Thanks to favourable conditions and the recent increasing volume of River Murray unregulated flows, large volumes of water are being released from the barrages into the Coorong.

“Last night, favourable wind conditions, tides and swells were identified for the coming week these conditions, paired with an increased volume of River Murray unregulated flows unveiled a perfect time to push water out of River Murray barrages into the Coorong.” Minister for Water and the River Murray Ian Hunter said.

“We have a rare opportunity to help make things right for a healthy, working Murray.”

Unregulated flows means that the River Murray flows has not been captured (regulated) in the Murray-Darling Basin Authority-controlled storages for irrigators.

Up to 80,000 megalitres a day of water will be released from the barrages to remove accumulated salt from Lake Albert, sand from the Murray Mouth and improve water quality in the Coorong.

“This is an unusual opportunity, considering that irrigation allocations were set at only 52 % for the 2016-17 water year, and increased to 89 % just last Friday.” Mr. Hunter said.

“Releasing large volumes of water in a controlled action such as this reduces the risk of lake shore erosion by lowering water levels.”

The event started yesterday and is being carried out until Wednesday 10 August 2016, weather conditions permitting.

All water users are advised that these flow conditions may present a hazard.

Background

Unregulated flows are an important source of water for environmental and operational activities in South Australia.

This is the first time since August 2014 that South Australia has received unregulated flows; this unregulated flow arises from the Murrumbidgee, Ovens, Kiewa and Goulburn Rivers, where rainfall and inflow has occurred downstream of the major storages.

This operation is being managed by the Department of Environment, Water and Natural Resources and SA Water (DEWNR). River Murray flows will continue to be closely monitored by DEWNR.
