2023/24 Risk of Spill update for Murray, Goulburn and Campaspe systems

The Resource Manager for northern Victoria today updated the 2023/24 risk of spill information for each of the Murray, Goulburn and Campaspe systems.

Resource Manager Mark Bailey said while recent conditions have been drier, the risk of spill remained above the threshold for a declaration.

“Releases to manage the rate of fill at Lake Hume continued through August,” Dr Bailey said. “The volumes deducted from Murray system spillable water accounts will be confirmed in the September 15 seasonal determination announcement. 

“Releases from Lake Eildon and Lake Eppalock are now meeting downstream operating needs. However, it is still possible for releases to manage the rate of fill to occur.

“The risk of spill and potential for further deductions from spillable water accounts in the Goulburn system is about 75 per cent and about 70 per cent in the Campaspe system."

Dr Bailey added the risk of spill assessment referred to water accounting only and did not describe the chances of flooding this season.

Trading Opportunities

Allocation trade from New South Wales to Victoria is limited to the lesser of a net annual volume of 200 GL or a volume that keeps the risk of spill in the Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent. As Victoria’s share of Hume and Dartmouth is close to full, trade from New South Wales to Victoria is not possible. The volume available for trade is updated with each risk of spill announcement. 

Next announcement on risk of spill

The risk of spill in the Murray, Goulburn and Campaspe systems in 2023/24 will be updated on Tuesday 10 October 2023.
