Watch out for blue green algae in your lakes

It’s July and everyone is thinking that swimming in a lake may be a great way to escape the heat, but there’s another danger that could be lurking – blue green algae. This toxic algae, which can be harmful to people and pets, loves hot, calm weather.

To help local governments address the potential presence of harmful algae blooms (HABS) in local bodies of water, the Minnesota Pollution Control Agency (MPCA) has developed several resources that you can consult. The MPCA Water Recreation Advisories website explains that sharing information about the risks with beach users can be an important first step. The site provides resources, such as posters, to help spread the word. The site also describes simple steps that local governments can take to monitor for HABs.

The MPCA also shared a news release that your city or county can adapt and share on your website or newsletters as well as general information on HABs, including facts sheets in several languages.

If you have any questions or would like further assistance, please contact Cathy Malakowsky at the MPCA at or 507-383-5949.
