July allocations represent the opening allocations for the 2026/27 water year.
Above average rainfall during June was sufficient to generate 24,469 ML of inflow to storages and represented the highest inflow month of the 2025/26 water year. Net evaporation also contributed to a resource improvement with -3,280 ML in net evaporation calculated for system storages.
These improvements were sufficient to post an opening allocation of 12% to Wimmera-Mallee Pipeline Product entitlements. 11 GL was also allocated to the early system reserve. No allocation was possible to Glenelg River Compensation Flow, Recreation, Wetland and Commonwealth Environmental entitlements.

June allocations for the 2025/26 water year have been announced by the Storage Manager.
Above average rainfall during May was sufficient to generate 1,937 ML of inflow to storages and contribute -2,390 ML in net evaporation to the system.
These improvements in addition to an evaporative saving in resource model provided a 6% increase to Wimmera-Mallee Pipeline Product (WMPP) entitlements, which increased to 40% allocation. The Glenelg River Compensation Flow remained at 1% allocation, and no allocation was possible to Recreation, Wetland and Commonwealth Environmental entitlements.
The June resource assessment is the last assessment for the 2025-26 water year. The next assessment will be opening allocations due on 1st July 2026.

May allocations for the 2025/26 water year have been announced by the Storage Manager.
Below average rainfall during April limited inflow to storages with only 125 ML being recorded.
Evaporative saving during April provided a small 1% increase to Wimmera-Mallee Pipeline Product (WMPP) entitlements, which increased to 34% allocation. The Glenelg River Compensation Flow remained at 1% allocation, and no allocation was possible to Recreation, Wetland and Commonwealth Environmental entitlements.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.

April allocations for the 2025/26 water year have been announced by the Storage Manager.
A low-pressure system impacted Victoria between 27th February, and 2nd March providing some moderate falls to headwork storages. Although this system provided some moderate rainfall totals to the system, dry conditions throughout March resulted in limited inflow being recorded to system storages over the assessment period. The most significant benefit received from the rainfall was the offsetting impact it had on storage evaporation over the month. This saving provided a small 1% increase to Wimmera-Mallee Pipeline Product (WMPP) entitlements, which increased to 33% allocation. The Glenelg River Compensation Flow remained at 1% allocation, and no allocation was possible to Recreation, Wetland and Commonwealth Environmental entitlements.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.

March allocations for the 2025/26 water year have been announced by the Storage Manager.
A low-pressure system impacted Victoria between 27th February, and 2nd March providing some moderate falls to headwork storages. Although this system provided some moderate rainfall totals to the system, dry conditions throughout February resulted in limited inflow being recorded to system storages over the assessment period. Inflow received and evaporative saving realised during the assessment period provided a 4% increase to Wimmera-Mallee Pipeline Product (WMPP) entitlements, which increased to 32% allocation. Additionally, the Glenelg River Compensation Flow received 1% allocation. No allocation was possible to Recreation, Wetland and Commonwealth Environmental entitlements.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.

February allocations for the 2025/26 water year have been announced by the Storage Manager.
Limited inflow and high evaporative losses from storages during the resource period limited any improvement in the overall resource position. Wimmera-Mallee Pipeline Product (WMPP) entitlements remain at 28% allocation. Additionally, no allocation was possible to Glenelg River Compensation Flow, Recreation, Wetland and Commonwealth Environmental entitlements.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.

January allocations for the 2025/26 water year have been announced by the Storage Manager.
Limited inflow and high evaporative losses from storages during the resource period limited any improvement in the overall resource improvement. Wimmera-Mallee Pipeline Product (WMPP) entitlements remain at 28% allocation.

December allocations for the 2025/26 water year have been announced by the Storage Manager.
Wimmera-Mallee Pipeline Product (WMPP) entitlements increased from 19% to 28% allocation. Additionally, no allocation was possible to Glenelg River Compensation Flow, Recreation, Wetland and Commonwealth Environmental entitlements.
Above average rainfall and modest inflow during November increased WMPP allocations to 28% for 2025/26 water year. The first stage system reserve of 20 GL was also achieved through the December resource assessment, resulting in all remaining available water going towards entitlement allocations.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.

November allocations for the 2025/26 water year have been announced by the Storage Manager.
Wimmera-Mallee Pipeline Product (WMPP) entitlements increased from 12%to 19% allocation. Additionally, no allocation was possible to Glenelg River Compensation Flow, Recreation, Wetland and Commonwealth Environmental entitlements.
Modest inflow during October helped to increase WMPP allocations to 19% for 2025/26 water year. An additional 6.4 GL of water resource was also secured for the system reserve. The July – October period has historically represented the main inflow period for the system, with 75% of all historical inflow recorded during that period.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.

October allocations for the 2025/26 water year have been announced by the Storage Manager.
Wimmera-Mallee Pipeline Product (WMPP) entitlements increased from 7% to 12% allocation. Additionally, no allocation was possible to Glenelg River Compensation Flow, Recreation, Wetland and Commonwealth Environmental entitlements.
Modest inflow during September helped to increase WMPP allocations to 12% for 2025/26 water year. An additional 3.9 GL of water resource was also secured for the system reserve.
Future increasing in allocation will be contingent on new water entering the system through inflow or realised evaporative / transfer losses on the system less than the assessment provision.
