Zebra Mussels Detected in US Waters of Lake Memphremagog

MONTPELIER — After several sampling seasons, Vermont Department of Environmental Conservation (DEC) scientists, consultants, and local partners have detected zebra mussels in United States (US) waters at Lake Memphremagog. Native to Eastern Europe, zebra mussels (Dreissena polymorpha) are small, invasive shellfish that can quickly form large populations and outcompete native species for food and habitat. Currently, zebra mussels are found only in Lake Champlain and Lake Bomoseen in Vermont.
