Total streamflow across the Quinebaug River was last observed at 1,649 cfs, and is expected to yield approximately 3,271 acre-ft of water today; about 58% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,832 cfs, with recent peaks last observed on 2023-12-19 when daily discharge volume was observed at 24,774 cfs.

Maximum discharge along the river is currently at the Quinebaug River At Jewett City reporting a streamflow rate of 663 cfs. This is also the highest stage along the Quinebaug River, with a gauge stage of 5.83 ft at this location. This river is monitored from 6 different streamgauging stations along the Quinebaug River, the highest being situated at an altitude of 614 ft, the Quinebaug R Bl E Brimfield Dam At Fiskdale.

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

Quinebaug River

The Quinebaug River is a 69-mile-long river located in the northeastern part of the United States, mostly in the state of Connecticut. The river has a rich history, having been used for transportation, industry, and recreation. The Quinebaug River also has several reservoirs and dams, including the West Thompson Dam, which was built in the 1960s for flood control and water supply. The river is a popular spot for fishing and canoeing, and there are also several parks and trails along its banks. In terms of hydrology, the Quinebaug River is part of the Thames River watershed and contributes to the overall health of the Long Island Sound. The river is also used for agricultural purposes, such as irrigation and livestock watering.

FAQ

About the Quinebaug River

Where does the data for the Quinebaug 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.
