Description

The Great Artesian Basin Coordinating Committee (GABCC) requested bore hole data from the state and territory government databases to be collated to estimate the number of bore holes that have been drilled into the Great Artesian Basin (GAB). This is to inform discussions on the legacy of the 140 years of past drilling activity with respect to the long term management of the groundwater resources of the GAB.

11 communities. That is one replacement bores may retire 2 or 3 existing bores. This has been the case for many of the GABSI bore capping projects. 4.4 Number of bores with uncontrolled artesian flow Changes to the artesian flow status of water bores are not always reported, but there is more consistent reporting associated with a state monitoring program or where bores have been part of GABSI programs. Similarly, changes to bores structural integrity and their capability to shut off or restrict artesian flows changes with time and are not necessarily reported to state government agencies and captured on the relevant databases. The number of bores under artesian conditions varies in response to changes to the groundwater pressure distribution across the GAB. To reliably report the condition of the bores at any particular time a comprehensive census would be required. The data reported in Table 6 is based on the best available information however in some cases this information may be more than 20 years old and consequently not considered up to date.
