- Cyanobacteria, also known as blue-green algae, can form harmful blooms in Wyoming waters.
- Blooms may appear in various colors and forms, posing risks to human and animal health.
- State agencies urge the public to report suspected blooms and related illnesses.
July 2, 2024 — As summer heats up and visitors head to Wyoming’s lakes and reservoirs, state agencies are warning about the potential dangers of harmful cyanobacterial blooms (HCBs). These blooms, caused by blue-green algae, can produce toxins and irritants that threaten human and animal well-being.
HCBs typically emerge in mid to late summer, affecting both flowing and stagnant waters. While they can manifest in various colors like green, tan, brown, or blue-green, their appearance may range from spilled paint or grass clippings to clumps, scums, films, mats, or gelatinous balls.
What to do around harmful algae blooms.
If a bloom is suspected, the Wyoming Department of Health (WDH) and Wyoming Livestock Board (WLB) recommend taking precautions:
- Avoid contact with water near the bloom, especially in dense areas.
- Refrain from ingesting water from the bloom, as boiling or filtering won’t eliminate toxins.
- Rinse fish with clean water and consume only the fillet portion.
- Avoid water spray from the bloom.
- Prevent pets and livestock from drinking water near the bloom or consuming bloom material.
- If contact occurs, rinse with clean water promptly and seek medical attention if adverse health effects arise.
