About the area

The Condah water supply protection area (WSPA) covers a confined sandstone aquifer to the north of Lake Condah, where it fully underlies the South West Limestone groundwater management area (GMA) and fully overlies the Portland GMA.

The water authority responsible for managing groundwater in the Condah WSPA is Southern Rural Water.

The Condah WSPA Local Management Plan applies to groundwater resources for all formations between 70 m to 200 m below the surface.

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

Response to water availability

Groundwater restrictions

There were no restrictions on licensed use in the Condah WSPA in 2024-25.

Entitlements and use

Groundwater entitlements have been issued for licensed (non-urban) use and urban supply to Macarthur in the Condah WSPA. Groundwater is also available for domestic and stock use.

Entitlement volumes

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 WSPA, the assumed usage is 1.5 ML per bore per year.

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 (7,470 ML) in the Condah WSPA did not exceed the PCV (7,475 ML).

Total volume extracted within available volume

The total volume extracted under licences (3,207 ML) was within the volume available for the year (7,470 ML).
