Bloom Description

Volunteer Reports: Lake has been very calm today up until maybe 20 minutes ago. Was very flat when I took the pictures. Wind has come up a little while trying to fill out this report and get pictures transferred. Bloom extends as far as I can see in either direction when I go out on the dock. Has been raining the past few days. HABS worst near shore. Solid on shore and streaks a bit further out.
