    Over 57 years protecting Lake Memphremagog

    In 1967, realizing the extent of degradation of Lake Memphremagog, three shoreline residents founded MCI. Since then, there have been many members of the Board of Directors and many presidents, and hundreds of volunteers following in their footsteps, who each in their own way, have helped to improve the lake. Today, MCI continues to promote good environmental practices, apply solutions on the ground and be present in lakeside municipalities.
