Final 2025/26 seasonal determination update

The Resource Manager for northern Victoria today announced the final seasonal determinations for 2025/26.

The seasonal determinations in the Goulburn and Loddon systems move from 80 per cent of high-reliability water shares (HRWS) to 81 per cent HRWS.

The Broken system increases from 58 per cent HRWS to 64 per cent HRWS.

The Bullarook system increases from 43 per cent HRWS to 48 per cent HRWS.

The Murray and Campaspe systems remain at 100 per cent HRWS.

Resource Manager Mark Bailey said there were small resource improvements due to milder weather conditions and flows into the major storages over the past fortnight.

“Mild temperatures saw lower than estimated evaporation from the storages, while reduced irrigation demand allowed lower release rates and fewer river losses,” Dr Bailey said.

“These factors enabled the increases in the Broken and Bullarook systems announced today.

“Higher than assumed flows into the storages was a factor in the increase for the Goulburn and Loddon systems.

“Today is the final seasonal determination update for 2025/26.

All resource improvements in the remaining months of this water year will contribute to water availability in 2026/27.”

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