Vasse River - Upper Vasse River

Basin : Busselton Coast

Catchment : Vasse - Ludlow rivers

The condition of the Upper Vasse River site (VR94VASS1) was assessed between 11 and 12 October 2017, over a 100-m length of stream. This site is situated in the lower catchment of the Vasse River.

The assessment was conducted using standard methods from the South West Index of River Condition. Measures chosen for this assessment included fish and crayfish, macroinvertebrates, aquatic habitat, water quality (dissolved oxygen, temperature, electrical conductivity, and pH logged every 30 minutes between 11 October 2017 and 11 March 2018 and colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
