water flowing over stones in a riverCanterbury District Health Board’s Community and Public Health unit has lifted its algal bloom health warning issued along the Waikirikiri/Selwyn River at Chamberlains Ford.

The warning was issued on 16 December 2021.

Recent cyanobacteria surveys of the Waikirikiri/Selwyn River has shown the cover of potentially toxic algae (benthic cyanobacteria) in the river has reduced and it is now below levels that are of concern to public health.

Canterbury Medical Officer of Health Dr Ramon Pink says Environment Canterbury’s monitoring of the Waikirikiri/Selwyn River will continue to the end of this summer.

It will then 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 for Waikirikiri/Selwyn River at Glentunnel.
