Oswegatchie River river
Total streamflow across the Oswegatchie River was last observed at 1,524 cfs, and is expected to yield approximately 3,023 acre-ft of water today; about 76% of normal. Average streamflow for this time of year is 1,995 cfs, with recent peaks last observed on 2014-04-15 when daily discharge volume was observed at 16,160 cfs.
Maximum discharge along the river is currently at the Oswegatchie River Near Heuvelton Ny reporting a streamflow rate of 1,170 cfs. However, the streamgauge with the highest stage along the river is the Oswegatchie River Near Oswegatchie Ny with a gauge stage of 2.79 ft. This river is monitored from 2 different streamgauging stations along the Oswegatchie River, the highest being situated at an altitude of 1,033 ft, the Oswegatchie River Near Oswegatchie 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.

Oswegatchie River
The Oswegatchie River is a 137-mile-long river located in Northern New York that flows from the Adirondack Mountains into the St. Lawrence River. The river was historically used for transportation and logging, and its name is derived from the Mohawk word for "black water." The river's hydrology includes rapids, waterfalls, and calm stretches, making it popular for canoeing, kayaking, and fishing. There are several reservoirs and dams along the river, including the Cranberry Lake Dam and the Stillwater Reservoir. These dams provide hydroelectric power and flood control. The river is also used for agricultural purposes, such as irrigation and livestock watering. Recreationally, the Oswegatchie River is known for its camping, hiking, and hunting opportunities in the surrounding Adirondack Park.
Track the Oswegatchie 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 Oswegatchie River
Where does the data for the Oswegatchie 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.
