pressure and lowering groundwater levels led to a realization that this source was not unlimited. Extensive investigations, aimed at establishing the extent of the Great Artesian Basin, its safe yield and the characteristics of its waters, were set in train by Nimmo and others and a reasonable understanding of this unique water resource was available by 1930. This work has recently been extended and enhanced by Habermehl and Siedel of the Bureau of Mineral Resources, using the most advanced technical processes. A digital computer simulation model has been developed for the Great Artesian Basin and this provides satisfactory data for assessment purposes, planning and management decisions for some of the major aquifers. Recommendations for future exploitation can be based on model predictions.
