Swimming in the Derwent
Water samples are tested for enterococci, a faecal indicator bacteria used to assess the health risks associated with pathogens in recreational waters. Weekly water quality results will be available throughout the summer on the Derwent Estuary Program website and via Facebook.
All the monitored sites, including Fitzgerald Park at New Norfolk, are classified based on the latest monitoring results in accordance with the Recreational Water Quality Guidelines for Tasmania. Most urban areas experience poor water quality after heavy rain, including those sites rated as "good". Swimming is not recommended in the Derwent for several days after a heavy rain, and never in the vicinity of stormwater drains or urban rivulets.
