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,” he said.
Meanwhile, allocation trade from NSW to Victoria is limited to the lesser of a net annual volume of 200GL 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 200GL of allocation trade from NSW to Victoria. The volume available for trade is updated monthly with each risk of spill announcement.
The risk of spill in the Murray and Campaspe systems for 2025/26 will be updated on Friday, October 10.
