|Status||Repealed 30 March 2020|
Reason for Decision
Under the Temporary Water Restrictions (Lower Darling Regulated River Water Source) Order 2018 (as amended), all water take from the Lower Darling Regulated River Water Source has been restricted, unless use has been for town water supply, domestic use, stock watering, irrigation of existing permanent plantings (such as vineyards and orchards).
The restriction was put in place:
- “to cope with a water shortage” - remaining water supplies in the Lower Darling were at critically low levels and had to be protected for high priority needs and permanent plantings for as long as possible. Timing of the next inflow was unknown.
- in relation to “threat to public health and safety” - town water supply and domestic supplies are crucial for public health and safety and were under threat without intervention. These mitigation measures were needed to extend supplies until additional inflows arrive.
As a result of recent rainfall events across the northern NSW Murray Darling Basin and subsequent inflows, flow forecasts (as at 23 March) indicate that Lake Wetherell will receive 290 – 355 GL over the coming weeks, with flows arriving from 10 March. There is forecast to be enough water captured in the Menindee system to provide connectivity to the Murray and deliver high priority needs, including critical environmental needs, along the Lower Darling for at least 12-18 months.
The repeal of the restriction will allow full allocation to high priority needs including town water, stock and domestic, and high security. Current water frozen in general security accounts in the Lower Darling is 14.8 GL, and about 100 GL/year is needed to run the Lower Darling at seasonal minimums to maintain connectivity with the Murray River, therefore the extra water to deliver the account balance in 2019/20 would not unduly increase resource security risk. This means that the temporary water restriction applied in the public interest, is no longer required.
Reasons for decisions
Temporary water restriction – section 324
Due to periods of heavy rainfall in the northern basin since mid-January and substantial inflows, there is forecast to be adequate recovery in the Menindee Lakes system to support high priority needs through to at least the end of next summer, likely longer.
In these circumstances, water security has been restored, meaning the temporary water restriction applied in the public interest, is no longer required. It is therefore now in the public interest to repeal the temporary water restriction order.
