Margaret River Estuary
Basin : Busselton Coast
Catchment : Margaret River
The condition of the Margaret River Estuary site (site code: MR1-ESTU1), was assessed between 10 and 11 February 2016, 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, aquatic habitat, water quality (dissolved oxygen, temperature, electrical conductivity, and pH logged over 24h, and colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
An online condition summary for this site has not been prepared. Please contact the Departments River Science team for site information, and see below for links to information on some of the species found at the site, and some images taken in 2016.
