Today’s calm weather means we may get more reports from other areas of the lake as the day progresses. Please keep an eye out for signs of surface streaking of algae, heavy “dots in the water”, surface scums, or green/discolored water. These areas should be avoided.

Based on past sampling efforts in Canandaigua Lake, we know that the cyanobacteria blooms can produce high toxins, so it is best to avoid contact with all blooms.  Please also use caution before letting dogs in the water. Pets (especially dogs) are very susceptible to the toxins associated with blooms as they are likely to drink surface waters when swimming and may also be exposed when grooming themselves after a swim in the lake. For more information on Dogs and HABs, please check out this informational brochure.
