Further Information
The Resource Manager for northern Victorian regulated water systems today announced an update to the seasonal determinations for the 2012/13 season.
The Murray system seasonal determination is 95% of high-reliability water shares (HRWS), an increase of 14%. The Broken system seasonal determination has increased by 53% to be 100% HRWS. Campaspe system customers have a seasonal determination of 100% HRWS and a seasonal determination of 68% of low-reliability water shares (LRWS), an increase of 1% LRWS.
The seasonal determination in the Goulburn and Loddon systems remains unchanged at 100% HRWS. The Bullarook system seasonal determination also remains unchanged at 100% HRWS and 100% LRWS.
“The use of unregulated flows downstream of the Murray storages to meet irrigation demand has increased the volume of water available in storage to make seasonal determinations. An increase in tributary flows from rainfall over the past week has also contributed to the change in the Murray system announced today.” said Dr Mark Bailey, Resource Manager.
“Seasonal determinations in the Murray system are expected to increase to 100% HRWS by 15 November even under dry conditions.” Dr Bailey added.
The relatively large change in the Broken system is because of the effects of its carryover rules and the volumes its customers have carried over into this season.
Storages in the Murray, Goulburn and Campaspe systems are all above 98% of capacity. Water held in spillable water accounts in these systems is subject to physical spills from the storage or pre-releases. The risk of spill from Dartmouth Reservoir, Lake Eildon and Lake Eppalock remains high. In the past fortnight, approximately 5,000 ML has been pre-released from Lake Eildon.
Upcoming Resource Manager Announcements
The next seasonal determination announcement will be issued on Thursday 1 November 2012.
The next assessment of the probability of spill in the Murray, Goulburn and Campaspe systems will be issued on Monday 12 November 2012.
