Bloom Description

Volunteer reported: Lake has been a distinct green for the past 3-4 days. Very widespread. Today has the consistency of pea soup along shoreline but is starting to mix in the breeze that has come up. Was on the MV Teal yesterday (7-11) for a water sampling cruise, had a sample under the microscope and could clearly see Dolichospermum in big quantities.
