2021 HABs Week 3 Results

08/24/2021 7:49 PM | Kaitlin Fello (Administrator)

We had no confirmed blooms last week, but we did have one report on Saturday where photos showed cyanobacteria present. We didn’t believe it was dense enough to be a bloom per the NYS DEC definition of ≥ 25 µg/L of blue-green Chlorophyll. Friday through Sunday found excellent bloom conditions, but we still are not seeing them pop up. Volunteers continue to monitor around the lake.

Other lakes have started seeing blooms again, including Canandaigua, Cayuga, and Keuka. Blooms have affected beaches in some locations.
