We are getting reports of shoreline cyanobacterial harmful algal blooms (cyanoHABs) along the shoreline of Canandaigua Lake. The last few days of hot temperatures and very light winds have provided favorable conditions for cyanobacteria to proliferate and accumulate along the shoreline. The extent of the blooms may go along many properties. See the images below, which were taken this afternoon.

 

 

 

 

 

 

 

 

Most of the blooms have been reported along the east side of Canandaigua Lake, but we just received a report along the west side at 2:15 PM.

Both volunteers and watershed staff have been out reporting the extent of the conditions and several samples have been collected, which will be sent for analysis at the Finger Lakes Institute in Geneva. However, we know based on previous year’s results that blooms have the potential to produce high toxins, so please exercise caution and avoid areas that have green discolored water, surface streaking, a pea-soup like appearance, or scums. Be especially careful with pets!

Please check out the resource list below for further reading on cyanoHABs.
