Rural customers are reminded that the 2021/2022 irrigation season ends on 30 June 2022.


The maximum allocation that can be carried over into the following season (2022/2023) is the total volume of Water Shares associated to your Allocation Account balance (ABA). Anything over that will be automatically written off. To avoid write-off, it is recommended you trade any volume of allocation at risk.


This year the Victorian Water Register will close at midday (12.00 pm AEST) on 30 June 2022 and reopen at midnight (12.00 am AEST) on 1 July 2022 for the end of year accounting that enables the roll over from the 2021-22 to the 2022-23 water year.


Important dates to remember for allocation trade applications are:


Friday 17 June 2022, 4:30PM
Interstate trade applications require the approval of both states.
Applications received after this date and time are not guaranteed to be processed in the 2021/2022 year.


Friday 24 June 2022, 4:30PM
Allocation trades within Victoria that are submitted online to be processed by LMW must be submitted by this date and time.
Applications received after this date and time are not guaranteed to be processed in the 2021/2022 year.


Thursday 30 June 2022, 12:00PM
Applications to trade allocation within Victoria, made via the Broker Portal or ‘My Water’ portal, may be submitted for instant processing until this date and time.

Carryover is the opportunity to carry unused allocation from one season to the next for use or trade, particularly in dry seasons when the seasonal determination may be less than 100%.

It is important to understand that carryover is recorded against Water Shares, not your allocation account (ABA). To carryover water you must have a Water Share associated to the ABA.

The Water Share can be either High Reliability or Low Reliability, but carryover is recorded against your Low Reliability Water Shares first.

On 30 June each year, any allocation remaining in an allocation account (ABA) is automatically carried over into the new season up to the total volume of Water Shares (entitlement) associated to the ABA. Any allocation above that volume will automatically be written-off. Carryover water is subject to a 5% reduction to cover evaporation losses in the storages. On 1 July each season this net carryover (after the 5% deduction) is available in your ABA for use or trade.

Once a ‘Low Risk of Spill Declaration’ is made by the Northern Victoria Resource Manager, any allocation remaining in ABA spill accounts is returned to the ‘available balance’ of the ABA for use or trade. Any allocation returned attracts an additional GMW storage charge on that volume. This is called an Above Entitlement Storage fee which is due later in the season.


Note: Any allocation that instead has ‘spilled’ is not subject to this charge.

Please be advised Lower Murray Water (LMW) is required to enter final meter readings for the 2021/22 irrigation season into the Victorian Water Register by 5pm Wednesday 29 June.


Where possible, we encourage you to finalise water use and irrigation by Tuesday 28 June to allow for telemetry transmissions and last-minute readings to be recorded.


Final meter readings are collected via automatic and manual methods progressively throughout the month of June. Any water used after final meter readings have been recorded will be deemed usage from your 2022/23 irrigation season allocation, unless you contact us to update your reading.


We encourage you to monitor your June readings and ensure they are consistent with the data recorded on the LMW online water ordering site.


If you wish to update your meter reading, please contact us on 03 5051 0795 before 4pm Tuesday 28 June.

The Northern Victorian Resource Manager has released the first outlook of the 2022/23 season.
Resource Manager Dr Mark Bailey said the reserves built so far in 2021/22 had laid strong foundations for 2022/23.

“The Murray, Goulburn, Campaspe and Loddon systems have reserves available for 2022/23,” Dr Bailey said.

“Based on estimated use to the end of the season, opening seasonal determinations in the Murray system are likely to be around 80 per cent of high‑reliability water shares (HRWS).

“In the Goulburn, Campaspe and Loddon systems, the opening seasonal determinations are expected to start at about 50 per cent HRWS. That’s under our dry outlook category, which is much drier than current catchments conditions.”

Fewer reserves are available in the Broken and Bullarook systems, which have a lower entitlement to storage ratio.

“Carried over allocation volumes and catchment conditions will influence early season availability in the Broken and Bullarook systems,” Dr Bailey added.

“Average inflow conditions should see all of the northern Victorian systems reach seasonal determinations of 100 per cent HRWS by mid-October 2022.”

The Resource Manager used climate-adjusted flow records and assumptions about water use to the end of the water year to determine the initial risk of spill in the Murray, Goulburn and Campaspe systems.

“The Murray system risk of spill in 2022/23 is currently about 80 per cent,” Dr Bailey said.

“The risk is around 60 per cent in the Goulburn and about 40 per cent in the Campaspe system.

“Customers in these systems should factor the risk of spill into their plans for the remaining months of 2021/22.”

The first 2022/23 seasonal determination announcement will be released on Friday 1 July 2022 and will include an updated outlook and an assessment of the probability of spill in the Murray, Goulburn and Campaspe systems.

To ensure infrastructure continues to function well when customers need it most, LMW undertakes scheduled maintenance during winter while demand is low. As a result of these works, short interruptions to rural water supply are sometimes necessary in irrigation districts.


Maintenance works range from channel lining and patching, to electrical works and irrigation main replacement, and any major interruptions are outlined on the winter maintenance pumping schedule to assist rural customers with planning irrigation or managing storage levels. It’s important to note the schedule is subject to change.


Affected rural customers will be notified via SMS with up-to-date information when works are due to commence. You can register to receive SMS updates by updating your contact details in WaterNow at waterorder.lmw.vic.gov.au


Winter maintenance pumping schedules have been emailed to rural customers and are also available on our website. If you wish to receive email service updates, contact any LMW office and provide your current email address.

Murray–Darling Basin Authority (MDBA) and Goulburn-Murray Water (GMW) announced that essential maintenance works will be conducted at the Mildura Weir from Monday 20 July, which will involve lowering the river level in the weir pool and closing Lock 11. Works are expected to take three weeks to complete, including six days to lower the weir pool and six days to refill it.


“It is critical that river infrastructure is kept in the best possible condition to protect workers and visitors and to support the communities and industries that depend upon the reliable operation of the river,” MDBA Acting Executive Director River Management, Dr Andrew Kremor said.


“We understand the river is always in demand to meet a variety of needs so there is never a perfect time to conduct works. The Murray River is vital to the region’s economy and recreation, and it is crucial to complete the works before the irrigation season begins.”


“We have scheduled the works for mid-winter following consultation with tourism operators, irrigators, the Mildura Rural City Council and the Wentworth Shire Council.”


GMW’s General Manager Water Storage Services, Martina Cusack said the works would take three weeks to complete, including six days to lower the weir pool and six days to refill it.


“We will be replacing three of the trestles that control the flow of water through the weir. The last time new trestles were installed at the Mildura weir was in 2016,” Mrs Cusack said.


“This year we expect the river levels upstream of the weir to drop by approximately 3.5 metres, exposing some of the riverbank which is usually submerged.


MDBA and GMW encourage boat operators, river pumpers and other river users to take the lowering of the weir pool and lock closure into account when planning their activities on the river.
