The City of Muskegon was notified on 8/6/24 by Muskegon County Public Health to post warnings for Harmful Algal Blooms on Muskegon Lake. Read the communication from the county here.

In summary, in early July, the county took samples ​from an algae bloom on Muskegon Lake. The state lab in Lansing tested the sample and determined it to be harmful. A lot of time has passed since that bloom was sampled. However, GVSU has done additional testing on Muskegon Lake and has found evidence of a continuing bloom in some areas. ​The warning signs are just that, a warning to look for algae blooms. They do not confirm the presence of a Harmful Algae Bloom in all the locations where the signs are posted, but it does advise those entering Muskegon Lake to be cautious and take steps to reduce potential exposure to themselves, their families, and their pets.View the Harmful Algae Bloom posters that are posted at beaches here.
