The Resource Manager for northern Victoria today announced increased 2015/16 seasonal determinations in the Murray, Goulburn, Broken and Loddon systems.
The Broken system has increased from zero per cent to 4 per cent of high-reliability water shares (HRWS).
The Murray system increases by 8 per cent to 76 per cent HRWS. The Goulburn system increases by 3 per cent to 69 per cent HRWS and the Loddon system increases from 50 per cent HRWS to 54 per cent HRWS.
Resource Manager Mark Bailey said the Bullarook system remained unchanged on zero per cent HRWS and the Campaspe system remained unchanged on 50 per cent HRWS.
"Inflows in the Murray and Goulburn storages were greater than assumed for the last assessment. This has led to the increase in the seasonal determinations announced today for these systems," said Dr Bailey.
"The increase in the Broken and Loddon systems came from conditions being slightly better than assumed in our previous assessment.
"The shortfall to making a seasonal determination in the Bullarook system continues to reduce, but inflows into Newlyn Reservoir and Hepburns Lagoon remain very low."
The Goulburn system's inter-valley trade (IVT) account owes about 95 GL to the Murray system on October 1. 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.
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. The spill risk limit allows more than 200 GL of trade, and so the net annual volume of 200 GL applies unless advised otherwise.
Customers participating in the water trading market can monitor trade availability on the Water Register website, waterregister.vic.gov.au/water-trading/allocation-trading.
The Murray-Darling Basin Authority is limiting the trading of water allocations from above the Barmah Choke to downstream to protect the delivery of downstream water entitlements. Customers can monitor trading opportunities across the Barmah Choke on the Murray-Darling Basin Authority website at www.mdba.gov.au/river-data/barmah-choke.
