Soils

Soils range from silty loam on the higher undulating country to self mulching grey clays soils on the seasonally inundated floodplains. Gilgai’s are also common on the lower floodplains around Lake Cowal. The soils are generally very low in organic carbon, are highly compacted and often lack ground cover due to overgrazing and cultivation. Soil erosion and soil structure decline are prevalent over extensive areas of the catchment.
