Tioga River river
Total streamflow across the Tioga River was last observed at 5,915 cfs, and is expected to yield approximately 11,732 acre-ft of water today; about 176% of normal. River levels are high. Average streamflow for this time of year is 3,359 cfs, with recent peaks last observed on 2021-10-30 when daily discharge volume was observed at 39,790 cfs.
Maximum discharge along the river is currently at the Tioga River Near Erwins Ny reporting a streamflow rate of 3,200 cfs. However, the streamgauge with the highest stage along the river is the Tioga River At Tioga Junction with a gauge stage of 9.24 ft. This river is monitored from 5 different streamgauging stations along the Tioga River, the highest being situated at an altitude of 1,126 ft, the Tioga River Near Mansfield.

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.

Tioga River
The Tioga River is a 58-mile long river located in north-central Pennsylvania, in the United States. The river is known for its scenic beauty and recreational opportunities, including fishing, canoeing, and kayaking. The river's hydrology has been heavily impacted by the construction of several reservoirs and dams, including the Hammond Lake and the Cowanesque Lake, which were built in the mid-twentieth century for flood control and water supply purposes. The Tioga River has a rich cultural and historical significance, as it was an important transportation route for the indigenous peoples and early settlers. Today, the river is used for agricultural purposes, including irrigation and livestock watering. The river remains an important natural resource for the surrounding communities, and efforts continue to protect and preserve its water quality and ecosystem.

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