The Resource Manager for northern Victoria today announced updates to the 2017/18 seasonal determinations.
The Murray system remains unchanged at 66 per cent of high-reliability water shares (HRWS).
The Goulburn system and the Loddon system increase from 36 per cent to 40 per cent HRWS.
The Campaspe system remains unchanged at 100 per cent HRWS.
The Broken system increases from 3 per cent to 6 per cent HRWS and the Bullarook system increases from 16 per cent to 32 per cent HRWS.
Resource Manager Mark Bailey said recent rainfall had increased water availability in the Goulburn, Loddon, Broken and Bullarook systems.
“The catchments are responding to rain,” Dr Bailey said.
“The soils are wetter and rain is turning into runoff more quickly than in recent weeks.
“However, the flows into the major storages are still well below average for this time of year. Further rain is needed for more runoff, greater volumes in storage, and larger seasonal determination increases.”
Dr Bailey added that Bureau of Meteorology seasonal outlooks indicated a drier spell was likely for northern Victoria.
“Rainfall in the period August to October, which covers the period of highest average flow into the major storages, is likely to be less than average across most of Victoria,” he said.
Dr Bailey advised entitlement holders to use the weather information and seasonal determination outlooks to plan their water needs in 2017/18.
The seasonal determinations for northern Victorian water systems on Tuesday, August 1 are:
Allocation trade from New South Wales 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 Murray system below 50 per cent. As the risk of spill in the Murray system is above 50 per cent, trade from New South Wales to Victoria is limited to the volume traded from Victoria to New South Wales.
Trading opportunities from New South Wales to Victoria are next updated on August 10, 2017.
The Goulburn system’s inter-valley trade (IVT) account owes about 200 GL to the Murray system. The Goulburn, Campaspe and Loddon systems can trade to the Victorian Murray system, New South Wales and South Australia while the total volume owed to the Murray system is less than 200 GL.
The Goulburn, Campaspe and Loddon systems can trade from the Victorian Murray system, New South Wales and South Australia while the total volume owed to the Murray system is greater than zero.
Customers participating in the water trading market can monitor trade availability on the Water Register website. Additional information about how trade opportunities are calculated has recently been added to the allocation trading page.
The Murray-Darling Basin Authority (MDBA) has announced that trading of water allocations from above the Barmah Choke to downstream of the Choke is restricted to protect the delivery of downstream water entitlements. Customers can monitor trading opportunities across the Barmah Choke on the MDBA website.
