Low Risk of Spill declared in the 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 below the 10 per cent threshold needed to make a low risk of spill declaration.
“Inflows to the storages remained low in September,” Dr Bailey said. “When combined with the water released to meet downstream demand, the risk of spill at Lake Hume and Lake Eppalock has reduced to less than 10 per cent.
“This declaration releases the water held in spillable accounts for use or trade by customers in the Murray and Campaspe systems.”
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.
Next announcement on risk of spill
The next announcement on the risk of spill and its effect on water availability will refer to the 2026/27 water year. A preliminary assessment of the risks of spill for the Murray, Goulburn and Campaspe systems for the 2026/27 season will be released on 15 February 2026. The first formal risk of spill assessment for the 2026/27 season will be announced on Wednesday 1 July 2026.
