Missisquoi River The Missisquoi River rises near the town of Lowell, flows northward into Canada crossing the border at North Troy, returns to the United States at East Richford, Vermont and then follows a westerly direction to Lake Champlain. The highest point in the watershed is Jay Peak at elevation 3,861 feet. The watershed drains 855 square miles of which 619 square miles are in Vermont and 236 square miles are in Canada. Its length is about 88 miles. The major tributaries include Black Creek, Tyler Branch, and the Trout River, which come from the south, and Mud Creek and the North Branch, which flow from the north. The Upper Missisquoi is the stretch from the junction of Burgess Branch and the East Branch northwest of Lowell village to the Canadian border in North Troy. From the confluence of these two branches, the Missisquoi River flows in a northerly direction. As it flows into the town of Westfield, Snider Brook joins the river. About three and a half miles downstream, the river passes east of Westfield village and Taft Brook enters the river. In another four miles, Beetle Brook flows into the river. The river flows over Phelps Falls dam and then north still with Jay Branch, which carries the flow of its watershed as well as that of its tributary Crook Brook, joining the river from the west. The
