Bloom Description

Volunteer reported: There was a small bloom along north edge of Taughannock marina (see photos). I also found some small signs of bloom at one end of the swimming beach, near the pier, but the rest of the beach seemed to be clear. I don't know if these two locations were the same bloom or not, but they were there on the same day. Very still and clear water, lots of cut eel grass floating.
