Risk of spill update for Murray and Campaspe systems

The Resource Manager for northern Victoria today updated the risk of spill in the Murray and Campaspe systems.

The risk of spill in the Murray and Campaspe systems during 2017/18 remained above the 10 per cent threshold needed to declare a low risk of spill.

Resource Manager Dr Mark Bailey said the risk of spill from Lake Hume remained at 100 per cent.

“Victoria’s share of Lake Hume stayed full throughout September. This means that Victoria could not store additional water that flowed into its share of Lake Hume,” Dr Bailey said.

“There will be a deduction from spillable water accounts in the Murray system. The volume and percentage deducted will be confirmed in the seasonal determination announcement on October 16.

“The risk of spill from Lake Eppalock in the Campaspe system is about 22 per cent,” Dr Bailey said..

“No spills have occurred from Lake Eppalock so far this year.”

Dr Bailey said the risk of spill assessment did not describe the chances of flooding in the Murray or Campaspe systems this season.

“The risk of spill is a water accounting assessment,” he said.

“It does not refer to flood risks downstream of the storages.”
