Mats of toxic algal species, including Phormidium, are currently present within Five Mile Bay, Acacia Bay, the main lake front in Taupō, Whakaipo Bay, Hallet's Bay and Kinloch Beach.


People are advised not to paddle, wade, swim, or participate in any recreational activity that might involve any direct contact with the algal mats or swallowing of affected lake water. Parents should ensure young children do not come into contact with algal mats in the water or on the shoreline.


Dogs are especially vulnerable, so people should keep their pets and livestock out of the water and off the shoreline in the known affected areas or where the algae is visible.
