Seasonal determinations in the Goulburn and Loddon systems remain at 100 per cent of high-reliability water shares, but low-reliability water shares have increased from 40 per cent to 46 per cent.
The Campaspe system stays on 100 per cent HRWS, but moves from 83 per cent LRWS to 100 per cent LRWS.
Seasonal determinations in the Murray, Broken and Bullarook systems remain unchanged.
Resource manager Mark Bailey said resource improvements had enabled seasonal determinations to increase in the Goulburn, Loddon and Campaspe systems.
“Flows into the Goulburn and Campaspe systems since the last assessment have exceeded expected rates,” Dr Bailey said.
“This provided the resource to support the improvements announced today [Friday, December 15].
“There are no deductions from spillable water accounts with today’s update.”
Trading opportunities
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 the Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent.
The spill risk limit allows 200 GL of net trade from NSW to Victoria. The volume available for trade is updated with each risk of spill announcement.
