Harris River - Downstream Harris Dam 1

Basin : Collie River

Catchment : Collie River

The condition of the Downstream Harris Dam 1 site (site code: HAR-01), in the lower catchment of the Harris River, was assessed between 15 and 16 January 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.

Note:  A new site has been established 500m downstream of HAR-01 called Downstream Harris Dam (CR356HARR1 / 6124028).
