Big Brook - Downstream of Big Brook Dam
Basin : Warren River
Catchment : Warren River
The condition of the Downstream of Big Brook Dam site (site code: WR110BIGB1), in the middle catchment of the Warren River, was assessed between 22 and 23 February 2017, 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.
