Though school is out for the summer, some kids in the Northeast Kingdom are still learning in a floating classroom. A boatload of Orleans Central Supervisory Union students set sail on Lake Memphremagog Wednesday to learn all about their local watershed. Though Vermonters love this lake for recreation, more than 300,000 people in Canada use Lake Memphremagog as a source of drinking water. It’s one of many reasons that nonprofit Memphremagog Community Maritime is bringing local kids out on the boat for their second season in the floating classroom. While it’s a fun way to learn, advocates of the Memphremagog watershed also hope it shows local kids how much of an impact they have on the environment and why it’s important to preserve it.
