Cressbrook Dam has been closed to water-based recreation activities until further notice.
Toowoomba Regional Council Water and Waste portfolio leader Cr Bill Cahill said Council officers had detected an outbreak of cyano bacteria (blue green algae).
Cr Cahill said the test results meant Council had closed the facility to water-based recreation activities, fishing and boating, as a safety precaution.
“Council will conduct its regular testing regime to determine when the dam can re-open for water-based recreation pursuits,” Cr Cahill said.
“The cyano bacteria represent no risk to drinking water supplies as they are removed by the water treatment and disinfection process.”
