Genesee River river
Total streamflow across the Genesee River was last observed at 12,317 cfs, and is expected to yield approximately 24,430 acre-ft of water today; about 133% of normal. River levels are high. Average streamflow for this time of year is 9,231 cfs, with recent peaks last observed on 2014-05-17 when daily discharge volume was observed at 36,850 cfs.
Maximum discharge along the river is currently at the Genesee River At Avon Ny reporting a streamflow rate of 5,370 cfs. This is also the highest stage along the Genesee River, with a gauge stage of 14.08 ft at this location. This river is monitored from 4 different streamgauging stations along the Genesee River, the highest being situated at an altitude of 1,479 ft, the Genesee River At Wellsville Ny.

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.

Genesee River
The Genesee River is a 157-mile-long river that runs through western New York State. The river has played an important role in the region's history, serving as a transportation route for the Seneca people and as a source of power for early settlers. Today, the river is used for a variety of recreational activities, including fishing, boating, and hiking. There are several reservoirs and dams along the river, including the Mount Morris Dam, which was built by the US Army Corps of Engineers in the 1950s to control flooding. The river also provides water for agricultural uses, including irrigation and livestock watering. Despite its importance to the region, the Genesee River has faced challenges due to pollution and habitat degradation, leading to conservation efforts to protect the river's ecosystem.

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 Genesee River
Where does the data for the Genesee 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.
