Lake Memphremagog

Lake Memphremagog is a transboundary freshwater lake straddling southern Quebec and northern Vermont, known for its long, narrow shape and shared shoreline. The lake connects to the Magog River at its northern end and provides boating and fishing opportunities on both sides of the border.

The lake offers extensive boating, fishing and shoreline recreation, with towns such as Magog (Quebec) at the north and Newport (Vermont) at the south serving as principal access points and service centres. Province Island is an internationally divided island in the lake and is a local point of interest.

Lake Memphremagog was formed by glacial processes and has long been used for navigation and fisheries by communities on both sides of the border; towns developed along its shores in the 19th and 20th centuries. It remains managed for recreation, water quality and cross-border stewardship.

Geographically it lies in the Eastern Townships of Quebec and the Northeast Kingdom region of Vermont, extending roughly 50 kilometres across the border between the town of Magog and the city of Newport.

• Cross-border lake: Extends across the border between Quebec and Vermont, with both Canadian and U.S. towns providing public access and services.
• Length: Length of roughly 31 miles (about 50 kilometres) end to end, with multiple public boat launches at Magog (QC) and Newport (VT).
