Harvey Main Drain - Johnston Road

Basin : Harvey River

Catchment : Harvey River

The condition of the Harvey Main Drain - Johnston Road site (site code: HR03017), in the lower catchment of the Harvey Main Drain, was assessed between 12 and 13 October 2009, 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, 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.
