About the area

  • The Stratford Groundwater Management Area (GMA) covers a deep confined sand aquifer with silt, clays and coals extending from Darlimurla to Kalimna, where it partially underlies the Wa De Lock GMA, and fully underlies the Denison GMA, Sale WSPA and Rosedale GMA.
  • The water authority responsible for managing groundwater in the Stratford GMA is Southern Rural Water.
  • The Stratford GMA Local Management Plan details two management zones, where it applies to groundwater resources for all formations below 150 m from the surface in zone 1 and below 350 m from the surface in zone 2.
  • More information on groundwater management can be found on the Southern Rural WaterExternal Link website.

Groundwater restrictions

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

Entitlements and use

Groundwater entitlements have been issued for licensed (non-urban) use and power generation use in the Stratford 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, 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

Current PCV compliance assessment criteria are not applicable in the Stratford GMA. The coal mine licences are in the Stratford GMA physical areas, but the licence volume and extraction are not assigned to or assessed against the GMA.

Total volume extracted under licences was within the available volume

The total volume extracted under licences (19,238 ML) was within the volume available for the year (20,452 ML).
