Bloom Description

Small inlet along residential shoreline in village of Cayuga. Completely still water, no wind, cloudy 67 degrees. Water temperature was 76.5 F. We have had a break from frequent HABs for the month of August so far, though the weather has been hot until yesterday. We also have had more wind in past weeks which kept the water churned up some days and more active on the surface. The bloom seems to still be progressing as we continue to observe it
