The latest seasonal allocations for October 2022 have been announced by the Storage Manager.
Inflow to reservoirs during September was approximately 121% of average, with the total volume in storage having increasing by around 54,000 megalitres since the September water allocation assessment. This has enabled a substantial increase to allocations, with Wimmera-Mallee Pipeline Product entitlements increasing from 19% to 60% this month. Glenelg River Compensation Flow has received a 4% allocation, with Recreation and Wetlands entitlements both receiving a 2% allocation. No allocation has been possible yet to Commonwealth Environmental entitlements.
A revised system reserve rule came into effect in August 2022. A total of 20,000 megalitres has been allocated to the system reserve. Details of the new reserve rule are available from the Storage Management Rules page.
The Wimmera-Glenelg Headworks Storage Manager began releasing 300 megalitres of water from Lake Wartook into the MacKenzie River this morning in anticipation of the reservoir spilling.

The latest seasonal allocations for September 2022 have been announced by the Storage Manager.
Inflow to reservoirs during August was approximately 66% of average, with the total volume in storage having increasing by around 42,500 megalitres since the August water allocation assessment. This has supported an increase in allocation to Wimmera-Mallee Pipeline Product entitlements from 2% to 19% this month. No allocation has been possible yet to Glenelg River Compensation Flow, Recreation, Wetlands or Commonwealth Environmental entitlements.
A revised system reserve rule came into effect in August 2022. A total of 17,130 has been allocated to the system reserve. Details of the new reserve rule are available from the Storage Management Rules page.
The latest seasonal allocations for August 2022 have been announced by the Storage Manager.
Inflow to reservoirs during July was approximately 13% of average, with reservoirs increasing by around 6,000 ML since the July water resource assessment. This has been sufficient for a 2% allocation to be made to Wimmera-Mallee Pipeline Product entitlements this month. No allocation has been possible yet to Glenelg River Compensation Flow, Recreation, Wetlands or Commonwealth Environmental entitlements.
A revised system reserve rule came into effect this month, with 2,200 megalitres now in reserve. The revised rule shares the available water between entitlements and the system reserve as soon as allocations commence. Details of the new reserve rule are available from the Storage Management Rules page.
The latest seasonal allocations for July 2022 have been announced by the Storage Manager. This is the first allocation announcement of the 2022-23 year.
Sufficient water is held in storage to secure all headworks system operating water requirements for the 2022-23 season. However, further inflow is required before any allocation can be made to entitlements. Operating water represents the volume which is projected to be lost through the normal operation of the headworks system. Evaporation from reservoirs represents the majority of system operating water requirements.
While no allocation has been possible to any entitlement at the time of the July 2022 water resource assessment, bulk entitlement holders collectively have access to approximately 109,000 megalitres of unused water allocation carried forward from 2021-22 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 2022-23 water year as of 1 July 2022.
The latest seasonal allocations for June 2022 have been announced by the Storage Manager. This is the final allocation announcement for the 2021/22 season.
The month of May saw below average rainfall recorded at all reservoirs. A further small improvement in the volume available for allocation resulted from lower than forecast evaporation from reservoirs, combined with a very small volume of inflow.
This resource improvement has enabled allocations to Wimmera-Mallee Pipeline Product entitlements to increase from 59% to 63%. Glenelg River Compensation Flow entitlement allocation increased from 3% to 7%. Recreation entitlement increased from 1% to 5% allocation, and Wetlands entitlement increased from 1% to have a 6% allocation. No allocation has been possible to Commonwealth Environmental Water Holder entitlements this season. The volume allocated to the System Reserve remains at 15,000 megalitres.
The latest seasonal allocations for May 2022 have been announced by the Storage Manager.
The month of April again saw below average rainfall recorded at most reservoirs. A small improvement in the volume available for allocation resulted from lower than forecast evaporation from reservoirs, combined with a very small volume of inflow.
This resource improvement has enabled allocations to Wimmera-Mallee Pipeline Product entitlements to increase from 58% to 59%. Glenelg River Compensation Flow entitlement allocation increased from 2% to 3%. Recreation and Wetlands entitlements have both received a 1% allocation this month. No allocation has been possible to Commonwealth Environmental Water Holder entitlements. The volume allocated to the System Reserve remains at 15,000 megalitres.
The latest seasonal allocations for April 2022 have been announced by the Storage Manager.
The month of March was dry, with below average rainfall recorded at all reservoirs. A small improvement in the volume available for allocation resulted primarily from a reduction in forecast headworks system losses from April until the end of June 2022.
The volume allocated to the System Reserve increased from 14,500 megalitres to 15,000 megalitres this month. The resource improvement also enabled allocations to Wimmera-Mallee Pipeline Product entitlements to increase from 57% to 58%. Glenelg River Compensation Flow entitlement allocation increased from 1% to 2%. No allocation has been possible to Recreation, Wetlands or Commonwealth Environmental Water Holder entitlements.
The latest seasonal allocations for March 2022 have been announced by the Storage Manager.
The month of February was very dry, with below average rainfall recorded at all reservoirs. A very small improvement in the volume available for allocation resulted from evaporation during February being slightly lower than the Storage Manager’s conservative estimate.
The volume allocated to the System Reserve increased from 14,150 megalitres to 14,500 megalitres this month. Bulk entitlement rules require a total of 15,000 megalitres to be allocated to the System Reserve once Wimmera-Mallee Pipeline Product entitlements reach 57% allocation. Allocations for Wimmera-Mallee Pipeline Product entitlements remain at 57% this month, and the Glenelg River Compensation Flow entitlement remains at 1% allocation. No allocation has been possible to Recreation, Wetlands or Commonwealth Environmental entitlements.
