The Community and Public Health division of the Canterbury District Health Board has lifted its algal bloom health warning issued for Te Roto o Wairewa/Lake Forsyth on 18 January 2017.
Recent water testing at Te Roto o Wairewa/Lake Forsyth has shown the quantity of potentially toxic blue-green algae (Anabaena) in the lake has decreased and concentrations are now below the levels that are of concern to public health.
Dr Alistair Humphrey, Canterbury Medical Officer of Health, says Environment Canterbury's sampling of Te Roto o Wairewa/Lake Forsyth will continue to be monitored on a monthly basis and the public will be notified if there is a risk to public health again.
