Water Quality update for Friday, September 20th 2024

Substantial cyanobacterial Harmful Algal Blooms (cyanoHABs) continue to be observed in multiple areas around Canandaigua Lake. Today’s reports are primarily coming from the east side, with a few sightings starting to be reported on the west side as well. However, if winds shift, we may get more reports from the west side.

Canandaigua Lake is now experiencing its 11th consecutive day of cyanoHAB reports, marking an active bloom situation. We urge the community to continue using visual cues before entering the water or allowing pets to swim. Please put safety at the forefront of your mind.

This is not just a local issue; many of our neighboring Finger Lakes are also facing substantial bloom events. While the research on the increasing frequency and severity of these blooms is still evolving, we know that factors such as climate change, polluted stormwater runoff, and the impacts of invasive species (like quagga and zebra mussels) play key roles.

For more information on the contributing factors to these blooms, we encourage you to revisit an article by Canandaigua Lake Watershed Program Manager Kevin Olvany. While written a few years ago, it provides valuable insight into the threats to watershed health and the factors influencing the onset of cyanoHABs.

Finally, we’d like to extend our heartfelt thanks to our incredible volunteers, who have gone above and beyond in monitoring these blooms—many well beyond their original commitments! Their dedication is a true testament to our community’s passion for protecting Canandaigua Lake. Their efforts feed directly into the interactive map on the CLWA website, providing real-time data for everyone to stay informed.

Thank you for your continued vigilance and support.
