Recent satellite imagery indicates the bloom is present in Maumee Bay, extending north alongshore the Michigan coast to Brest Bay, east past Middle Sister Island and along the Ohio coast to the mouth of the Portage River.
Low concentrations of the bloom are also present within the Bass Islands and east past Kelleys Island to 10 miles outside Sandusky Bay.
Observed winds Tuesday and Wednesday reduced mixing and may have led to scum formation.
Measured toxin concentrations are detectable at all samples sites, but are still below the recreational threshold throughout most of the bloom extent.
