The Vermont Department of Environmental Conservation's Watershed Management Division monitors the water quality of lakes, ponds, rivers, streams and wetlands across Vermont.
Cyanobacteria (also known as blue-green algae) are common native algae in lakes, ponds and rivers around the world. In Vermont, they can be found in any water body or river. Some species of cyanobacteria produce toxins and these toxins have been documented in some Vermont lakes. Not all algae blooms include cyanobacteria and cyanobacteria aren’t always toxic.
The Vermont Department of Environmental Conservation (VTDEC), in cooperation with the Lake Champlain Basin Program, initiated the Lake Champlain Zebra Mussel Monitoring Program in 1994 to track the zebra mussel's distribution through the lake. Reports are provided annually.
