The Resource Manager for northern Victoria today announced increases to seasonal determinations in all systems – except the Bullarook system which is already at 100 per cent.
The Murray system increases by 10 per cent to 61 per cent of high-reliability water shares (HRWS) and the Goulburn system increases by 11 per cent to 57 per cent HRWS.
The Campaspe system moves from 48 per cent to 70 per cent HRWS and the Loddon system moves from 25 per cent to 57 per cent HRWS.
The Broken system increases from 54 per cent to 100 per cent HRWS.
The Bullarook system remains unchanged at 100 per cent HRWS and 100 per cent low-reliability water shares (LRWS).
Resource Manager Mark Bailey said rainfall continued to increase water resource availability across northern Victoria.
“The catchments are still producing useful flows when it rains,” said Dr Bailey.
“Lake Eppalock and the storages in the Loddon system have received good inflows since the last update of seasonal determinations.
“With the seasonal determinations rising above 50 per cent in the Goulburn system, the early season reserves for 2017/18 in both the Murray and Goulburn systems are fully established.” Dr Bailey said.
Dr Bailey also confirmed the Murray-Darling Basin Authority had started pre-releasing water from Lake Hume on August 29 to manage the storage volume ahead of forecast inflows.
“The Lake Hume pre-releases mean water will be deducted from spillable water accounts in the Murray system,” said Dr Bailey. “The timing and volume of the deductions depends on the volume and duration of the pre‑releases. More information will be provided with the next seasonal determination update on September 15.”

Trading Opportunities
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 since August 1, 2016.
Trading opportunities from New South Wales to Victoria are next updated on September 12, 2016.
The Goulburn system’s inter-valley trade (IVT) account now owes about 145 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.
The trading of water allocations from above the Barmah Choke to downstream of the Barmah Choke is restricted to protect the delivery of downstream water entitlements. Customers can monitor trading opportunities across the Barmah Choke on the Murray-Darling Basin Authority website. Trade from upstream of the Barmah Choke to downstream is restricted to backtrade, which is the volume of allocation trade from downstream of the Barmah Choke to upstream.
