Groundwater restrictions

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

Entitlements and use

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

Entitlement volumes

Use type	2021-22 (ML)	2020-21 (ML)
Ballarat urban ¹	3,000	3,000
Licensed use (non-urban)	889	889
Total	3,889	3,889

Use type	2021-22 (ML)	2020-21 (ML)
Ballarat urban ¹	3,000	3,000
Licensed use (non-urban)	889	889
Total	3,889	3,889

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, 1.5 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 groundwater 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

The volume of entitlements (3,889 ML) in the Cardigan GMA did not exceed the PCV (3,967 ML).

Total volume extracted under licences was within the available volume

The total volume extracted under licences (674 ML) was within the volume available for the year (3,889 ML).
