- Now that it feels like summer again, we can get back into the lakes. But you need to watch out for Blue-Green Algae. Blue-Green Algae are natural to Wisconsin lakes, streams and ponds. But summer can cause the amount of algae to grow dramatically. It can be toxic when people or pets ingest it. In extreme cases it causes neurological and liver problems. When Blue-Green Algae increases it looks like pea-soup on the water's surface. If you get sick from it you'll have a rash, upset stomach, breathing trouble and eye irritation. The Wisconsin Department of Health Services wants people to stay out of water that looks like it has the algae, and to report it to them if it makes you sick.For more information please see the link below.
