Monongahela River river
Total streamflow across the Monongahela River was last observed at 38,600 cfs, and is expected to yield approximately 76,562 acre-ft of water today; about 125% of normal. River levels are high. Average streamflow for this time of year is 30,958 cfs, with recent peaks last observed on 2018-02-17 when daily discharge volume was observed at 219,000 cfs.
Maximum discharge along the river is currently at the Monongahela River At Elizabeth reporting a streamflow rate of 21,100 cfs. However, the streamgauge with the highest stage along the river is the Monongahela River Near Masontown with a gauge stage of 12.55 ft. This river is monitored from 2 different streamgauging stations along the Monongahela River, the highest being situated at an altitude of 765 ft, the Monongahela River Near Masontown.

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.

Monongahela River
The Monongahela River is a 128-mile-long river located in West Virginia and Pennsylvania. It was named after the Monongahela people who previously inhabited the area. The river played a significant role in the early industrialization of the United States, with coal being transported downstream to Pittsburgh. Today, the river is still vital for transportation, as well as for hydroelectric power generation. The river has several reservoirs and dams, including the Youghiogheny Dam and Reservoir and the Morgantown Lock and Dam. These structures help regulate water levels and provide recreational opportunities such as fishing, boating, and swimming. The Monongahela River is also important for agriculture, assisting in irrigation for crops in the surrounding areas.

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 Monongahela River
Where does the data for the Monongahela 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.
