Algae Bloom Information Update…
Good Morning –
The near shore CSLAP sample taken last week from the Silver Lake Campground (Lake Shore Dr., Castile; near Mack’s) lab results confirm the presence of a cyanobacteria harmful algae bloom (HAB) in Silver Lake (Wyoming Co.) based on blue-green chlorophyll a levels of 178,069 µg/L (above the DEC Confirmed Bloom threshold of 25 µg/L) and a microscopic analysis of very dense Microcystis, Mod. Planktothrix.
Toxin results will be forwarded upon receipt. 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 firstname.lastname@example.org.
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.
I will report back to you when I have more information.
Again, cyanobacteria harmful algae blooms have been confirmed within Silver Lake; one should assume that bloom conditions exist at other locations in Silver Lake.
This situation will eventually dissipate as conditions for bloom growth deteriorate.
