Widespread blue green algae bloom intensifies on Canandaigua Lake
Blue green algae popped up early this year on Canandaigua Lake, but the few isolated cases in late June and early July don’t hold a candle to what folks around the lake began noticing Monday.
On Tuesday, a Canandaigua Lake water quality update warned of blue green algae along shorelines and urged everyone (including pets) to avoid “discolored water, streaking of algae, surface scums, or pea soup-like conditions.”
On Wednesday, conditions intensified. Reports of blue green algae came in from areas all around the lake — in some cases with “blooms extending out 100 feet or more offshore,” according to the Canandaigua Lake Watershed Association and Canandaigua Lake Watershed Council.
“We have had numerous small isolated shoreline blooms over the summer,” said Canandaigua Lake Watershed Program Manager Kevin Olvany. “This is really the first lake-wide bloom event.”
“Overall, the summer was a pretty light algae bloom year as compared to previous years,” Olvany added.
More than 70 volunteers with the CLWA Shoreline Harmful Algae Bloom Monitoring Program have been trained to identify blooms and report findings. CLWA Director Lindsay McMillan shared some of the photos from sightings around the lake: Nibawauka Beach and Meadowview on the east side; Menteth Point Shore and north of Butler Road beach on the west side; and streaks of blue green algae seen from a boat headed south toward Granger Point. Marty Gordon shared a drone image of blue green algae covering the area around Walton Point on the west side.
Multiple factors including weather and wind speed influence incidents of blue green algae blooms in the lakes. A Canandaigua Lake watershed update in September noted the significance of documenting the occurrence and severity of blooms. The CLWA and Canandaigua Lake Watershed Council partner with Finger Lakes Institute, Seneca Lake Pure Waters Association and other like-minded groups to learn more.
