About the area
- The Rosedale Groundwater Management Area (GMA) covers a confined sand aquifer with silt, clays and coals in the Central Gippsland catchment, where it partially underlies the Wa De Lock GMA and Sale WSPA, fully underlies the Denison GMA, and fully overlies the Stratford GMA.
- The water authority responsible for managing groundwater in the Rosedale GMA is Southern Rural Water.
- The Rosedale GMA Local Management Plan details three management zones, in which the plan applies to groundwater resources for all formations at various depths:
- between 50 m to 150 m below the surface in zone 1,
- 25 m to 350 m below the surface in zone 2, and
- 200 m to 300 m below the surface in zone 3.
- More information on groundwater management can be found on the Southern Rural website.

Groundwater restrictions
There were no restrictions on licensed use for the Rosedale GMA in 2021-22.
Entitlements and use
Groundwater entitlements have been issued for licensed (non-urban) use and power generation use in the Rosedale GMA. Groundwater is also available for domestic and stock use.
Entitlement volumes

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 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 (22,272 ML) in the Rosedale GMA did not exceed the PCV (22,372 ML).
Total volume extracted under licences was within the available volume
The total volume extracted under licences (8,106 ML) was within the volume available for the year (18,441 ML).
