To help us increase our understanding of the cyanobacteria dynamics in Canandaigua Lake and to provide public notification on the safety of the water, CLWA is working with the Canandaigua Lake Watershed Council (CLWC), the Finger Lakes Institute (FLI), Seneca Lake Pure Waters Association, and the New York State Department of Enviornmental Conservation (NYS DEC) on a Shoreline Harmful Algae Bloom Monitoring Program.

Volunteers are trained to visually observe blooms and collect water samples for analysis on a weekly basis, from August through October. They record their findings online using a system developed by the Seneca Lake Pure Waters Association. Volunteer reports and sample results help us assess overall lake conditions, and allows us to send timely public notifications about our water quality during the bloom season. Findings are reported on our website, Facebook page and in our email blasts.

All data collected through this program is shared with statewide and local researchers, and contributes to the ongoing research efforts to monitor Canandaigua Lake.

2020 Interactive Bloom Map

This interactive 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, with yellow equaling “Small Localized Bloom”, orange equaling “Large Localized Bloom”, and red equaling “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.

How you can report suspicious blooms

Help by collecting information on blooms:

  • Location (GPS coordinates, address, or geographic description of the area )
  • Photos
  • Description – Was it streaky, globby, thread-like, like spilled paint, like pea soup, scummy, silky, or have small leaves? What color was it?
  • How large of an area did it cover?
  • How long was it there?

Report Suspected Blooms to HABs@canandaigualakeassoc.org.

Trained Volunteers can use this link to report the activty in their zones.
