Risk of Spill update for Murray and Campaspe systems

The Resource Manager for northern Victoria today updated the 2025/26 risk of spill information for the Murray and Campaspe systems.

Resource Manager Mark Bailey said the risk of spill in the Murray and Campaspe systems had fallen but remained above the 10 per cent threshold needed to make a low risk of spill declaration.

“With below average inflows in Lake Hume and Lake Eppalock during August, the risk of spill has reduced in both the Murray and Campaspe systems,” Dr Bailey said.

“The risk of spill at Lake Hume in the Murray system is now about 25 per cent. The risk of spill from Lake Eppalock in the Campaspe system has decreased to 17 per cent.”

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

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 Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent. The current risk of spill from Victoria’s share of Hume and Dartmouth allows 200 GL of allocation trade from New South Wales to Victoria. The volume available for trade is updated monthly with each risk of spill announcement. 

Next announcement on risk of spill

The risk of spill in the Murray and Campaspe systems for 2025/26 will be updated on Friday, 10 October 2025.
