Shannon River - Nelson Road
Basin : Shannon river
Catchment : Shannon River
The condition of the Nelson Road site (site code: EVSHA04), in the middle catchment of the Shannon River, was assessed between 16 and 17 November 2009, 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 fish and crayfish, macroinvertebrates, aquatic habitat, water quality (dissolved oxygen and temperature logged over 24h, and electrical conductivity, pH, colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
