Update: Lake Burley Griffin remains closed to primary contact due to elevated blue green algae levels

Media Release
23 March 2018

The National Capital Authority (NCA) wishes to advise the community and Lake Burley Griffin (the Lake) recreational users that due to elevated blue green algae levels, the Lake remains closed to primary contact. This includes full immersion activities such as swimming.

Some areas have been closed to primary contact since 22 February. The analysis of water quality samples taken on Monday 19 March confirms that algae levels have remained elevated and are not safe for primary contact recreational activities. All Lake users should look for algae warnings signs indicating the current alert level at major water entry points.

The Lake will remain closed to primary contact until algae levels have reduced to safe levels. Only experienced lake users can participate in secondary contact recreation activities, such as sailing, canoeing and rowing.

There is an increased risk of adverse health affects from water exposure. If contact occurs, wash the skin as soon as possible with water and soap. Symptoms of exposure may include skin irritation, flu-like symptoms, and gastrointestinal illness. It is advised to see a healthcare professional if these symptoms occur.

Event organisers should ensure that participants are aware of the algae alert level, associated exposure risks and provide adequate showering facilities for after events.

The NCA will continue to monitor lake water quality as per standard protocols with samples collected weekly. Under the ACT Guidelines for Recreational Water Quality, two consecutive clear results must be received before lowering or removing alerts.

While algae levels are elevated in Central Basin, the Captain Cook Memorial Jet will not be operating to remove the risk of inhalation of water droplets from the spray.
