About the area
The Moe groundwater catchment is in central Gippsland, east of Melbourne.
The Moe groundwater catchment contains the Moe groundwater management area (GMA). The area not covered by Moe GMA is reported as outside management units.
The Moe GMA straddles this catchment and the Central Gippsland groundwater catchment.
Groundwater resources within the catchment supply licensed entitlements, domestic and stock use, and urban use to Yarragon. Whilst most groundwater licensed in the Moe groundwater catchment is used for irrigation, some is used for dairy-wash purposes.
More information on water management and accounting is detailed in Water explained.
2023-24 overview
Water use
Water used for consumptive purposes was similar to the previous year.
Climate
Rainfall
Less rainfall was received in the Moe groundwater catchment in 2023-24 than the previous year, being close to the long-term average across most of the catchment. Rainfall was below average along the southern border of the catchment.
Figure 1 displays the rainfall received in 2023-24 compared to the long-term average (1975-2024).

Groundwater level trends
In the Accounts, groundwater level trends for groundwater management units (GMUs) have been determined by monitoring data from key bores in the State Observation Bore Network. Trend determinations are made quarterly by comparing each reading to a previous reading in the same season 5 years prior; for example, a summer record is compared to the summer record from 5 years earlier to account for seasonality. These trends are shown in Table 1 below.
Groundwater resources are being actively managed. For more detail on management responses, go to on the Southern Rural Water website.
In 2023-24, the groundwater level trend for the Moe GMA could not be determined towards the end of the year due to data availability, but it was stable in the prior December 2023 quarter.

Response to water availability
Groundwater restrictions
There were no restrictions on licensed groundwater use in 2023-24, the same as previous year.
Entitlements and use
Groundwater licence and use volumes in the Moe groundwater catchment are shown below. Domestic and stock use does not require a licence, so in the Groundwater availability and take table (Table 3), these rows only report water taken.
The licensed volume used under entitlements must not exceed the volume made available to individual licensed entitlement holders. We report on compliance in the GMU local reports and in the Statewide groundwater summary.
Water used
Use in the Moe Groundwater catchment was 888 ML, similar to the 980 ML used in the previous year.
Entitlement volumes
Rights to water in the Moe groundwater catchment are shown below.

Available water and take
The table below shows the total water available and taken under entitlements, and estimated domestic and stock use in 2023-24. Total water available under entitlements is the sum of opening carryover, allocation issued and the net trade in or out of water.
Estimated domestic and stock use is calculated based on an assumed usage per registered bore per year. In this catchment, the assumed usage is 1.5 ML usage per bore per year.
More information on groundwater use and availability has been detailed in How we account for
In 2023-24, 888 ML of water was extracted for consumptive purposes, which was similar to the 980 ML extracted in the previous year. Of this volume, 689 ML was for non-urban (irrigation) use, and 199 ML was estimated to be for domestic and stock use.
