Studies
Since 1972, MCI has been active in protecting the environmental health of Lake Memphremagog. These efforts have led to the production of numerous studies by MCI and its partners, presented in the form of reports, on different subjects related to the Lake Memphremagog watershed. We invite you to learn more by consulting these reports.
