Bloom Description

Volunteer reported: Worst HAB I’ve seen in my zone this season. There was no observable fish die-off. Conditions have been muggy/rainy for the last few days including this morning, but when I was out today it was warm and sunny (~75 degrees F). Blooms were more concentrated closest to the shore, but there were particulates visible in the clearer areas of water.
