The Barry-Eaton District Health Department (BEDHD) is advising residents and visitors to use caution after a harmful algal bloom was found at Gun Lake.

Harmful algal blooms happen when blue-green algae grow quickly in lakes and ponds. You cannot tell if a bloom is harmful just by looking at it, so it is best to avoid any water that has visible algae.

Do not swim, wade, water ski, or play in water that is discolored or has algae floating on the surface. Harmful algal blooms can make the water look bright green, blue-green, brown, or red. It may also look like spilled green paint, pea soup, or have thick mats of algae on the surface.

Pets are at greater risk because they may drink lake water or lick algae off their fur after swimming. Keep pets away from water with algae, and do not let them drink lake water. If your pet gets into the water, rinse them off with clean water right away. Contact your veterinarian if they become sick.

 

People can be exposed to harmful algae by touching the water, swallowing it, or breathing in water spray during activities like swimming or boating.

 

Symptoms may include:
Skin rash or irritation
Red or irritated eyes
Irritated nose or throat
Stomach pain
Nausea, vomiting, or diarrhea
Headache
Fever
Coughing or trouble breathing after breathing in water spray
Symptoms can start within a few hours or up to a few days after exposure.

 

If you or your child come into contact with water that may have a harmful algal bloom:
Rinse off right away with clean, fresh water.
Wash swimsuits and towels before using them again.
Watch for symptoms over the next few days.
If you become sick, contact your healthcare provider.

 

BEDHD will continue to monitor conditions in coordination with state partners and provide follow-up information as needed or until the harmful algal bloom has resolved.
