Update of seasonal determinations for 2014/15


Resource Manager for northern Victoria Mark Bailey today announced increased seasonal determinations for the Murray, Broken and Bullarook systems.

The Murray system will increase by six per cent to 96 per cent of high-reliability water shares (HRWS), while the Broken system increases by 27 per cent to 79 per cent HRWS.

The Bullarook system's HRWS remain at 100 per cent and its low-reliability water shares (LRWS) will increase by 40 per cent to 100 per cent.

Seasonal determinations in the Goulburn, Campaspe and Loddon systems stay at 100 per cent HRWS.

"Most catchments are maintaining useful runoff and streamflows, despite below average rainfall being recorded during August. The carryover limits in the Broken system influenced the relatively large increase in that system," Dr Bailey said.

"The Goulburn system is well on the way to establishing the operating reserves needed for next season.

"The shortfall to allocating water to low-reliability water shares is about 140 GL."

Trading opportunities


Allocation trade from New South Wales (NSW) to Victoria is limited to the lesser of a net annual volume of 200 GL or the volume that keeps the risk of spill in the Murray system below 50 per cent.

With the risk of spill in the Victorian Murray system greater than 50 per cent, trade from NSW into Victoria is limited to the volume of trade out of Victoria to NSW. The availability of trade from NSW into the Victorian Murray system will be recalculated on September 10 and the 10th day (or following business day) of each month thereafter.

The volume owed to the Murray system from the Goulburn system's inter-valley trade account is currently above 200 GL. Trade from the Goulburn, Campaspe and Loddon systems to the Victorian Murray, or to NSW and South Australia, is allowed while the total volume owed to the Murray is less than 200 GL.

The volume in the Broken system's inter-valley trade account is currently 1,500 ML. Trade from the Broken system is allowed when the balance of this account is less than 1,500 ML. Further trade opportunities within this limit will be created when the river operator calls out water to meet downstream demand during the season or if there is trade back into the Broken system.

Customers participating in the water trading market are advised that the Murray-Darling Basin Authority has announced that the trading of water allocations from above the Barmah Choke to downstream of the choke will continue in the 2014/15 water year. The Murray-Darling Basin Authority will regularly review the ability to trade across the Barmah Choke and may lift the relaxation at any time during the season if required.

Upcoming Resource Manager announcements
