Weekly Water Quality Updates

2025 Interactive cyanoHAB Map for Canandaigua Lake

The interactive bloom map and volunteer program reporting is thanks to a partnership with Seneca Lake Pure Waters.

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.

Map tips:

  • Reported blooms are represented by the colored dots
    • Red dots represent a “Small Localized Bloom”
    • Blue dots represent a “Large Localized Bloom”
    • Purple dots represent a “Widespread Bloom”
  • Clicking on a dot will bring up a window with data associated with the reported bloom as well as links to any photos.

This interactive map and volunteer program reporting is thanks to a partnership with Seneca Lake Pure Waters.
