Seasonal determinations update

Friday 15 December, 2023

The Resource Manager for northern Victoria today updated the 2023/24 seasonal determinations.

Seasonal determinations in the Goulburn and Loddon systems increase from 100 per cent of high-reliability water shares (HRWS) and 40 per cent of low-reliability water shares (LRWS) to 100 per cent HRWS and 46 per cent LRWS.

The Campaspe system moves from 100 per cent HRWS and 83 per cent LRWS to 100 per cent HRWS and 100 per cent LRWS.

Seasonal determinations in the Murray, Broken and Bullarook systems remain unchanged.

Resource Manager Mark Bailey said resource improvements had enabled seasonal determinations to increase in the Goulburn, Loddon and Campaspe systems.

“Flows into the Goulburn and Campaspe systems since the last assessment have exceeded expected rates,” Dr Bailey said.

“This provided the resource to support the improvements announced today.

“There are no deductions from spillable water accounts with today’s update.”

The seasonal determinations for northern Victorian water systems on Friday, December 15 are:

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 100% 16%
Broken 100% 100%
Goulburn 100% 46%
Campaspe 100% 100%
Loddon 100% 46%
Bullarook 100% 100%

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 both Hume and Dartmouth reservoirs below 50 per cent. The spill risk limit allows 200 GL of net trade from New South Wales to Victoria. The volume available for trade is updated with each risk of spill announcement.

The Murray-Darling Basin Authority (MDBA) has announced that trading of water allocations from above the Barmah Choke to downstream of the Choke is restricted to protect the delivery of downstream water entitlements.
