Breera Brook 2

Basin : Swan-Coastal

The condition of the Breera Brook (site code: SR292AELLE2), in the middle catchment of the Beera Brook, was assessed between 27 and 28 February 2019, 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.
