ALGAE BOOM UPDATE….. (please read, important information)
Good Afternoon –
The near shore CSLAP sample taken on 9/9/17 from the sampling point at the deepest point in Silver Lake CONFIRM the presence of an Open Water cyanobacteria HAB in Silver Lake based on blue-green chlorophyll a levels of 32.2 µg/L (above the DEC Confirmed Bloom threshold of 25 µg/L) and a microscopic analysis of Trace Microcystis, Woronichinia, and Centric Diatoms.
Toxin data are NOT yet available, but will be forwarded upon receipt IF they indicate an elevated risk.
However, even if the toxin levels are low, the same advisory information applies – lake residents, visitors and pets should avoid exposure to any surface scums or heavily discolored water, should seek medical assistance as needed if any exposure symptoms are experienced, and should report these symptoms to their local health department and to email@example.com.
Any questions or comments may be sent to HABsInfo@dec.ny.gov.
As always, please consult the DEC (http://www.dec.ny.gov/chemical/77118.html) and DOH (http://www.health.ny.gov/…/water/drinking/bluegreenalgae.pdf) web sites for additional information on what to do if you see or encounter blooms. The Silver Lake Association (http://silverlakeassociation-wny.org/) web site and Facebook page will also have updates.
As warranted I will report back to you.
This situation will eventually dissipate as conditions for bloom growth deteriorate.
