A harmful algal bloom has been identified at Hauser Lake near the Clark’s Bay Day Use Area. Sampling performed by Lewis and Clark Public Health on Wednesday (8/10), indicated the presence of blue-green algae species producing microcystin toxin well above the state of Montana’s warning limit.
In addition, sampling at the Lake Helena Boat Launch on Lincoln Rd E, the Causeway Boat Launch, and Canyon Ferry Lake at Hellgate Campground on Wednesday also indicated the presence of blue-green algae. These sites tested negative for toxins. Users of these areas should still be cautious as conditions may rapidly change.
Suspect a HAB? When in doubt, stay out. Avoid exposure to any water that may contain harmful algae. Be especially vigilant with children, pets, and livestock. Direct contact, ingestion, or inhalation of cyanotoxins may irritate the skin, eyes, nose, and respiratory system or cause nausea, vomiting, diarrhea, or headaches. If you suspect a HAB-related illness in a person or animal, call Poison Control at 1-800-222-1222 and seek medical attention.
