Murray system seasonal determinations increase to 100 per cent of high-reliability water shares

Friday 15 November, 2024

The Resource Manager for northern Victoria today updated the 2024/25 seasonal determinations.

The Murray system seasonal determination increases from 98 per cent of high-reliability water shares (HRWS) to 100 per cent HRWS.

The Broken system increases from 45 per cent HRWS to 47 per cent HRWS.

In the Campaspe system, the low-reliability water shares (LRWS) seasonal determination increases from 38 per cent LRWS to 41 per cent LRWS. The Campaspe system also has 100 per cent HRWS.

Seasonal determinations in the Goulburn, Loddon and Bullarook systems are unchanged.  

Resource Manager Mark Bailey said small resource improvements across several areas produced the increased seasonal determinations.

“The flows into the Murray storages, Lake Nillahcootie, and Lake Eppalock were slightly greater than we forecast at the last update,” he said.

“Lower than forecast evaporation and helped increase the amount available for allocation. 

"There is still insufficient water available to make a seasonal determination in the Bullarook system. 

“The deficit is closing. Customers with carryover allocation are able to access that water when needed.”

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

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 100% 0%
Broken 47% 0%
Goulburn 100% 0%
Campaspe 100% 41%
Loddon 100% 0%
Bullarook 0% 0%

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 in the Murray system allows 200 GL of net trade from New South Wales to Victoria.

Customers participating in the water trading market can monitor trade availability on the Water Register website.

Customers can monitor trading opportunities from above the Barmah Choke to downstream of the Choke on the Murray-Darling Basin Authority website
