Wilyabrup Brook
Basin : Busselton Coast
Catchment : Wilyabrup Brook
The condition of the Wilyabrup Brook site (site code: WILY-01), in the lower catchment of Wilyabrup Brook, was assessed between 26 and 27 October 2009, over a 100-m length of stream. At this time no previous assessments of river ecology had been reported.
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 and temperature logged over 24h, and electrical conductivity, pH, colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
