Blue-green algae bloom confirmed at Harrington Park Lake

A blue-green algae bloom has been confirmed at Harrington Park Lake.

Monitoring undertaken by Council has identified the presence of a toxic species of algae at levels that present a health risk associated with contact with the water. Residents are advised human and animal contact with the water should be avoided, including drinking, fishing, swimming, boating and allowing pets to enter the water. Inhalation of air affected by blue-green algae for an extended period may cause respiratory distress.

Algae is a natural part of the aquatic ecosystem with most species safe or non-toxic. However, blue-green algae produce toxins that can be damaging to humans, domestic animals and livestock that come in contact with the water. People who believe they may have been affected by blue-green algae are advised to seek medical advice. 

In normal conditions, the blue-green algae exist in low numbers and are a part of a healthy ecosystem. However, under certain conditions, the algae can grow rapidly, producing an algal bloom. Recent weather conditions, including high levels of sunlight, warm water temperatures and a lack of rainfall, have contributed to the bloom.

Signage has been erected at locations around Harrington Park Lake to advise visitors to avoid contact with the water.

It is not possible to predict how long the algae will remain at high levels. Council will continue weekly monitoring of the water quality at Harrington Park Lake and signage will remain in place until blue-green algae levels have reduced to a save level.
