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.

Cohansey River
The Cohansey River is a 30-mile long river in southern New Jersey that flows through Cumberland County before emptying into the Delaware Bay. The river has a rich history, having played a vital role in the development of the area's agricultural and industrial sectors. The river is fed by several tributaries, including the Manantico Creek and the Maurice River. There are several reservoirs and dams along the river, including the Dividing Creek Dam and the Maskell's Mill Dam. These dams are used for flood control and to provide water for agricultural irrigation. The Cohansey River is also popular for recreational activities such as fishing, boating, and birdwatching. The river is home to a variety of fish species, including striped bass, bluefish, and white perch. The river is also surrounded by farmland, with crops such as corn, soybeans, and wheat being grown in the area.

Track the Cohansey 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 Cohansey River
Where does the data for the Cohansey 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.
