Total streamflow across the Missisquoi River was last observed at 1,385 cfs, and is expected to yield approximately 2,747 acre-ft of water today; about 39% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 3,570 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 1,810 cfs. However, the streamgauge with the highest stage along the river is the Missisquoi River Near East Berkshire with a gauge stage of 4.52 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.

Profile

Streamflow elevation profile

Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

About this river

Missisquoi River

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.

FAQ

About the Missisquoi River

Where does the data for the Missisquoi River come from?

Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.

How is "percent of normal" calculated?

Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).

Why are some gauges showing very different flows?

Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.

What's the elevation profile chart showing?

Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.

Can I get alerts when a specific gauge crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
