The end of our hundred-yard walk carrying our canoe from the parking lot to the lake ended in something between disgust and dismay when we looked down into the water. The surface of the lake looked nothing like water. It appeared more like green paint — like a bucket of latex ready to be spread on the side of a house. We couldn’t have seen a rock half an inch below the surface, it was so thick and opaque.

Dear Homeward Bound, I’ve been hearing a lot about blue-green algae these days and how it can be dangerous to dogs. What is it and why is it dangerous? Curious Dear Curious, There are lots of reports of this scary phenomenon these days. We did some research to find out some more information for you and learned that the “algae” is not actually a type of algae but a bacteria known as cyanobacteria. Cyanobacteria isn’t visible to the naked eye, but it often gives the appearance of algae when it clumps together in bodies of water. This bacteria is often found in non-flowing freshwater during hot...

CYANOBACTERIA, SUCH AS this green pea soup-like bloom in Lake Champlain, is often mistakenly called blue-green algae. But, unlike algae, cyanobacteria can produce toxins that can be harmful if swallowed.
VERMONT — Warm weather is a welcome sign of summer, but it also creates ideal conditions for cyanobacteria to grow in Vermont waters. Cyanobacteria (sometimes referred to as blue-green algae) are tiny microorganisms. In large numbers they sometimes form blooms on the water’s surface and wash up along shorelines — and can produce toxins harmful to humans and animals. Because State and volunteer citizen monitors have already started to see cyanobacteria blooms forming in Malletts Bay and Missisquoi Bay in Lake Champlain, officials want people to know how to identify a bloom, and to avoid...
