Whippany River river
Total streamflow across the Whippany River was last observed at 81 cfs, and is expected to yield approximately 160 acre-ft of water today; about 37% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 216 cfs, with recent peaks last observed on 2021-09-02 when daily discharge volume was observed at 3,410 cfs.
Maximum discharge along the river is currently at the Whippany River Near Pine Brook Nj reporting a streamflow rate of 45.5 cfs. This is also the highest stage along the Whippany River, with a gauge stage of 2.74 ft at this location. This river is monitored from 3 different streamgauging stations along the Whippany River, the highest being situated at an altitude of 314 ft, the Whippany River Near Morristown Nj.

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.

Whippany River
The Whippany River is a 17.7-mile-long river located in Morris County, New Jersey. The river was once a vital source of power for local industries, including mills and factories. It has been designated a Category One trout production stream due to its excellent water quality and cold-water fishery. The river's headwaters begin in Mendham and it flows through several towns, including Morristown and Hanover. The river is home to several reservoirs and dams, including the Boonton Reservoir and the Lake Parsippany Dam. These reservoirs serve as sources of drinking water for local communities. The river is used for recreational activities like fishing, kayaking, and hiking, and is an important water source for agricultural irrigation.

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