The Murray system seasonal determination increased from 73 per cent of high-reliability water shares to 76 per cent HRWS, while the Goulburn and Loddon systems increased from 89 per cent HRWS to 92 per cent.
The Broken system increased from 17 per cent to 20 per cent HRWS.
In the Campaspe system, the low-reliability water shares seasonal determination increased from 13 per cent to 15 per cent. The Campaspe system also has 100 per cent HRWS.
The Bullarook system remains unchanged at zero per cent HRWS.
Resource manager Mark Bailey said drier conditions in recent weeks meant there was little additional water to allocate.
“Flows into major storages have gradually declined since the last assessment,” he said.
“Those flows remain greater than our conservative estimates, which is the main factor in the seasonal determination increases announced today.
“Further rainfall that creates flows in the catchment areas and into the storages is needed before larger seasonal determination increases are possible.”
The next 2024-25 seasonal determination announcement will be released on Monday, September 2.
The risk of spill in the Murray, Goulburn and Campaspe systems will be updated on Tuesday, September 10.
