The 2011 blue-green algae monitoring season is winding down. This year following spring flooding, blooms in Missisquoi Bay were extensive and thick. Additional persistent blooms were found in St. Albans Bay and sporadic blooms occurred throughout other portions of the lake. For information about the latest status of algae blooms on Lake Champlain visit LCC’s website or the Vermont Department of Health’s blue green algae page.

Each summer since 2004 LCC has partnered with the University of Vermont Rubenstein Lab, to expand blue green algae monitoring on Lake Champlain. LCC helps train and oversee citizen monitors who take weekly water samples from select shoreline areas. We also monitor several shoreline beaches, do visual site checks at additional locations, and serve as a first responder when blooms are underway. This award-winning program, which LCC initiated, provides critical data on where and when blooms are happening. The information we gather is used by public health officials to assess whether the water is safe for swimming. Our dedicated group of volunteer monitors go out once per week from early July through Labor Day to collect samples and take them to designated drop-off locations.
