Further Information

The Resource Manager for northern Victorian regulated water systems today updated the seasonal allocations for 2011/12.

The seasonal allocation in the Murray system is now 61% of high-reliability water shares (HRWS), which is an increase of 11% HRWS. The seasonal allocation in the Goulburn and Loddon systems increased by 8% HRWS to be 87% HRWS. The Broken system seasonal allocation increased by 2% HRWS to be 36% HRWS and the seasonal allocation in the Campaspe system is 100% HRWS and 91% of low-reliability water shares (LRWS), an increase of 37% LRWS.

The Bullarook system seasonal allocation remains unchanged at 100% HRWS and 100% LRWS.

“Today’s allocation increases have been made possible by inflows which increased after rain in mid August,” said Graeme Hannan, Resource Manager. “As the storages are close to full, much of the inflow will not be stored and cannot be fully used to support additional allocation increases. With large volumes of water being carried over in all systems, water availability this season is already very high.”

“Since 15 August, some minor releases have been made from Lake Eildon under the target filling arrangements and there has been about 21,000 ML above the minimum requirements released from Goulburn-Murray Water’s share of Lake Eppalock. Less than 1% has been debited from Goulburn spillable water accounts, the Goulburn inter-valley trade account, and Living Murray environmental entitlements while approximately 44% has been debited from the corresponding Campaspe accounts,” said Mr Hannan.

Customers participating in the water trading market are reminded that the Murray-Darling Basin Authority has relaxed the rule controlling allocation trade from upstream of the Barmah Choke to downstream users. The ability to trade across the Barmah Choke will be regularly reviewed by the Murray-Darling Basin Authority and the relaxation may be lifted at any time during the season.

The next allocation announcement and updated outlooks will be issued on Thursday 15 September 2011.

A risk of spill assessment for the Goulburn and Campaspe systems will be issued on Monday 12 September 2011.
