Helena River - Whiteman Road

Basin : Swan-Coastal

The condition of the Helena River - Whiteman Road site (site code: SWN10), in the Lower catchment of the Helena River, was assessed between 19 and 20 November 2012, over a 100-m length of stream. The site was also assessed in spring 2007, 2008, 2009 and 2010.

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.
