Harmful algal bloom confirmed on Hess Lake

BROOKS TOWNSHIP, Mich. (WOOD) — The Michigan District Health Department No. 10 has confirmed that a harmful algal bloom has been found in Newaygo County’s Hess Lake.

The bloom was first reported on June 26. Samples collected by DHD#10 were sent for testing to the Michigan Department of Health & Human Services, which confirmed the findings.

“Not all algal blooms are harmful, but the results from this particular bloom have classified it as harmful,” Meghan Stih, the Environmental Health Supervisor for DHD#10, said in a social media post . “Harmful algae bloom toxins can be hazardous to aquatic life, pets and humans, so it is very important to avoid areas where these blooms have been identified.”

The agency will post signs around the boat launch on Hess Lake to notify visitors to avoid contact with the water.

Algal blooms typically occur in the summer when warm temperatures and sunshine combine with nutrients in the water to feed the algae. Blooms can last for several days and sometimes even months. The water will look “scummy” or like “spilled paint or pea soup.”

If a person has contact or swallows water containing cyanotoxins , they may experience a variety of symptoms, including stomach pain, diarrhea, vomiting, weakness, headaches, dizziness and difficulty breathing.

Pets can also react to toxins and typically show symptoms before humans. If your pet has had contact with contaminated water and shows similar symptoms along with excessive drooling or staggered walking, residents are encouraged to contact a local veterinarian.

If you or a pet have been exposed to a harmful algal bloom, experts recommend you shower or bathe immediately. You should also reach out to your local medical provider or poison control .
