Bloom Description

Volunteer reports: Small inlet and extensive shoreline of village residential waterfront. Air 82F water temperature 77.5F. Very still water with no wind. Bright sun. We can’t see the extent of the bloom from our shoreline but we suspect it continues both north and south in our 2 mile zone. It’s at least a large localized bloom but possibly widespread.
