Winooski River river
Total streamflow across the Winooski River was last observed at 2,231 cfs, and is expected to yield approximately 4,425 acre-ft of water today; about 69% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 3,211 cfs, with recent peaks last observed on 2023-07-12 when daily discharge volume was observed at 48,030 cfs.
Maximum discharge along the river is currently at the Winooski River Near Essex Junction reporting a streamflow rate of 4,650 cfs. However, the streamgauge with the highest stage along the river is the Winooski River At Montpelier with a gauge stage of 5.46 ft. This river is monitored from 2 different streamgauging stations along the Winooski River, the highest being situated at an altitude of 510 ft, the Winooski River At Montpelier.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

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.

Winooski River
The Winooski River is a 90-mile-long river that flows through Vermont. It has a rich history, serving as a major transportation route for Native Americans and early settlers. Today, it is an important source of hydroelectric power and provides recreational opportunities such as fishing, kayaking, and swimming. There are several reservoirs and dams along the river, including the Waterbury Dam, which helps regulate water flow and prevent flooding. Agricultural uses include irrigation for crops and pastures. The river's hydrology is affected by seasonal rainfall and snowmelt, making it susceptible to flooding during high water events. The Winooski River provides a vital resource for both humans and wildlife in the region.
Track the Winooski River in the Snoflo app
Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Winooski River
Where does the data for the Winooski 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.
