Risk of Spill on the Murray and Campaspe systems


Friday 10 November, 2017

Low risk of spill declared in the Murray system

The Resource Manager for northern Victoria today declared a low risk of spill in the Murray system.

Resource Manager for northern Victoria Mark Bailey said the risk of spill in the Murray system during 2017/18 was now below the 10 per cent threshold needed for a declaration to be made.

“Based on Victoria’s share of the volume held in Lake Hume, the risk of spill is about 3 per cent,” Dr Bailey said.

“The declaration follows relatively low inflows during October. Lake Hume is now slowly falling as releases for downstream irrigation and environmental demands occur.

“No spills occurred from the Victorian share of Lake Hume during October.

“All water remaining in spillable water accounts in the Murray system will be made available to entitlement holders for use or trade.”

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

“The risk of spill from Lake Eppalock in the Campaspe system is about 17 per cent,” said Dr Bailey. “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 this season.

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

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