2024 Shoreline HABs Monitoring Program
Seventy trained volunteers around Canandaigua Lake and Watershed staff will be reporting current water conditions from August through the beginning of October. While it is not possible to document every bloom occurring on the lake in real time, trained observer reports help us bring you the most up to date information available.

The six Canandaigua Lake water purveyors (the City of Canandaigua, the Village of Newark, the Village of Palmyra, the Village of Rushville, the Town of Gorham, and Bristol Harbour) are working alongside the Geneva District Office of the Health Department and the New York State Department of Health to monitor the public drinking water for the presence of toxins associated with harmful algal blooms. Samples of the public drinking water are routinely collected and sent to a State approved laboratory on a regular basis during the harmful algal bloom season to determine if toxins are present.
