Murray Seasonal Determinations Increase to 100 per cent low-reliability water shares

Friday 15 March, 2024

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

Seasonal determinations in the Murray system increase from 100 per cent of high-reliability water shares (HRWS) and 85 per cent of low-reliability water shares (LRWS) to 100 per cent HRWS and 100 per cent LRWS.

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

Resource Manager Mark Bailey said flows into the Murray system were the main contributor to the increase announced today.

“Recent flows in the Murray system have been greater than forecast,” Dr Bailey said.

“The additional water has met demand and enabled the improvement announced today.

“The flows into the Goulburn system have been close to our estimates, providing no scope for improvement to the current seasonal determination.”

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

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 100% 100%
Broken 100% 100%
Goulburn 100% 77%
Campaspe 100% 100%
Loddon 100% 77%
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 Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent. The 200 GL of net trade from New South Wales to Victoria remains available. The volume available for trade is updated with each risk of spill announcement.
