With the hot weather we are having this week, residents are looking for ways to cool off. Unfortunately multiple lakes within Le Sueur County have received reports of Blue Green Algae Blooms!

Blue Green Algae is caused by nutrient rich warm waters. The heat we are having this summer creates ideal conditions for these blooms to occur!

Below is a list of different recreational activities and their associated exposure risk to Blue Green Algae. While it may be tempting to swim in water when it is this hot out, being exposed to Blue Green Algae toxins can make people sick and can be toxic to pets!

We are already getting reports of Blue Green Algae!

According to the Minnesota Pollution Control Agency, "Blue Green Algae is normally present in bodies of water and common in Minnesota. This type of bacteria thrives in warm, nutrient-rich water. When conditions are right, the blue-green algae can grow quickly forming “blooms.” Certain varieties of blue-green algae can produce toxins."

If you see blue-green algae in the water, please do not allow people or pets to swim in it! People can become very sick from these blooms. Symptoms include: vomiting, diarrhea, rash, eye irritation, cough, sore throat, and headache. Pets can experience similar symptoms (mentioned above) and in some cases can die from exposure.
