Memphremagog Conservation Inc. (MCI) is a not-for-profit organization whose mission since 1967 is to protect the environmental health and preserve the natural beauty of Lake Memphremagog and its watershed. Made up of volunteers and with the strength and support of its members, MCI has worked diligently so that all the residents of the region, permanent and seasonal, waterfront or not, can enjoy the lake today and tomorrow, in harmony with nature.

Situated in the southern part of the Eastern Townships and crossed by the Canadian-American border, Lake Memphremagog is the largest body of water in the region. More than 170,000 people, representing more than 90% of the population of Sherbrooke, Magog, Omerville, Deauville, Ste-Elie and Lennoxville, get their drinking water from the lake. The wide range of recreational activities available attracts a large number of tourists and locals alike every year, making it a major tourist draw in the Eastern Townships.

Unfortunately, the signs of deterioration of Lake Memphremagog are clear: cyanobacteria blooms since 2006, the proliferation of aquatic plants and algae, the decline in water quality evidenced by a reduction in water clarity, a decline in the amount of oxygen in the water and an increase in sediments. The major cause of the deterioration of the lake is without a doubt excessive phosphorus loading. There are many sources of phosphorus, primarily resulting from human activities, of which agriculture, forestry and urbanization are the main culprits.


Give us a hand! You are part of the solution!
