Bloom Description

Volunteer reports: Lake is calm, couple of hours following a hard rain, conditions for and evidence of Habs in area for past few days. This is the worst I've seen here since we began monitoring years ago. My neighbors asked me earlier today if this 'pea soup' color across the lake is a huge Hab....I did not know, evidently a pre-curser at least.
