Blue green algae Red Alert warning lifted – Yanga Lake

Blue green algae Red Alert warning lifted – Yanga Lake

08 June 2022

WaterNSW has issued a Red Alert (High Alert) advisory for high levels of potentially toxic blue-green algae for Quipolly Dam. Quipolly Dam is located approximately 10km North East of Quirindi.

This red alert warning applies only to untreated water at the above location and will remain in place until monitoring and test results confirm that the risk is sufficiently diminished. People should avoid consuming untreated water from this waterbody and prevent pets and livestock from drinking this water.

People should avoid recreational activities such as swimming, water skiing, canoeing and any other activity that brings them into contact with this waterbody until the red alert warning is lifted.

Potentially toxic blue-green algae may cause gastroenteritis if consumed, while contact can cause skin and eye irritations. Consumption of water containing algal toxins may cause liver damage and other health problems. Boiling the water does not remove algal toxins.

People who suspect they have been affected by blue-green algae should seek medical advice.

People should not eat mussels or crayfish from red alert warning areas. A precautionary approach to eating fin fish from red alert warning areas is advised. Any fish caught should be cleaned and washed thoroughly in uncontaminated water; the internal organs should not be eaten.  Avoiding fishing during a bloom is the best way to minimise risk.

Blue-green algae is naturally occurring and can reproduce quickly in still or slow-flowing water when there is abundant sunlight and sufficient nutrients.
