Harvey River - River Road

Basin : Harvey River

Catchment : Harvey River

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 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 February and May 2014 as part of a different project under site HARV11 (site reference: 6131428).

Note: only fish and crayfish are targeted by sampling methods, however where other species were caught and/or observed they are included below.


Species found in subcatchment

This includes all species found within the subcatchment of the assessment site, from this and previous studies in the area. The photos are linked to more information about each species, including maps of where they are expected across the south-west.

Other aquatic fauna

Although not targeted by collection methods the native rakali water rat (Hydromys chrysogaster) was recorded during February 2014 assessments, and Carter’s freshwater mussel (Westralunio carteri) were observed during May 2014 and February 2018 assessments. Notably the mussels were in good abundance at the last assessment in February 2018 with handfuls collected from the riverbed.
