Seasonal Determination - 1 October 2024

Small seasonal determination increases for Murray and Broken systems

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

The Murray system seasonal determination increases from 88 per cent of high-reliability water shares (HRWS) to 89 per cent HRWS.

The Broken system increases from 29 per cent HRWS to 31 per cent HRWS.

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

Resource Manager Mark Bailey said there had been little improvement in the volume available to support seasonal determinations.

“The small increases in the Murray and Broken systems came from higher than estimated flows into the storages and in the tributaries downstream of storages,” he said.

“Elsewhere, actual flows were near to our estimates and did not contribute additional resource.

“In the Bullarook system, more flow into the storages is needed before a seasonal determination can be made. The gap is closing and will close more quickly with further rainfall in the system. Customers with carryover allocation can access their water when needed.”

The seasonal determinations for northern Victorian water systems on Tuesday, 1 October are:

 

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 89% 0%
Broken 31% 0%
Goulburn 100% 0%
Campaspe 100% 25%
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. As the risk of spill from Victoria’s share of Hume and Dartmouth is currently greater than 50 per cent, allocation trade from New South Wales to Victoria is not possible. The volume available for trade is updated monthly with each risk of spill announcement.
