The West Wimmera GMA incorporates the area west of the Wimmera River to the South Australian border, and north to the Big Desert.
The area is essentially dependent on groundwater for urban and agricultural water supply, the main resource being the Tertiary Limestone Aquifer. This aquifer - or underground lake - is the primary supply for stock, irrigation and town supplies across the area.

Local Management Plan
In 2011, GWMWater published the West Wimmera Groundwater Management Strategy. This Strategy was devised to ensure that the precious groundwater water resources in the region are managed with the goal of long-term sustainability. The management arrangements set out in the Strategy have been further refined and simplified in the 2019 West Wimmera GMA Local Management Plan.

Trading rulesThe West Wimmera area is managed by rules according to the West Wimmera Groundwater Management Strategy.
Restrictions on issuing TWEs and groundwater licences: GWMWater won't approve a TWE or groundwater licence if it: a) exceeds the PCV for a zone; b) exceeds the Permissible Annual Volume (PAV) for a Border Zone; c) poses an unacceptable risk to surrounding groundwater usesr including the environment. GWMWater also won't approve a TWE or groundwater licence if it results in water being moved into any of the following sub-zones:
Border Groundwaters AgreementAll groundwater resources along the Victorian-South Australian border are also subject to the Border Groundwaters Agreement. This agreement takes precedence over local water licensing authority policies (such as GWMWater's). Find out more about the Border Groundwaters Agreement (external webpage). |
Annual report
Further information...Annual seasonal restriction announcement for season 2020/21 The seasonal restriction for licensed groundwater users in Neuarpur Sub-zone 1 will remain restricted to 80% of their licence volume for the 2020/21 season.

Groundwater is an essential resource for our community, especially in the western parts of the region.
If you're planning to construct or alter a groundwater bore, you need to apply for a licence before you can start works.
Apply for a 'take and use' groundwater licence To use groundwater for irrigation or other commercial purposes, you must have a ‘take and use’ licence. |
The Murrayville Groundwater Management Area (GMA) occupies 1,916 square kms centred on the town of Murrayville, between the Murray Sunset National Park and the Big Desert.
The dominant land use within the GMA is dryland agriculture, however, landholders take advantage of the good quality groundwater and suitable soils to cultivate irrigated crops such as potatoes, cereals and olives.
The area is essentially dependent on groundwater for urban and agricultural water supply, the main resource being the Tertiary Limestone Aquifer. This aquifer - or underground lake - is the primary supply for stock, irrigation and town supplies across the area.

Management Strategy
The Murrayville Local Management Plan (Groundwater) 2017 provides a management strategy for the Tertiary Limestone Aquifer (the Murray Group Limestone). The plan ensures the Aquifer is protected and used so that the community can rely on it for years to come. There's also a focus on educating the community on the importance of good water resource management.
