Lake Awoonga blue green algae at high level
BLUE-green algae in Lake Awoonga is now at a high alert level.
Gladstone Area Water Board chief executive Jim Grayson said the recreational hazard alert had been upgraded to high and was expected to remain at that level throughout spring and summer.
He said the increase in blue-green algae cells usually occurred in late October or early November, and was a natural phenomenon in many Australian waterways, especially in tropical and sub-tropical regions.
"The treatment process used by the Gladstone Area Water Board is designed to efficiently remove algae cells to produce safe drinking water," Mr Grayson said.
"This process is constantly monitored to ensure confidence in the provision of high quality drinking water to the Gladstone community."
However, people coming into direct contact with raw water in Lake Awoonga should be aware that blue-green algae may cause skin and eye irritation.
Drinking untreated or boiled water may result in illness.
Anglers are reminded that glue-green algae toxins can accumulate in the internal organs of fish and in mussels.
