The U.S. Army Corps of Engineers has issued an advisory for a harmful algal bloom Status at Blue Marsh Lake.
The announcement Wednesday, which updates the previous “watch status,” is due to the presence of moderate levels of cyanobacteria, also known as blue-green algae, in the lake and the potential for harmful toxins to be present.
Visitors are advised to be alert for harmful algal bloom signs and symptoms, such as extremely discolored water, and to avoid contact with discolored water or scum.
Weekly testing of the swim beach so far has not the presence of toxins so the area remains open for use.
However, officials said, those conditions can change rapidly and visitors should always check water conditions for the signs and symptoms of a harmful algal bloom before recreating.
To protect yourself, your family, and your pets from blue-green algae blooms:
• Avoid water contact in areas where the water is discolored or where you see foam, scum, or mats of algae on the water’s surface.
• Children and pets are especially susceptible to the harmful effects of the toxins produced by blue-green algae. Do not allow children or pets to play in or drink scummy water.
• If you have contact with water that might contain harmful cyanobacteria, rinse off with fresh water as soon as possible afterwards.
