The Canterbury District Health Board has lifted its algal bloom health warnings for the Selwyn/Waikirikiri River at the Whitecliffs Domain and downstream of the Domain near the picnic area. The warnings were issued on 5 February and 21 January 2020.
Recent cyanobacteria surveys of the Selwyn/Waikirikiri River has shown the cover of potentially toxic algae (benthic cyanobacteria) in the river has decreased and are now below a level that is of concern to public health.
Canterbury District Health Board Medical Officer of Health Dr Cheryl Brunton says Environment Canterbury’s monitoring of the Selwyn River has now finished for the summer season and will resume next summer when there is increased likelihood of cyanobacteria growth. The public should therefore remain vigilant when accessing waterways and exercising dogs along rivers.
A warning remains in place due to ongoing algal blooms at Te Waihora/Lake Ellesmere.
