Green Lake has been closed to recreational use after potentially toxic blue-green algae was observed this week.
Samples of water from the lake have been taken for laboratory testing to confirm the species of algae.
In the meantime, people who come into contact with this water should wash affected skin immediately in clean water.
People are also advised not to use the affected water for cooking, drinking, washing or showering. Boiling the affected water will not make it safe to use.
