DEECA Victorian Water Accounts 2021-22

About the area

The Denison Groundwater Management Area (GMA) covers a shallow sand aquifer with silts and clays and is bordered to the north by the Thomson River, where it partially overlies the Sale WSPA and fully overlies the Rosedale GMA and Stratford GMA.
The water authority responsible for managing groundwater in the Denison GMA is Southern Rural Water.
The Central Gippsland Shallow Aquifers Local Management Plan incorporates the Denison GMA, where it applies to groundwater resources for all formations between the surface to 25 m below the surface.
More information on groundwater management can be found on the Southern Rural Water website.

Groundwater level trends

There are insufficient state observation bores in the Denison GMA to adequately define the groundwater resource or changes to the resource over time.

Groundwater restrictions

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

Entitlements and use

Groundwater is available for licensed (non-urban) supply, salinity control extraction and for domestic and stock use.

Entitlement volumes

Use type	2021-22 (ML)	2020-21 (ML)
Licensed use (non-urban) ¹	18,499	18,499
Total	18,499	18,499

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

Entitlement volume did not exceed the PCV

The volume of entitlements (18,499 ML) in the Denison GMA did not exceed the PCV (18,502 ML).

Total volume extracted under licences was within the available volume

The total volume extracted under licences (2,166 ML) was within the volume available for the year (19,020 ML).

Groundwater management unit		PCV	Licensed entitlement (ML)	Water available under licences (ML)	Water taken under licences (ML)
