Cyanobacteria Conditions in Vermont's Waters
Cyanobacteria, also known as blue-green algae, are naturally found in fresh water in the U.S. and in Lake Champlain and other Vermont waters. Some types of cyanobacteria can release natural toxins or poisons (called cyanotoxins) into the water, especially when they die and break down. People and pets should stay away from cyanobacteria blooms. Learn more about cyanobacteria

Information on lake conditions is provided by a network of volunteers trained and coordinated by the Lake Champlain Committee and by scientists from the Vermont departments of Health and Environmental Conservation. Monitors submit weekly visual observations of water conditions from sites around Lake Champlain.
