About the area

  • The Broken Groundwater Management Area (GMA) is located upstream of Lake Nillahcootie and extends from the Victorian Alps to just south of the Murray River.
  • Rural centres within the boundary include Benalla, Dookie and Tungamah. 
  • The water authority responsible for managing groundwater in the Broken GMA is Goulburn-Murray Water. 
  • The Broken GMA Local Management Plan applies to groundwater resources to a depth of 200 m below ground surface. And includes two management zones; the Broken Sedimentary Plains and the Broken Highlands.
  • More information on the GMA can be found on the Goulburn-Murray WaterExternal Link website.

Groundwater restrictions

There were no restrictions on licensed use for the Broken GMA in 2021-22.

Entitlements and use

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

Entitlement volumes

Available water under licence 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

Entitlement volume did not exceed the PCV

The volume of entitlements (2,976 ML) in the Broken GMA did not exceed the PCV (3,732 ML).

Total volume extracted under licences was within the available volume

The total volume extracted under licences (427 ML) was within the volume available for the year (2,988 ML).
