Algal bloom in Lake Ohakuri
A potentially toxic blue-green algal bloom has been detected in Lake Ohakuri, the largest lake in the Waikato River hydro system.
Environment Waikato tests of the lake, midway between Kinleith and Wairakei, show a volume of blue-green algae cells of 3.2 cubic millilitres per litre of water, above the recreation health guidelines of 1.8 cubic millilitres per litre. No health warnings have been issued for the lake but toxins from the algae can affect the health of humans and animals.
This is the first bloom in the Waikato River for several years.
