Researchers are using a low-tech tool to track blue-green algae blooms in Lake Champlain.
Today they are releasing 200 oranges in Missisquoi Bay to determine where the wind and currents steer them.
They want to know if the algae in the bay flow south and form other blooms nearby.
And they want the public’s help. Anyone spotting a floating orange in the lake this summer is asked to call the state University of New York’s College of Environmental Science and Forestry at 518-564-3038.
Some varieties of blue-green algae produce dangerous toxins. No human illnesses have been reported after coming into contact with the algae, but at least two dogs died several years ago.
