Harvey River - River Road

The condition of the River Road site (site code: HR140HARV1, site reference: 6134046), in the middle catchment of the Harvey River, was assessed between 7 and 8 February 2018, over a 100-m length of stream. The site was also assessed in February and May 2014 as part of a different project under site HARV11 (site reference: 6131428).

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.
