Just recieved this forwarded e-mail from Bill Crenshaw.
This week, we collected from all our sites in Missisquoi and St. Albans Bays and we received a sample from Station 25 from Vermont DEC, and a citizen sample from the Shipyard in Missisquoi Bay.
Although we continue to observe patchy surface clumps of cyanobacteria throughout Missisquoi Bay, this week, only the Rte 78 access was at Alert Level, with about 4,600 potentially toxic cells/mL and a mix of Anabaena, Microcystis and Aphanizomenon. The microcystin concentration was 1.3 µg/L, so we are back at Alert Level 1. We also collected a sample from Donaldson Point that had about 130,000 potentially toxic cells/mL and a mix of Anabaena, Microcystis and Aphanizomenon. Toxins will be run in the next assay.
There is also a Melosira bloom going on in Missisquoi Bay that may be confusing to some –if you aren’t familiar, all algae can look the same.
All other sites tested at the Quantitative Level.
I expect that blooms will continue to come and go as the season winds down and the lake continues to cool. When the winds are calm in the bright sunshine, there will be surface accumulations. At night and with wind, the algae will be dispersed. Duck hunters should continue to be vigilant and keep their dogs out of the water if they see any visible algae in the water.
