Cyanobacteria (blue-green algae)

Climate Change is Impacting Drought in Vermont Drought is a prolonged dry period caused by less than normal rainfall or snowfall for an extended period of time. Drought can lead to water shortages, meaning there is less water available for...

Public Health GIS Maps The Health Department supports several web apps that address important public health issues using GIS technology. Some example use cases are: See if cyanobacteria blooms might affect your summertime water recreation plans. Find out if others...

As temperatures in Lake Champlain and other fresh water bodies continue to warm due to climate change, and with more heavy precipitation, conditions will become more favorable for blooms to occur.

Responding to climate change will benefit health now.

Changes in the climate can affect human health, including: effects from extreme heat, extreme weather events, tickborne and-mosquito-borne diseases, cyanobacteria (blue-green algae) blooms, and air quality.

The Cyanobacteria (Blue-Green Algae) Tracker allows the public to check recent cyanobacteria bloom reports at shoreline sites and recreational swimming areas of Lake Champlain and various inland lakes in Vermont.

Cyanobacteria, also known as blue-green algae, are common in Lake Champlain and other Vermont waters. Some types of cyanobacteria can release natural toxins or poisons (called cyanotoxins) into the water.

Not all Vermont bays, lakes, and ponds are monitored. Be aware of changing conditions, and keep out of the water if you think cyanobacteria may be present. Check recent reports on lake conditions and season summaries. To find out if...
