Bloom Watch Update on Seneca Lake


Observation Dates: September 8-11,2018
Zones Monitored: 65 of 75 zones
Shoreline Coverage: 50 miles

Suspicious Blooms: 9
Confirmed Blooms: 2

Warm water, warm air and calm waters continue to promote bloom activity on Seneca Lake. Our volunteer reports, the hotline calls and emails all support the fact that we have entered the peak activity period for blooms. This timing pattern is very similar to what we experienced around the lake last year. September seems to be the month for ideal bloom conditions. Although some areas show more bloom activity than others, it is good to assume all areas of the lake have and will experience blooms.

Last week, volunteers submitted water samples from 9 "suspicious" blooms. The New York State Department of Environmental Conservation (NYSDEC) confirmed the presence of a cyanobacteria Harmful Algal Blooms (HABs) in two of the water samples taken from the southeast region of Seneca Lake near Lodi. We are waiting for the confirmation regarding the remaining 7 water samples.

Please refer to the Seneca Lake Interactive HABs map for the most up-to-date HABs information including the locations of:

HABs are identified by observing the water conditions, if you see green dots, green streaks, a spilled paint or pea soup appearance - AVOID contact with the water! Keep studying the water surface in your area and you will begin to become very comfortable identifying blooms. The ability to spot blooms forming is the key to keeping your family and pets safe, remember if your "IN DOUBT - STAY OUT!"

Thanks again for to all of our volunteers for 7 weeks of monitoring activities. I would also like to thank all of our lakeside residents for all the calls and emails looking for information and assistance. Given the nature of the requests, it is clear that HABs awareness within our community is really ramping up. This awareness is you major tool for protecting yourself and your family from any hazards associated with HABs. Stay HABs safe this week.
