About the area

  • The Avoca groundwater catchment is in north-western Victoria, and its northern boundary is the Murray River.
  • The groundwater catchment does not contain any groundwater management areas (GMAs) or water supply protection areas (WSPAs): all licence volume is reported as outside management units.
  • Groundwater resources supply licensed entitlements, domestic and stock use, and urban use to Amphitheatre and Redbank.
  • The Avoca groundwater catchment forms 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.

Entitlements and use

Groundwater licence and use volumes in the Avoca groundwater catchment are shown below. Some groundwater licences incorporate domestic and stock use, and in these cases the use is reported in the licensed volume.

The licenced volume used under entitlements must not exceed the volume made available to individual licensed entitlement holders. We report on compliance in the GMU local report pagesExternal Link and the Statewide groundwater pageExternal Link .

Water used

Use in the Avoca groundwater catchment was 959 ML, more than 859 ML in the previous year.

Entitlement volumes

Rights to water in the Avoca 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 2021-22. 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 2 ML usage per bore per year is assumed.

More information on groundwater use and availability has been detailed in the How do we account for groundwaterExternal Link section.

In 2021-22, 959 ML of water was extracted for consumptive purposes, which was more than the 859 ML extracted in the previous year. Of this volume, 894 ML was for non-urban (irrigation) use, 5 ML was for urban use, and 60 ML was estimated to be for domestic and stock use.

There were no restrictions on use in the Avoca groundwater catchment in 2021-22.
