Bickley Brook - Eva Street Upstream

Basin : Swan-Coastal

Catchment : Canning River

The condition of the Bickley Brook - Eva St Upstream site (site code: BICKBKEUS), in the upper catchment of  Bickley Brook was assessed between 13 and 14 October 2016, over a 100-m length of stream. The site was also assessed in spring 2011, 2012 and autumn 2011 and 2013.

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 over 24h, and colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
