Cyanobacterial monitoring results

The Bay of Plenty Regional Council monitors the Rotorua Te Arawa Lakes for algal blooms. 

We monitor thirteen sites for cyanobacteria, spread across four lakes: Lake Rotorua, Lake Rotoiti, Lake Rotoehu, and Lake Ōkaro (and Lake Tarawera if required). These sites have been selected because they have been known to bloom in the past and the area is regularly used by the public for recreational activities.  

Sites are given an alert level status based on the number of bacteria found. These results help Toi Te Ora to make a decision on whether a health warning should be put in place.
