Harris River - Downstream Harris Dam 2

Catchment : Collie River

The condition of the Downstream Harris Dam 2 site (CR356HARR1), in the lower Harris River was assessed between 19 and 20 February 2018, over a 100-m length of stream.

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.

The area was also assessed at a site 500m upstream in January 2009 as part of a national assessment of river condition (site code HAR-01 / 6121250) - view report here.
