Missisquoi River - Course

Course

The South Branch of the Missisquoi rises in western Orleans County, Vermont, southwest of Lowell near Belvidere Mountain, then flows north past Troy and North Troy entering Quebec at Highwater, where it joins the North Branch. The North Branch of the Missisquoi rises in Lake Eastman, Quebec, and runs about 25 miles (40 km) through Eastman, Bolton Centre, East Bolton, South Bolton, and Mansonville, before joining the South Branch at Highwater, Quebec. The Missisquoi then loops to the southwest through Dunkin and Glen Sutton, Quebec, to reenter Vermont at East Richford in northeastern Franklin County.

It flows west through northern Franklin County approximately 10 miles (16 km) south of the Canadian border, past the small communities of Richford, East Berkshire, Enosburg Falls, and Sheldon Springs. On the west side of Interstate 89 in northwestern Franklin County, it turns to the north, passing through Missisquoi National Wildlife Refuge in its lower 5 miles (8 km) before entering the south end of Missisquoi Bay, an arm of Lake Champlain that straddles the Canadian-Vermont border.
