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 Broken system seasonal determination is 100% high-reliability water shares (HRWS) and 40% of low-reliability water shares (LRWS), an increase of 24% LRWS. Campaspe system customers have a seasonal determination of 100% HRWS and 81% LRWS, an increase of 12% LRWS.
The seasonal determinations in the Murray, Goulburn and Loddon systems remain unchanged at 100% HRWS. The Bullarook system seasonal determination also remains unchanged at 100% HRWS and 100% LRWS.
“Resource improvements in the Broken and Campaspe systems over the past fortnight have made the seasonal determination increases announced today possible,” said Dr Mark Bailey, Resource Manager. “In the Murray system water is now being reserved for the 2013/14 season. Large volumes are required for seasonal determinations against LRWS to be announced in the Murray, Goulburn and Loddon systems this season. It is unlikely that any LRWS seasonal determinations will be made this season in these three systems.”
In October, approximately 19,000 ML of the water pre-released from Dartmouth Reservoir could not be stored in Lake Hume. As a result, spillable water accounts in the Murray system will be debited by about 1.6%. Pre-releases from Dartmouth Reservoir are continuing, but the volume stored in Lake Hume will not be confirmed until early December. The risk of spill in the Goulburn and Campaspe systems is also high, with both Lake Eildon and Lake Eppalock above 95% of capacity. Water held in spillable water accounts in these systems is subject to physical spills from the storage or pre-releases.
Upcoming Resource Manager Announcements
- The next assessment of the probability of spill in the Murray, Goulburn and Campaspe systems will be issued on Monday 10 December 2012.
- The next seasonal determination announcement will be issued on Monday 17 December 2012.
