Clarion River river
Total streamflow across the Clarion River was last observed at 9,212 cfs, and is expected to yield approximately 18,272 acre-ft of water today; about 230% of normal. River levels are high. Average streamflow for this time of year is 3,998 cfs, with recent peaks last observed on 2014-05-22 when daily discharge volume was observed at 76,850 cfs.
Maximum discharge along the river is currently at the Clarion River Near Piney reporting a streamflow rate of 3,260 cfs. However, the streamgauge with the highest stage along the river is the Clarion River At Ridgway with a gauge stage of 7.73 ft. This river is monitored from 4 different streamgauging stations along the Clarion River, the highest being situated at an altitude of 1,426 ft, the Clarion River At Johnsonburg.

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.

Clarion River
The Clarion River is a 110-mile-long river located in western Pennsylvania, United States. The river has a rich history, as it was used for transportation by Native Americans and later settlers. The first oil well in the United States was drilled along the river's banks in 1859. The river is fed by numerous tributaries and has a drainage area of 1,110 square miles. Several reservoirs and dams are located on the river, including Piney Dam, East Branch Dam, and Clarion River Lake. These structures provide flood control, water supply, and recreation opportunities such as boating, fishing, and camping. The river also serves as a source of drinking water for several municipalities and supports agricultural activities such as crop irrigation and livestock watering.

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