Missisquoi River

The Missisquoi River is a tributary of Lake Champlain, approximately 80 mi (130 km) long, in northern Vermont in the United States and southern Quebec in Canada. It drains a rural area of the northern Green Mountains along the Canada–US border northeast of Lake Champlain, and an area of Quebec's Eastern Townships. The South Branch rises in Vermont and runs generally from southeast to northwest; the North Branch rises in Lake d'Argent in Eastman, Quebec, and runs from north to south. The North Branch and the South Branch join at Highwater, Quebec, just downriver from North Troy, Vermont. The river then runs in Quebec for approximately 15 miles (24 km), re-entering Vermont at Richford and thence to Lake Champlain's Missisquoi Bay.

The name of the river is derived from an Algonquian Abenaki word "Masipskoik", meaning "[Place where there are] Large Rocks", referring to boulders found at the river's alluvial fan..

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.
