The National Capital Authority has announced they’ve shut large sections of the lake and the Captain Cook Memorial Jet.
The following areas of Lake Burley Griffin are currently closed to primary contact recreation (swimming, diving and windsurfing):
— West Basin (extreme blue-green algae alert)
— Black Mountain Beach (extreme blue-green algae alert)
— Yarramundi Reach / Weston Park West (extreme blue-green algae alert)
— Tarcoola Reach / Weston Park East (high blue-green algae alert)
— East Basin (high blue-green algae alert)
— Lotus Bay (high bacterial alert)
The Captain Cook Memorial Jet in Central Basin will also be turned off as winds can create fine mists and cause jet water to travel to areas around the lake, potentially exposing the public to algae either through direct contact with, or inhalation of, the mist.
The water is closed to primary contact recreation as exposure to this level of blue-green algae, or bacteria carries an increased risk of adverse health effects.
Secondary contact (rowing, fishing, boating and canoeing) is still allowed, showering after leaving the water is recommended.
