Resource Manager Andrew Shields said recent flows into the storages had increased the risk of spill in both the Murray and Campaspe systems.
“Above-average inflows to Lake Hume and Lake Eppalock during June increased the volume of water in storage,” Mr Shields said.
“The risk of spill is now 35 per cent in the Murray system and 50 per cent in the Campaspe system.”
Mr Shields 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.
The risk of spill in the Murray and Campaspe systems in 2026-27 will be updated on Monday, August 10.
