Cowanesque River river
Total streamflow across the Cowanesque River was last observed at 3,580 cfs, and is expected to yield approximately 7,101 acre-ft of water today; about 540% of normal. River levels are high. Average streamflow for this time of year is 663 cfs, with recent peaks last observed on 2021-08-19 when daily discharge volume was observed at 34,470 cfs.
Maximum discharge along the river is currently at the Cowanesque River At Elkland reporting a streamflow rate of 1,990 cfs. This is also the highest stage along the Cowanesque River, with a gauge stage of 19.42 ft at this location. This river is monitored from 3 different streamgauging stations along the Cowanesque River, the highest being situated at an altitude of 1,338 ft, the Cowanesque River At Westfield.

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.

Cowanesque River
The Cowanesque River is a 47-mile-long tributary of the Tioga River in Pennsylvania and New York. It flows through the cities of Westfield, Knoxville, and Lawrenceville. The river is named after the Cowanesque Native American tribe that inhabited the area in the past. The Cowanesque River is known for its hydroelectric power generation, with three hydroelectric dams and reservoirs along its course, namely the Cowanesque Lake, Hammond Lake, and Tioga-Hammond Lakes. These reservoirs and dams help regulate the river's flow and provide flood control. The Cowanesque River is also a popular destination for recreational activities such as fishing, kayaking, and camping. The surrounding lands are utilized for agriculture, including dairy farming, crop cultivation, and grazing.
Track the Cowanesque 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 Cowanesque River
Where does the data for the Cowanesque 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.
