Yanmah Brook

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.
