Lake St. Francis dominates the southern portion of this boundary region where the United States and Canada meet. This 2016 survey illustrates the international border along the upper St. Lawrence River, showing the line dividing New York and the United States from Canada. The topography is largely defined by the sprawling water of the lake and its complex shoreline, which transitions into the northern reaches of Franklin County. This map captures a specific modern perspective on the border’s path through these international waters, useful for tracing the precise jurisdictional boundaries of the river system before any subsequent shoreline or water level changes.
