I refer the minister to her answer to question without notice 1573 informing Parliament that the estimated annual ground water recharge is 2 300 gigalitres, of which 1 909 gigalitres represents the sustainable yield of fresh water that we can draw on. (1) Did the estimates given by the minister in her answer include the estimated 440 gigalitres annual recharge and the 300 gigalitre sustainable yield of the south Yarragadee aquifer? (2) If not, when will the Water and Rivers Commission update its estimates to include the south Yarragadee data? Hon TOM STEPHENS
AnswerView source ↗
The Minister for the Environment has provided the following reply - (1) No. Estimates of recharge to the Perth basin included estimates for the south west Yarragadee. However, recharge figures now being derived will provide a more accurate estimate of recharge in the south west region. The Water and Rivers Commission has not released an estimate of 300 gigalitres a year for sustainable yield. (2) The commission regularly updates its ground water resources information. Findings from south west Yarragadee investigations will be incorporated into state water resources figures upon completion of the Blackwood water management plan, which is scheduled for the last quarter of 2004.
