The cyanobacteria bloom in western Lake Erie has an approximate area of 140 square miles, which is a decrease in area since Jul 13. The Microcystis bloom extends from Maumee Bay north to Pointe Mouillee State Game Area, MI and to the south to Magee Marsh Wildlife Area, OH and into the western basin past West Sister Island. Sandusky Bay has a local bloom of mixed cyanobacteria. Toxins have been detected above 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, see Mixing Forecast product. --NCCOS HAB Forecasting Team 22 July 2024
