Bloom Description

Volunteer Reports: Open Water HAB; SW wind during the day creating some foam streamers. Wind stopped, hot and sunny. Worst HABs we have ever seen. Very thick. Stayed mainly on Cayuga side of the channel. My actual shoreline was clear for 10’ and we noticed slight HABs from our dock. The further from shore we got, the thicker it became. Worst yet! Still bad when we returned at 6:45.
