Assessing the status of groundwater in the Great Artesian Basin How much time does water takes to reach to the ground? The Carmichael mines 12,000ML forecasted use (equivalent to 4% of the water extracted from the Great Artesian Basin in Queensland last year) would put it alongside the biggest annual users of Great Artesian Basin water, such as the Olympic Dam copper and uranium mine in South Australia, which currently draws 10,000ML each year. Uncontrolled water flow from bores and open earth bore drains reduces water pressure and volume. Gravity causes rain, melting snow and other water in the catchment to run downhill where it flows into creeks, rivers, lakes and eventually the ocean.
