Widespread Blooms Reported on Monday, October 2, 2023

We have received several reports of cyanobacterial harmful algal blooms (cyanoHABs) along the shoreline of Canandaigua Lake today. Areas reporting blooms include Vine Valley, Deep Run, Ontario Beach Park, Kershaw Park, and many private residences. We also received a report of a bloom area mid-lake as well.

Please avoid swimming or letting pets swim in blooms. Based on previous results, we know that blooms can produce high toxins, so please exercise caution and avoid areas with green discolored water, surface streaking, a pea-soup-like appearance, or scums. Several public access areas have been roped off to protect public health.

Please email HABs@canandaigualakeassoc.org with any questions.
