About the area
The Upper Murray groundwater catchment is in north-eastern Victoria. It extends from the Victorian Alps to the Murray River.
The groundwater catchment contains the Upper Murray and Kiewa groundwater management areas (GMAs).
Groundwater resources within the catchment supply licensed entitlements, domestic and stock use, and urban use to Dinner Plain.
The groundwater catchment is part of the Murray-Darling Basin, and groundwater management arrangements are subject to the requirements of the Murray-Darling Basin Plan.
More information on water management and accounting is detailed in Water explained.
2022-23 overview
Urban supply
Groundwater supplied to 1 town in the catchment.
Water use
More water was used for consumptive purposes than the previous year.
Climate
Rainfall
Rainfall received in the Upper Murray groundwater catchment in 2022-23 was similar to the previous year, being very much above the long-term average across most of the catchment. Rainfall was:
- the highest recorded in the reference period (1975 to 2023) near Glen Valley and an eastern portion along the border
- very much above average in most of the catchment
- above average only in the south of the catchment, around Omeo.
Figure 1 displays the rainfall received in 2022-23 compared to the long-term average (1975-2023).

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.
Groundwater resources are being actively managed. For more detail on management responses, go to on the Goulburn-Murray Water website.
In 2022-23, groundwater level trends for the Kiewa and Upper Murray GMAs were rising towards the end of the year.

Entitlements and use
Groundwater licence and use volumes in the Upper Murray groundwater catchment are shown below. Domestic and stock use does not require a licence, so in the Groundwater availability and use table, 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 Statewide groundwater.
Water used
Use in the Upper Murray groundwater catchment was 1,589 ML, more than the 1,438 ML used in the previous year.
Entitlement volumes
Rights to water in the Upper Murray groundwater catchment are shown below.

Available water and use
The table below shows the total water available and used under entitlements, and estimated domestic and stock use in 2022-23. 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 2 ML usage per bore per year.
More information on groundwater use and availability has been detailed in How we account for .
In 2022-23, 1,589 ML of water was extracted for consumptive purposes, which was more than the 1,438 ML extracted in the previous year. Of this volume, 707 ML was for non-urban (irrigation) use, 74 ML was for urban use, and 808 ML was estimated to be for domestic and stock use.
There were no restrictions on use in the Upper Murray groundwater catchment in 2022-23.
