A dedicated group of volunteers created Memphremagog Conservation in 1967 and has been working ever since to protect the lake.

Unfortunately, Lake Memphremagog is suffering from premature aging, a process which is accelerating. This was established by the MCI-RAPPEL studies¨Operation Healthy Lake 2004-2005¨. (lien vers les rapports aux archives //link to the archived reports). The signs of deterioration are clear: blue-green algae bloom since 2006, the proliferation of aquatic plants and algae, the decline in water quality through lack of water clarity, a decline in the amount of oxygen in the water and an increase in sediments.

However, the major cause in the deterioration of the lake is without doubt excessive PHOSPHORUS loading. Experts agree that there are many sources of phosphorus, primarily resulting from human activities, of which agriculture, forestry and urbanization are the main culprits.

All residents of the watershed are affected. We all must act now to reduce the sources of phosphorus.

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