Final seasonal determination update for 2024/25

The Resource Manager for northern Victoria today provided the final 2024/25 seasonal determination update.

The Bullarook system seasonal determination increases from 14 per cent of high-reliability water shares (HRWS) to 19 per cent HRWS.

Seasonal determinations in the Murray, Goulburn and Loddon systems remain at 100 per cent HRWS.

The Campaspe system seasonal determination is unchanged at 100 per cent HRWS and 48 per cent low‑reliability water shares (LRWS).

In the Broken system, seasonal determinations remain at the maximum available 100 per cent HRWS and 100 per cent LRWS.

Resource Manager Mark Bailey said weather conditions and system operations had improved water availability in the Bullarook system.

“Rainfall over the Bullarook storages and lower than forecast operating requirements meant there was more water available for allocation,” Dr Bailey said.

“As today is the final seasonal determination update for 2024/25, resource improvements in the remaining months will contribute to reserves for 2025/26 seasonal determinations.”

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

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.
