2026/27 Risk of Spill update for Murray and Campaspe systems
The Resource Manager for northern Victoria today updated the 2026/27 risk of spill information for the Murray and Campaspe systems.
Resource Manager Mark Bailey said the risk of spill in both systems remained above the 10 per cent threshold needed to make a low risk of spill declaration.
“Inflows have filled Lake Eppalock to capacity,” Dr Bailey said. “The lake is effectively spilling, which means Campaspe spillable water accounts will be reduced by the volume of spill.
“The quantity deducted from the Campaspe spillable water accounts will be confirmed in the September 15 seasonal determination announcement.
“Despite rising water levels at Lake Hume, the risk of spill in the Murray system remains about 45 per cent because of potential demand over coming months.”
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 risk of spill from Victoria’s share of Hume and Dartmouth is approaching 50 per cent, and 55 GL of allocation trade from New South Wales to Victoria is available. The volume available for trade is updated monthly with each risk of spill announcement.
