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.
The latest seasonal allocations for February 2022 have been announced by the Storage Manager.
Despite a series of storm events, no inflow was recorded to reservoirs during January due to catchment areas being very dry. A small improvement in the volume available for allocation resulted from rainfall on reservoirs causing evaporation loss during January to be lower than forecast.
The volume allocated to the System Reserve increased from 12,400 megalitres to 14,150 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.
The latest seasonal allocations for January 2022 have been announced by the Storage Manager.
As a result of very dry conditions and high evaporation losses, no inflow was recorded to reservoirs during December, and there has been no increase to the volume available for allocation this month.
The volume allocated to the System Reserve volume remains at 12,400 megalitres. 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.
Recreational water users are advised to avoid direct contact with water in Lake Lonsdale following the detection of elevated blue-green algae levels. More information.
The latest seasonal allocations for December 2021 have been announced by the Storage Manager.
Total inflow to reservoirs during November was around 2,500 megalitres, or around 19% of average for the month. Inflow combined with lower than forecast evaporation from reservoirs during November has enabled a further 6,200 megalitres to be allocated to the System Reserve. 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. The System Reserve volume is now 12,400 megalitres.
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.
The latest seasonal allocations for November 2021 have been announced by the Storage Manager.
Total inflow to reservoirs during October was 11,930 megalitres, or around 38% of average. This has resulted in allocations for Wimmera-Mallee Pipeline Product entitlements increasing from 53% to 57% this month. Additionally, 6,200 megalitres has been allocated to the System Reserve. 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.
The Glenelg River Compensation Flow entitlement remains at 1% allocation. No allocation has been possible to Recreation, Wetlands or Commonwealth Environmental entitlements.
