This alert has been placed by visual observations and satellite imagery. Algae samples will be collected to further the algae situation to further confirm the algae red alert.
Water users on the Macintyre River further upstream and downstream of Inverell should apply a high level of caution and seek alternate water supplies if algae are visually present.
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, 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 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.
People who suspect they have been affected by blue-green algae should seek medical advice.
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.
