The Community and Public Health division of the Canterbury District Health Board has lifted its algal bloom health warning issued for Te Wairewa / Lake Forsyth on 25 November 2016.
Recent water testing at Te Wairewa / Lake Forsyth has shown the quantity of potentially toxic blue-green algae (Anabaena and Nodularia) in the lake has decreased and concentrations are now below the levels of concern to public health.
Dr Alistair Humphrey, Canterbury Medical Officer of Health, says Environment Canterbury's sampling of Te Wairewa / Lake Forsyth will continue on a fortnightly basis over the summer months and the public will be notified if there is a risk to public health again.
