The Microcystis cyanobacteria bloom in western Lake Erie has an approximate area of 540 square miles, which is an increase in area since Sept. 2.
The bloom extends from Stony Point, north of Monroe, Michigan, to Huron, Ohio and further out into the lake to the Bass Islands and Kelleys Island.
Cyanobacteria is detected in parts of Sandusky Bay, unrelated to western Lake Erie blooms. The past few days of imagery can be seen at the HAB monitoring site.
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.
