HENLEY LAKE CLOSED DUE TO TOXIC ALGAE

Masterton District Council has closed Henley Lake for recreational purposes and issued a health warning after tests show concentrations of cyanobacteria (toxic algae) to be at high levels.

Toxic algae (cyanobacteria) is found in the majority of lakes and rivers in New Zealand. Under certain conditions, including warm temperatures, prolonged periods of sunshine and low water flow through the lake, the algae can proliferate to very high numbers.
