Wimmera's Water Resources
Groundwater resources in the Wimmera are part of the larger Wimmera-Mallee stock and domestic supply system, which is thought to be the largest water supply system of its kind in the world. The Wimmera-Avon Basin region has large reserves of groundwater with varying salinity levels. Good quality groundwater is found in the far west of the Basin. Elsewhere, the groundwater is generally of poor quality, and therefore, it is of limited use.
