Weekly Water Quality Updates
2025 Interactive cyanoHAB Map for Canandaigua Lake
PLEASE NOTE: Water quality conditions can change daily, if not hourly. This map serves as a record of the reports that have come in this season and may not indicate current lake conditions. Please continue to use your visual indicators and look for suspicious algal activity before recreating in the lake. If no blooms are observed during the sampling week, then no markers will appear.
This interactive map and volunteer program reporting is thanks to a partnership with Seneca Lake Pure Waters.
