Quinnipiac River river
Total streamflow across the Quinnipiac River was last observed at 116 cfs, and is expected to yield approximately 230 acre-ft of water today; about 52% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 224 cfs, with recent peaks last observed on 2011-08-29 when daily discharge volume was observed at 3,943 cfs.
Maximum discharge along the river is currently at the Quinnipiac River At Wallingford reporting a streamflow rate of 104 cfs. However, the streamgauge with the highest stage along the river is the Quinnipiac River At Southington with a gauge stage of 2.98 ft. This river is monitored from 2 different streamgauging stations along the Quinnipiac River, the highest being situated at an altitude of 145 ft, the Quinnipiac River At Southington.

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.

Quinnipiac River
The Quinnipiac River is a 45-mile long river located in the eastern part of Connecticut, USA. The river was historically used for transportation and trade by Native American tribes and later by European settlers. The river's hydrology is affected by urbanization, agriculture, and industrialization. There are four major reservoirs/dams on the river, including the Barnes Memorial Reservoir, the Hanover Pond Dam, the Southington Reservoir, and the North Branford Reservoir, which provide drinking water to the surrounding communities. The river is also used for recreational activities such as fishing, boating, and hiking. While agricultural use has declined, there are still some farms in the river's watershed that use its water for irrigation. The Quinnipiac River has faced environmental challenges, including pollution, which has affected its water quality and wildlife.

About the Quinnipiac River
Where does the data for the Quinnipiac 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.
