🚨IMPORTANT NOTICE🚨
Harmful Algal Blooms (Cyanobacteria) have been found in various lakes and bodies of water in Wyoming.
Harmful cyanobacterial blooms, also called harmful algal blooms, are caused by cyanobacteria, also called blue-green algae, that quickly multiply in some water sources. Some, but not all, blooms may become visible and can look like foam, scum, or mats. The blooms can be blue, bright green, brown, or red. Sometimes the blooms can look like paint floating on the water’s surface.
HCBs can make toxins, called cyanotoxins, which can make people, their pets, and other animals sick. People or animals that have direct contact with the contaminated water by swimming, breathing in aerosols, or swallowing the contaminyated water can experience symptoms. These symptoms can vary depending on how they were exposed, how long they were exposed, and the particular toxin involved.
