 | | The water in the Great Artesian Basin (GAB) was first tapped in the late 1870's when the first bores or wells were sunk. |
 | | Today, the GAB is in equilibrium between recharge and discharge; that is, no further decrease in spring flow is expected providing no new developments occur. |
 | | Presently, the mine with draws 15 megalitres (4,000,000 gal) per day, however, it is planned to expand this to 33 megalitres (8,700,000 gal) per day (Harris 1992). |
