Seasonal determination increases for the Goulburn, Broken and Loddon systems

The Resource Manager for northern Victoria today announced an update of 2025/26 seasonal determinations.

Seasonal determination in the Goulburn and Loddon systems increase from 62 per cent of high-reliability water shares (HRWS) to 66 per cent HRWS.

The Broken system increases from 37 per cent HRWS to 39 per cent HRWS.

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

 The Bullarook system is unchanged at 0 per cent HRWS.

 Resource Manager Mark Bailey said rainfall had provided the resource improvements needed for allocation.

 “The scattered rainfall across the catchments since the last update has kept water flowing into the storages,” Dr Bailey said. “This has provided the seasonal determination improvements announced today.

 “There is almost enough resource in the Bullarook system to begin allocating water for the first time this season. Flows into the storages and lower operating requirements have continued to close the gap to a seasonal determination.

 “The improved resource positions in the Murray and Campaspe will help availability in the 2026/27 water year in those systems.”

 The seasonal determinations for northern Victorian water systems on Monday 1 December are:

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 100% 0%
Broken 39% 0%
Goulburn 66% 0%
Campaspe 100% 0%
Loddon 66% 0%
Bullarook 0% 0%
