The National Centers for Coastal Ocean Science reports cyanobacteria bloom in western Lake Erie has an approximate area of 180 square miles, which is an increase in area since July 1.
The Microcystis bloom extends from Maumee Bay north to Stony Point, Michigan and to the south just east of Maumee Bay State Park.
Sandusky Bay has a local bloom of mixed cyanobacteria.
Toxins have been detected below the recreational limit. They can be highly concentrated in scums. If you see scum, keep your pets and yourself out of the water. In the satellite imagery or bloom forecast position products, any areas that are orange or red are likely to have scum, especially during calm winds
