Drakes Brook - Downstream of Dam Wall

Basin : Harvey River

Catchment : Harvey River

The condition of the Drakes Brook - Downstream of Dam Wall  site (site code: DRAKES01), just downstream of Drakes Brook Dam was assessed on 16 and 17 February 2011. 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 fish and crayfish, aquatic habitat, water quality (dissolved oxygen, temperature logged over 24h and spot readings of electrical conductivity and pH ), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
