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, and record their findings online using a system developed by 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.

2021 Canandaigua Lake Water Quality Updates

Each Friday, CLWA along with our partners at the Candandaigua Lake Watershed Council post updates on the current lake conditions.

2021 Interactive Bloom Map

The 2021 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.
      • 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.

2021 Bloom Status

This summer, CLWA has 70 trained volunteers monitoring the Canandaigua Lake shoreline. Volunteers report on a Monday – Sunday window for a total of 9 weeks.

The below table highlights the number of surveys and the number of blooms for the current week, previous week, and total for the entire season thus far.

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.

665 Volunteer Hours

Between program planning, attending trainings, performing weekly surveys, water sampling, and driving to labs to submit samples for analysis, our dedicated group of volunteers put in a total of 665 hours to support our HABs program in 2020. We thank each and every one for their commitment to the program!
