Collie River - Wellington Dam Wall

Basin : Collie River

Catchment : Collie River

The condition of the Wellington Dam Wall site (CR169COLL1), in the lower Collie River was assessed between 28 February and 1 March 2018  and 7 and 8 March 2017,  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 site was also assessed in January 2009 as part of a national assessment of river condition (site code CR-08 / 6121242) - view report here.
