Scientists are working to identify a cyanobacteria bloom near the Maumee River. It's a yearly event that occurs during the warm summer months.
Researchers at the Great Lakes Environmental Research Laboratory confirmed that the cyanobacteria bloom has been intensifying over the last week.
Also known as blue-green algae, it can be harmful to the aquatic environment and to people. People shouldn't swim in a bloom- it can cause skin rashes or even severe stomach problems.
