Basin : Donnelly River
Catchment : Donnelly River
The condition of the Yanmah Brook site (site code: DR199MANJ1), in the middle catchment of Manjimup Brook, was assessed between 8 and 9 February 2017, 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 water quality (dissolved oxygen, temperature, electrical conductivity, and pH logged every 30 minutes from 6 December 2016 to 31 January 2017), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
An online condition summary for this site has not been prepared. Please contact the Departments River Science team for site information, and see below for some images taken in 2017.
Fish and crayfish
The site could not be sampled for fish and crayfish as it was too shallow.
