Health warnings have been issued for both Lake Okaro and Lake Rotoehu because of the presence of blooms of potentially toxic blue-green algae.
Contact with water affected by blooms of blue-green algae can cause asthma and hayfever attacks in some individuals. Contact with the blue-green algae can also cause skin rashes, stomach upsets, and in some cases neurological effects such as tingling around the mouth, headaches, breathing difficulties and visual problems.
“The health warnings mean that people should avoid any activity which involves contact with the water in Lake Okaro or Lake Rotoehu,” says Dr Neil de Wet, Medical Officer of Health for Toi Te Ora Public Health. It is advisable not to paddle, wade, swim, or participate in any recreational activity that might involve any direct contact with the lake water.
Algae may also accumulate and form scum collections along the shoreline of the lakes. It is especially important that parents ensure that children avoid contact with both the water and any algal scum along the shoreline as this may be toxic.
It is also advisable to keep pets and livestock out of the water and off the shoreline.
Signage will be erected at both Lake Okaro and Lake Rotoehu advising potential lake users about the algal blooms.
The Rotorua Te Arawa Lakes Programme partner Bay of Plenty Regional Council takes water samples from 13 key locations across the Rotorua lakes each year to check for blue-green algae while working to improve the water quality of the Te Arawa Lakes. These monitoring sites include Lakes Ōkaro, Rotoehu, Rotorua, Rotoiti and Tarawera. For more information head to www.rotorualakes.co.nz

Bay of Plenty Regional Council has commenced region wide maritime patrols – reinforcing safety on the water.
Bay of Plenty Regional Council Harbourmaster Peter Buell said last year nine people died in Bay of Plenty waters and 19 nationwide.
“Nearly half of 2017’s boat-related deaths occurred in the Bay of Plenty – most could have been prevented if a proper fitting lifejacket had been worn.”
Harbourmaster Buell says the first patrols for 2018 went out over labour weekend and issued a high amount of bylaw breaches.
“This year’s 100 per cent increase in breaches, compared with 2017 Labour Weekend is disappointing.
“Patrols issued: eight breaches of bylaw for exceeding five knots; ten for failing to carry enough personal floatation devices; four for unnamed boats or unregistered personal water craft, including Jetski; and three for towing with no observer.”
The volume of breaches should be a reminder for people to be prepared, know the rules and stay safe when heading out on the water, he says.
“2018 is off to a good start with no deaths so far and we’re working hard to keep it that way.”
Harbourmaster Buell wants to reinforce that the patrols don’t want to ruin your day on the water, they’re in place to ensure you and your family stay safe out there.
