Total streamflow across the Missisquoi River was last observed at 721 cfs, and is expected to yield approximately 1,430 acre-ft of water today; about 25% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,893 cfs, with recent peaks last observed on 2014-04-16 when daily discharge volume was observed at 48,450 cfs.

Maximum discharge along the river is currently at the Missisquoi River At Swanton reporting a streamflow rate of 354 cfs. However, the streamgauge with the highest stage along the river is the Missisquoi River Near East Berkshire with a gauge stage of 2.64 ft. This river is monitored from 3 different streamgauging stations along the Missisquoi River, the highest being situated at an altitude of 598 ft, the Missisquoi River Near North Troy.

The Missisquoi River is a 80-mile-long tributary of Lake Champlain that flows through Vermont and Quebec. It was a crucial trade and transportation route for Native American tribes and early European settlers. The river has a hydrological history of flooding and ice jams, which led to the construction of several reservoirs and dams, including the Gorge Dam and Enosburg Falls Dam. These dams have helped to regulate water flow, prevent flooding, and generate hydroelectric power. The river is used for recreational activities such as fishing, kayaking, and swimming. It also supports agriculture, with farms located along its banks using its water for irrigation. The Missisquoi River is an important part of Vermont's history and provides valuable resources to the surrounding communities.

History of the 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.
