Wimmera region

Our catchment

Our vision is for a healthy Wimmera catchment where a resilient landscape supports a sustainable and profitable community

The Wimmera region covers approximately 10% of Victoria and is the fifth largest catchment management region in Victoria, encompassing 2.3 million hectares.

The Regional Catchment Strategy (RCS) is the overarching strategy for integrated catchment management (ICM) in the Wimmera. It provides detailed information for our region. You can read it online.

Our connected systems

Wimmera’s natural resources are the building blocks of healthy and resilient environments and the focus of integrated catchment management.

Healthy and resilient environments rely on people working together to coordinate planning, investment and on-ground activities in an efficient and effective way to achieve a range of environmental, social, economic and cultural outcomes.


Rivers and streams, wetlands and groundwater all play an important part in providing economic, social, cultural and environmental benefits to the region.

The Wimmera contains 25% of Victoria’s wetlands.
