Algal warning no longer in bloom
A WARNING for people to be careful in Shoalwater Bay has been withdrawn.
The City of Rockingham issued a warning for people to avoid contact with an algal bloom in the bay on April 12.
The algal bloom was located along the shoreline in a 100m stretch of water within Shoalwater Bay near Boundary Road.
It has since dispersed and the warning signs have been removed.
There is no current warning in place.
The algal bloom (trichodesmium erythraeum), commonly referred to as ‘red tide’ or ‘sea sawdust’, can be identified by a yellowbrown surface scum with the appearance of an oil slick.
When it decomposes it may release a pinkish colour into the surrounding water and then may take on a pale green colour.
Contact with the bloom could result in skin irritation and a rash may develop.
Mayor Barry Sammels said this type of algal bloom was naturally occurring and could be transported by wind and tide and potentially impact other beach areas.
