Champlain wishes

The waters of Lake Champlain are clearer than they've been for a long time, but few people are happy about it. That's because the water clarity can be attributed to a burgeoning population of zebra mussels (Dreissena polymorpha). As reported by The Barre Montpelier Times Argus, divers are unhappy because while they can see further under the water, a lot of what they are seeing is covered with mussels. There is also concern that this notorious invasive aquatic species could be endangering the historic shipwrecks at the lake bottom, one of the main reasons that divers visit the lake.
