Final seasonal determination update for 2017/18
The Resource Manager for northern Victoria today announced the final 2017/18 seasonal determinations.
The low-reliability water shares (LRWS) seasonal determination in the Campaspe system increases from 58 per cent to 59 per cent. The Campaspe system also has 100 per cent high-reliability water shares (HRWS).
The seasonal determinations in the Murray, Goulburn and Loddon systems remain unchanged at 100 per cent HRWS. The Broken and Bullarook systems remain at 100 per cent HRWS and 100 per cent LRWS.
Resource Manager Andrew Shields said rain in late March didn’t significantly increase resource availability across northern Victorian systems.
“Actual evaporation and river losses were again lower than estimated in the Campaspe system, which translates to the small seasonal determination increase announced today," Mr Shields said.
"The shortfall to a low-reliability water share seasonal determination in the Murray system is around 370 GL. The shortfall in the Goulburn system is around 770 GL.
“While seasonal determinations against low-reliability water shares in the Murray, Goulburn and Loddon systems were not announced this season, these systems have good reserves for the 2018/19 season. This means each of these systems along with the Campaspe system will receive an opening high-reliability water share seasonal determination on July 2, 2018.”

Trading Opportunities
Allocation trade from New South Wales to Victoria is limited to the lesser of a volume that keeps the risk of spill in the Murray system below 50 per cent (currently 300 GL) or a net annual volume of 200 GL. The trade limit currently allows 200 GL of net trade from New South Wales to Victoria.
Continuing transfers to meet demands in the River Murray downstream of the Barmah Choke means 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.
Allocation trade out of the Broken system closed for this season on March 31, in accordance with the trading rule introduced on July 1, 2014. Trade applications received after March 31 will not be approved. Trade from the Broken system will reopen in early July, as soon as the necessary end of financial year water accounting tasks are completed in the Victorian Water Register. Note the March 31 closing date does not apply to trade within the Broken system or back-trade into the Broken from other systems.
Customers participating in the water trading market can monitor trade availability on the Water Register website. Customers can monitor trading opportunities across the Barmah Choke on the Murray-Darling Basin Authority website.
