After a “quiet” week with minimal harmful algal bloom reports from volunteers and the public, activity picked back up again today, with several reports and samples collected from the west side of the lake. Photos coming in showed areas of surface streaking and shoreline accumulations of algae from several spots around the lake.  We are starting to get more algae bloom reports from the southern half of the lake. 

And while the sunny, calm, warm weather forecasted for the next several days will be great for getting in those end-of-summer activities, it is also ideal conditions for blue green algae (cyanobacteria) to pop up.  As we cannot predict when or where blooms may appear, please continue to use your visual indicators before recreating in the lake.

September has been the month when we have experienced our most significant bloom events, and last year was no exception, with many blooms being designated as “Confirmed with High Toxins”. This year, the DEC will not be releasing tox...

Yesterday we experienced significant streaking and surface scum accumulations of blue green algae (cyanobacteria) along several shoreline areas. Twelve samples were collected as part of the shoreline HABs network and were brought to the Finger Lakes Institute for screening with the Fluoroprobe. If samples come back with high levels of blue-green chlorophyll a through this screening process (confirming bloom status), they will be sent on to the DEC’s designated lab for toxin analysis. While FLI results should be forthcoming in a few days, the toxin analysis can take much longer. This emphasizes the need to use extreme caution when recreating in the lake.

Although yesterday’s blooms were not experienced lake-wide, the areas they were observed were severe in some cases. Reported blooms were seen in coves, shallow beach areas, by docks, or trapped in corners of a break wall – all areas where blooms get pushed by wave and wind action. Unfortunately, these easy-access areas are also where pe...
