The Microcystis cyanobacteria bloom continues extending in the western basin of Lake Erie from Maumee Bay north along the Michigan coast to Brest Bay, east along the Ohio coast to the Portage River; and up to 13 miles northeast of West Sister Island, nearing the Ontario coast. Mild winds observed since Monday promoted scum formation corresponding to areas of dark red and orange in satellite imagery. Measured toxin concentrations remain above the recreational threshold where the bloom is most dense (appearing green from a boat). Keep pets and yourself out of the water in areas where scum is forming.
