The cyanobacteria bloom is present in western Lake Erie but cloud cover or winds above 9.0 mph prevent determining the area. The cyanobacteria bloom is present in the western basin from Stony Point, MI to the Magee Marsh Wildlife Area, OH. The bloom extends into the basin to West Sister Island National Wildlife Refuge, OH. Highest concentrations (red and orange in image) are observed in Maumee Bay and just offshore up to Monroe. Weekly high resolution imagery of Maumee Bay can also be found at the Demonstration Great Lakes (20m) HAB Monitoring Page. Toxins have been detected above the recreational limit in western Lake Erie. 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. -- Owens, Hounshell 14 Sep. 2026
