About the area

The Katunga Water Supply Protection Area (WSPA) is located to the north of the Great Dividing Range and incorporates parts of the floodplains of the Murray River, Broken Creek and the Goulburn River.

Rural centres within the WSPA boundary include Strathmerton, Cobram, Numurkah and Nathalia.

The water authority responsible for managing groundwater in the Katunga WSPA is Goulburn-Murray Water.

The Katunga WSPA Groundwater Management Plan applies to groundwater at depths from 25 m below the surface to either 50 m into bedrock, or 200 m from the surface, whichever is greater.

More information on the WSPA can be found on the Goulburn-Murray Water website.

Groundwater restrictions

70% restriction for all zones in the Katunga WSPA

Licence holders in the Katunga WSPA were restricted to 70% of their licence volume in 2022-23, the same as the previous year.

Entitlements and use

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

Available water and use

The table below shows the total water available and used under entitlements, and estimated domestic and stock use in 2022-23. 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 WSPA, 2 ML usage per bore per year is assumed.

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

Entitlement volume did not exceed the PCV

The volume of entitlements (60,201 ML) in Katunga WSPA did not exceed the PCV (60,577 ML).

Total volume extracted under licences was within the available volume

The total volume extracted under licences (9,091 ML) was within the volume available for the year (42,140 ML).

Groundwater management unit		PCV	Licensed entitlement (ML)	Water available under licences (ML)	Water taken under licences (ML)
Katunga WSPA		60,577	60,201	42,140	9,091
