SOUTH WEST WATER PLAN
I refer to the south west water plan. (1) Within the south west water plan, what are the allocation limits for the Sue Coal Measures, Cattamarra Coal Measures and Lesueuer Sandstone for 2010–11? (2) What modelling has been conducted using the south west aquifer modelling system for these aquifers? (3) How does this water infiltrate through these and other aquifers of the south west? Hon HELEN MORTON

The minister has provided the following advice — (1) The current 2010–11 allocation limits are: Sue Coal Measures, 3 500 000 kilolitres per year; Cattamarra Coal Measures, 10 000 000 kilolitres per year; and Lesueuer Sandstone, 4 510 000 kilolitres per year. (2) Version two of the south west aquifer model was used to model different extraction and climate scenarios in the south west ground water allocation plan area. This is documented in the “South West Basin Groundwater Resource Assessment: Application of SWAMS and ESCP Models”, Department of Water, 2009. (3) Generally, water infiltrates through the Leederville aquifer to the Sue Coal Measures, Cattamarra Coal Measures, the Lesueuer Sandstone and other aquifers in the plan area.
