About the area

The Wandin Yallock groundwater management area (GMA) covers a basalt aquifer to the east of Melbourne.

The water authority responsible for managing groundwater in the Wandin Yallock GMA is Southern Rural Water.

The Wandin Yallock GMA Local Management Plan applies to groundwater resources for all formations below the surface.

More information on groundwater management can be found on the Southern Rural Water website.

Response to water availability

Groundwater restrictions

There were no restrictions on licensed use in the Wandin Yallock GMA in 2024-25.

Entitlements and use

Groundwater is available for licensed (non-urban) supply and for domestic and stock use.

Entitlement volumes

Table 2: Groundwater entitlements at 30 June, Wandin Yallock GMA

Use type	2023-24 (ML)	2024-25 (ML)
Licensed use (non-urban)	3,025	3,025
Total	3,025	3,025

Use type	2023-24 (ML)	2024-25 (ML)
Licensed use (non-urban)	3,025	3,025
Total	3,025	3,025

Available water and take

The table below shows the total water available and taken under entitlements, and estimated domestic and stock use in 2024-25. Total water available under entitlements is calculated as the sum of: opening carryover from the prior year (where available), allocation issued during the reporting year, and the net trade in or out of water, across all entitlements. The level of allocation issued is reduced if there are any restrictions in place.

Estimated domestic and stock use is calculated based on an assumed usage per registered bore per year. In this GMA, the assumed usage is 1.5 ML per bore per year.

More information on groundwater use and availability has been detailed in How we account for groundwater.

Compliance

Compliance against water entitlements is reported for this groundwater management unit (GMU) in 2 areas:

entitlement issued: that the volume of entitlements issued in the GMU does not exceed relevant permissible consumptive volumes (PCVs) or has not increased without appropriate approvals
water extracted: that the volume of water taken under entitlements during the year does not exceed the total water available to licence holders.

Key points on compliance against entitlements in 2024-25

Entitlement volume did not exceed the PCV

The volume of entitlements (3,025 ML) in the Wandin Yallock GMA did not exceed the PCV (3,027 ML).

Total volume extracted under licences was within the available volume

The total volume extracted under licences (472 ML) was within the volume available for the year (3,020 ML).
