Murray seasonal determinations for 2023/24 increase to 100 per cent
The Resource Manager for northern Victoria today announced an update of 2023/24 seasonal determinations.
The Murray system seasonal determination increases from 90 per cent of high-reliability water shares (HRWS) to 100 per cent HRWS.
The Broken system moves from 53 per cent HRWS to 72 per cent HRWS.
The Campaspe system increases from 100 per cent (HRWS) and 62 per cent of low-reliability water shares (LRWS) to 100 per cent HRWS and 63 per cent LRWS.
Seasonal determinations in the Goulburn, Loddon and Bullarook systems remain unchanged.
Resource Manager Mark Bailey said redistributions of the stored resources contributed to the increases announced today.
“Deductions from spillable water accounts produced the increased seasonal determinations in the Murray and Campaspe systems,” Dr Bailey said.
“The improvement in the Broken system came from reduced loss commitments for the season.
“About 165 gigalitres will be deducted from Murray spillable water accounts today, which is 28 per cent of the overall volume.
“The deducted volume in the Campaspe system is about 1 gigalitre or 4 per cent the volume in spillable accounts.”
“Approximately 21 gigalitres, or 5 per cent, will be deducted from Goulburn spillable water accounts,” Dr Bailey added.
“Releases to manage the rate of fill from Lake Eildon are not required at present and further deductions will only occur if Goulburn-Murray Water resumes filling management operations.”

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 the Victoria’s share of the both Hume and Dartmouth reservoirs below 50 per cent. As Victoria’s share of Hume and Dartmouth is close to full, trade from New South Wales to Victoria is not possible. The volume available for trade is updated with each risk of spill announcement.
