The National Capital Authority have let it be known that Lake Burley Griffin is so bad they’ve had to turn off the water jet for fear of spreading the poison:
Lake Burley Griffin is closed to activities that involve whole-body water contact or submersion of the head due to extreme levels of blue-green algae.
National Capital Authority chief executive, Gary Rake said there has been a significant spike in blue-green algae levels over the last week.
“Water quality results received today indicate blue-green algae levels are more than 1000 times higher than the level considered safe for activities such as swimming,” he said.

Extreme levels of the blue-green algae strain, Anabaena circinalis have been recently detected.
“More worryingly, this is a very different strain of blue-green algae from the one we typically experience over the summer months. Lake users who engaged in secondary contact activities over summer need to carefully reassess the risks.”
The Captain Cook Memorial Jet in Central Basin will remain 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.
