About the area

  • The West Goulburn Groundwater Management Area (GMA) extends from the Great Dividing Range in the south, to the Murray River in the north. It is located in the Goulburn River Catchment in northern Victoria and is part of the Murray-Darling Basin.
  • Rural centres within the boundary include Kilmore, Broadford, Rushworth, Kyabram, and Barmah.
  • The water authority responsible for managing groundwater in the West Goulburn GMA is Goulburn-Murray Water.
  • The West Goulburn GMA Local Management Plan applies to groundwater up to a depth of 200 m in the area, or 50 m below the base of the Tertiary sediments, whichever is greater.
  • The north of this GMA is overlain by the Shepparton Irrigation Region (SIR) GMA. At this intersection, the SIR GMA applies to groundwater at a maximum depth of 25 m below the ground surface, and the West Goulburn GMA covers groundwater at depths greater than 25 m.
  • This GMA is administered by four management zones: Puckapunyal, Kyabram, Cornella, and Corop Lakes.
  • More information on the GMA can be found on the Goulburn-Murray WaterExternal Link website.

Groundwater restrictions

There were no restrictions on licensed use in the West Goulburn GMA in 2021-22.

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, West Goulburn GMA

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 of the in/out trade of water.

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

Compliance

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

  • entitlement issued: the volume of entitlements issued in the GMU does not exceed relevant PCVs or has not increased without appropriate approvals
  • water extracted: 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

There is no PCV set for the West Goulburn GMA. However, individual management zone limits have been set in the West Goulburn GMA groundwater management plan. The limits are: 1,000 ML for Kyabram Zone; 2,500 ML for Puckapunyal Zone; 500 ML for Cornella Zone; and 500 ML for Corop Lakes Zone (total of 4,500 ML).

Total volume extracted under licences was within the available volume

The total volume extracted under licences (990 ML) was within the volume available for the year (3,332 ML).
