The Victorian Murray system increases from 73 per cent of high-reliability water shares to 80 per cent HRWS.
The Goulburn and Loddon systems increase from 47 per cent HRWS to 51 per cent HRWS, while the Broken system lifts from 17 per cent HRWS to 22 per cent HRWS.
The Campaspe system remains at 100 per cent HRWS, and the Bullarook system is unchanged at zero per cent HRWS.
No system has a low-reliability water share allocation.
Northern Victoria resource manager Mark Bailey said the allocation improvements came from continued flows into the major storages.
“Rainfall since the last update has kept the flows into the storages above our conservative estimates,” Dr Bailey said.
“This provided additional water for allocation.
“As the Goulburn seasonal determination is now above 50 per cent HRWS, the early season reserve is now fully established. All resource improvements will now contribute to seasonal determination increases.
“There continues to be small improvements in the Bullarook system but not enough to secure the operating requirements.
“More rainfall and flows are needed to close the gap to a seasonal determination.”
The next 2025-26 seasonal determination announcement will be released on Wednesday, October 15.
NSW water allocations
General security licences in the NSW Murray system have received an allocation increase of eight per cent of their entitlement.
The eight per cent increase brings the cumulative general security allocation for the 2025-26 water year to 18 per cent.
This brings the current balance of general security water to 850 Gl or an average of 51 per cent of entitlement.
The NSW Department of Climate Change, Energy, the Environment and Water says individual balances may be higher or lower than this percentage subject to their water use decisions.
The department said the improved water resources come largely from recent inflows to the storages.
The assessment is based on NSW’s share of storage volumes as at the end of August and observed inflows up to September 23.
