Further Information

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

Seasonal Allocations

The seasonal allocation in the Murray system is 33% of high-reliability water shares (HRWS), which is an increase of 12%. The seasonal allocation in the Goulburn and Loddon systems increased by 12% to be 60% HRWS. The Broken system seasonal allocation rose by 2% to 20% HRWS.

The Bullarook system seasonal allocation has increased from 39% HRWS to be 100% HRWS and 100% of low-reliability water shares (LRWS).

The seasonal allocation in the Campaspe system is unchanged at 100% HRWS and 47% LRWS.

"The improvements in the seasonal allocations for the Murray and Goulburn systems came from higher than anticipated storage inflows," said Dr Mark Bailey, Resource Manager. "The catchments in the north-east ranges are quite wet and responded well to the recent rainfall. There was a good response in the Bullarook Creek catchment, which allowed a large improvement to the allocation in that system."

"The Goulburn system has also benefited from the releases currently occurring at Lake Eildon," said Dr Bailey. "There has been approximately 66,300 megalitres released from Lake Eildon since 1 July. This has caused the volumes held in Goulburn spillable water accounts, the Goulburn inter-valley trade account, and Living Murray environmental entitlements to be each debited by approximately 11%. The spilled volume has been reassigned to the resources available for allocation."

"The Lake Eildon releases are continuing, so additional volumes will be debited from the three accounts at the next allocation update," added Dr Bailey.
