Blue-green algae Red Alerts for Angourie Blue and Green Pools in Angourie near Yamba

03 February 2020

A recreational Red Alert level warning (high alert) for blue-green algae has been issued for Angourie Blue and Green Pools in Angourie, south of Yamba. Sampling by Clarence Valley Council has shown high levels of potentially toxic species in both pools.

Warning signs have been installed and Clarence Valley Council have issued alerts via their website and social media. This Red Alert does not affect local drinking water supplies, which remain safe to drink.

A Red Alert level warning indicates that people should not undertake recreational activities where they may come into direct contact with the water, such as swimming or other water-based activities.  People are advised not to enter the water, swim or bathe in water, or drink untreated water while this red alert level warning is in place.

The species of blue-green algae identified is potentially toxic and may cause gastroenteritis in humans if consumed, and skin and eye irritations after contact. Blue-green algal toxins can also affect pets and owners are advised to restrict pets from accessing waterways that have a Red Alert level warning in place.

People should not eat mussels or crayfish from red alert warning areas. It is advised not to fish from Red Alert level warning areas. If any fish are caught, they should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of appropriately (these may contain toxins).

Blue-green algae usually appear as green paint-like scums on the water, near the edges, or as greenish clumps throughout the water. It makes the water appear dirty, green or discoloured and generally has a strong musty or earthy odour.

Blue-green algae occur naturally and can reproduce quickly in favourable conditions where there is still or slow-flowing water, abundant sunlight and sufficient levels of nutrients.

It is not possible to predict how long the algae will remain at high levels. Regular monitoring by Clarence Valley Council will continue, and the alert will be lifted as soon as the high levels of algae dissipate.

People who believe they may have been affected by blue-green algae are advised to seek medical advice.
