These borefields have been gradually increasing the quantity of water extracted from 1.3 to 15 million litres per day since 1982.
Arrows represent water flow paths.
A Borefield A consists of a total of 9 production bores in three main locations, and a total of 19 observation bores. Between 1982 and 1987 six of these production bores were flowing under artesian pressure. In 1987 pumps were installed to make up for the loss of artesian pressure, due to drawdown in the GAB aquifer. The final 3 production bores were constructed in 1991 on the southern shores of Lake Eyre South, within the boundaries of Lake Eyre National Park. Borefield A is located directly within the Lake Eyre and Hermit Hill Mound Spring complexes.
