“Harmful algal blooms, or HABs, have been on the rise in recent years, and the development of new outreach tools is an important part of making sure the public is informed on what they look like and the hazards associated with them,” said Teresa Seidel, director of EGLE’s Water Resources Division.

The story map highlights the importance of being aware of what HABs are, when and where they occur, why you should care about them, how to prevent and report blooms, and what to do if you suspect there may be one on a waterbody in Michigan.

It includes:

  • HABs’ effects on people, pets and livestock.
  • Information on the new mapping tool that helps Michiganders know where HABs have been reported.
  • Impacts on swimming and boating
  • Impacts on fishing
  • Impact on aquatic ecosystems
  • How to prevent blooms
  • What the State of Michigan is doing about blooms
