The Storage Manager has realeased its second quarterly operating plan supplement for October to December 2019. This supplement accompanies the Annual Operating Plan and looks specifically at reservoir system operation over the upcoming 3-month period. The Annual Operating Plan and operating plan supplements are available here

The latest seasonal allocations for October 2019 have been announced by the Storage Manager

 

Reservoirs received 7,470 ML of inflow during September, which is around 18% of the September average. Although below average, these inflows have enabled Wimmera-Mallee Pipeline Product allocation to increase by 6% this month to have a 30% allocation. No allocation has yet been possible to Glenelg River Compensation Flow, Recreation entitlement, Wetland entitlement or Commonwealth environmental entitlement.


A October update on Reservoir operations is also now available.

The latest seasonal allocations for September 2019 have been announced by the Storage Manager

 

Around 18,480 ML of inflow was received to reservoirs during August; this has resulted in an allocation increase from 3% to 24% for high reliability entitlement holders. No other allocation announcements have been made.


A Rocklands Reservoir to Taylors Lake transfer of up to 10,000 ML commenced in August and will continue throughout September.

The Storage Manager has started a review of the Storage Management Rules for the for the Wimmera-Glenelg headworks system. The rules form the basis for how the system is operated day-to-day to support water security for the region. Read more or contribute to the review

The latest seasonal allocations for August 2019 have been announced by the Storage Manager

 

Around 16,630 ML of inflow was received to reservoirs during July; this has resulted in an allocation increase from 0% to 3% for high reliability entitlement holders. No other allocation announcements have been made.


A Rocklands Reservoir to Taylors Lake transfer of up to 10,000 ML commenced this month and will continue throughout August.

The latest seasonal allocations for July 2019 have been announced by the Storage Manager. This is the first allocation announcement of the 2019-20 year.

 

Around 8,000 ML of inflow was received to reservoirs during June; however, due to below average inflows over the past two years, further inflows are now required before any allocation can be made to entitlements. Additional inflows are necessary to secure the full headworks system operating water requirement for the 2019-20 year. Operating water meets system losses such as evaporation from reservoirs.


The first allocation announcement for 2019-20 season sees all entitlements receive a 0% allocation. Entitlement holders collectively have access to 116,600 ML of unused water allocation carried forward from 2018-19 year.

The Storage Manager has conducted an assessment of the risk of spill for the system headworks, as per the methodology defined in the Storage Management Rules. The results of this assessment have enabled the Storage Manager to declare a low risk of spill for the 2019-20 water year as of 2 July 2019.

Allocations for June 2019 have been announced by the Storage Manager.

 

Around 2,800 ML of inflow was received to reservoirs during May; the first inflows observed for 6 months.
In response to well below inflow to reservoirs during the 2018-19 season, and a climate outlook which favours dry conditions for 2019-20, entitlement holders collectively agreed that resource improvements during May be held over to help secure system operating water and support allocations in the 2019-20 season. As a result, no increase in allocation has occurred this month.


The final allocation announcement for 2018-19 season sees Wimmera-Mallee Pipeline Product remain at 55% allocation this month, and Glenelg Compensation Flow remain at 1% allocation. No allocation has been possible to Recreation entitlement, Wetland entitlement or Commonwealth environmental entitlement during 2018-19.

Allocations for May 2019 have been announced by the Storage Manager.

 

No measureable inflow was observed to reservoirs for a sixth consecutive month during April. With continued dry conditions and little rainfall during April, losses from the reservoir system have again matched the Storage Manager’s projections. As a result, no increase in allocation has been possible for May.

 

Wimmera-Mallee Pipeline Product remains at 55% allocation this month. Glenelg Compensation Flow remains at 1% allocation. No allocation has yet been possible to Recreation entitlement, Wetland entitlement or Commonwealth environmental entitlement.

 

Allocations for April 2019 have been announced by the Storage Manager.

 

No measureable inflow was observed to reservoirs for a fifth consecutive month during March. With generally dry conditions and little rainfall during March, losses from the reservoir system have matched the Storage Manager’s projections. As a result, no increase in allocation has been possible for April.

 

Wimmera-Mallee Pipeline Product remains at 55% allocation this month. Glenelg Compensation Flow remains at 1% allocation. No allocation has yet been possible to Recreation entitlement, Wetland entitlement or Commonwealth environmental entitlement.
