The Murray system seasonal determination increases from 53 per cent of high-reliability water shares to 60 per cent. The Goulburn and Loddon systems increase from 39 per cent to 44 per cent.
The Broken system increases from 0 per cent to 12 per cent.
The Campaspe system remains at 100 per cent. The Bullarook system is unchanged at 0 per cent.
Goulburn-Murray Water resource manager Mark Bailey said recent rainfall provided additional resources to allocate.
“Rainfall across all the catchment areas since the last assessment has increased flows into the storages,” Dr Bailey said.
“The Broken system has received its first allocation for the season, and the seasonal determinations in the Murray, Goulburn and Loddon systems continue to grow.
“There was not enough improvement in the Bullarook system to secure the operating requirements. More rainfall and flows are needed over the coming weeks to close the gap to a seasonal determination.”
Allocation trade from NSW to Victoria is limited to the lesser of a net annual volume of 200 GL or a volume that keeps the risk of spill in Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent.
The current risk of spill from Victoria’s share of Hume and Dartmouth allows 200 GL of allocation trade from NSW to Victoria.
The risk of spill in the Murray and Campaspe systems will be updated on Wednesday, September 10.
The next 2025-26 seasonal determination announcement will be released on Monday, September 15.
