Cyanobacteria Bloom in Lake Wiritoa

Cyanobacteria (blue-green algae) at the lake could be a health risk.  Levels of cyanobacteria can change rapidly.  If you see a light green coloured scum forming on the lake avoid contact with the lake water and keep animals out.   The LAWA factsheet on Cyanobacteria will help you know what to look for.’
