Small seasonal determination increase for the Bullarook system

Thursday 2 January, 2025

The Resource Manager for northern Victoria today updated the 2024/25 seasonal determinations.

The Bullarook system seasonal determination increases from 5 per cent of high-reliability water shares (HRWS) to 7 per cent HRWS.

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

In the Broken system, seasonal determinations remain at 100 per cent HRWS and 100 per cent of low-reliability water shares (LRWS). The Campaspe system is also unchanged at 100 per cent HRWS and 47 per cent LRWS.

Resource Manager Andrew Shields said there was only a small improvement to water availability.

“While dry conditions have persisted since the last assessment, river operating requirements in the Bullarook system have been lower than estimated,” Mr Shields said. “This enabled the small increase to the Bullarook system seasonal determination.”

The seasonal determinations for northern Victorian water systems on Thursday, 2 January are:

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 100% 0%
Broken 100% 100%
Goulburn 100% 0%
Campaspe 100% 47%
Loddon 100% 0%
Bullarook 7% 0%
