Water Quality update – Extreme levels of blue green algae detected

The National Capital Authority (NCA) wishes to advise that, until further notice, the following areas of Lake Burley Griffin are closed to primary contact due to Extreme levels of blue green algae. 

East Basin – CLOSED TO PRIMARY CONTACT 

Central Basin - CLOSED TO PRIMARY CONTACT 

Primary contact recreation includes activities which involve full immersion such as swimming, bathing, novice secondary contact recreation, or activities which pose a greater risk of swallowing water or having the face wet by spray (e.g windsurfing).  

These activities are not permitted at sites closed to primary contact. 

Persons engaged in secondary contact recreation activities, such as canoeing and rowing, in these areas should be careful to limit any water exposure and should shower immediately after contact with the water. 

All other recreational areas are open to both primary and secondary contact. 

Pet owners should not allow their animals to swim in or drink Lake water in areas where there are algal scums. 

The NCA will continue to monitor lake water quality and provide updates when available. For up to date Lake Burley Griffin water quality information, restrictions, alerts and health warnings visit http://www.theswimguide.org/
