Blue-green Algae Red Alert Issued for Lake Ainsworth

15 FEBRUARY 2023

A Red Alert level warning for high levels of potentially toxic blue-green algae has been issued for Lake Ainsworth in the North Coast region by Ballina Shire Council.

This Red Alert warning will remain in place until monitoring and test results confirm that the risk is sufficiently diminished.

People should avoid recreational activities such as swimming, 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.

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

People should not eat crayfish from Red Alert warning areas. A precautionary approach to eating 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.

Visit the local council or local water utility websites for information about the management of blue-green algae risks in the nearby treated drinking water supplies.
