Lake Champlain Committee monitors filed over 196 reports this week for Lake Champlain and inland waterways. While there were plenty of reports of clear water, blooms proliferated in parts of Missisquoi Bay, St. Albans Bay, the Inland Sea, Main Lake Central and Main Lake South. Shelburne Pond and Lake Carmi also had reports of cyanobacteria. Several beaches were closed in both New York and Vermont.

We saw a lot of volatility in conditions this week on Lake Champlain. Heavy rains flushed things out in some areas and in others provided additional nutrients to fuel cyanobacteria growth. Blooms showed up along the New York shoreline, in St. Albans Bay, Missisquoi Bay and along the Burlington and South Burlington shorelines and at Vermont inland waterways of Bald Hill Pond and Shelburne Pond. We also received word that two dogs recently died due to ingesting cyanobacteria from a private pond in Vermont.  Please remind dog owners to be vigilant about protecting their pets and keep them away from water with cyanobacteria.

We had over 150 water quality observations from Lake Champlain and inland waterway monitors this week! Most were of good conditions but cyanobacteria was reported from Lake Champlain sites in Malletts Bay, St. Albans Bay and Missisquoi Bay. You’ll find further information and links below about cyanobacteria and how to recognize and report it. We’ve also included a photo of a mystery phenomena we are trying to identify (stay tuned for results next week) and a picture of the invasive fishhook waterflea. Populations of this aggressive, predatory zooplankton have increased dramatically since they were first discovered in Lake Champlain last September.
