The Iron County Health Department has issued a health advisory for all of the Gile Flowage due to blue-green algae blooms.
Reports have come in of algae blooms forming throughout Gile Flowage in Iron County, particularly along the north shore near Gile Park and Boat Landing.
Some species of blue-green algae can produce toxins that may cause illness in both humans and animals.
Iron County Health Department staff are working with the Wisconsin DNR to assess water conditions and post health advisory signage at the beach and other public access points.
Health risks from blue-green algal blooms occur when certain types of algae grow rapidly in warm, nutrient-rich, and stagnant water.
Exposure can happen through ingesting contaminated water, inhaling droplets, or direct skin contact with algae or surface scum.
Symptoms in humans may include:
- Nausea, vomiting, and diarrhea
- Abdominal cramps
- Respiratory irritation or wheezing
- Eye irritation
- Skin rashes, hives, or blisters
Symptoms in pets and wildlife may include:
- Vomiting or diarrhea
- Weakness or difficulty walking
- Seizures
- Loss of appetite
- Sudden death in severe cases
Symptoms typically appear within minutes to hours after exposure.
When to Avoid Water Contact You should avoid swimming, wading, or letting pets enter water that:
- Looks like pea soup or spilled pain
- Has a strong green discoloration or streaks
- Shows surface scums, mats, or foamy films
- Contains green dots or globs floating under the surface
If you or your pets experience symptoms that could be related to blue-green algae exposure, please contact your healthcare provider or veterinarian.
