Moreton Bay Regional Council is urging local residents not to fish or swim in Centenary Lakes at Caboolture.
A council spokesperson said a blue-green algae bloom had been detected at Centenary Lakes with investigations now under way to help pin-point the cause.
“Residents and visitors should continue to enjoy the parklands at Centenary Lakes with confidence, but should avoid coming into contact with the water from the lake at this stage,” the spokesperson said.
“Centenary Lakes is an artificial water system and was never designed for fishing or swimming, although some have continued to use it for those purposes.
"The algae has been treated and is expected to be effective in eradicating the infestation, but as a precaution council is advising people to stay out of the water and avoid coming into contact with fish from the lake until the bloom has completely cleared and the cause of the outbreak is known.”
The spokesperson said signage would be erected at Centenary Lakes advising it was unsuitable for swimming and fishing.
