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.

Rockaway River
The Rockaway River is a 35-mile-long river that flows through Morris County, New Jersey. It was used by Native Americans for fishing and transportation prior to European settlement. The river has a drainage area of 129 square miles and is fed by numerous tributaries. The river is heavily regulated by four major reservoirs and dams: Boonton Reservoir, Jersey City Reservoir No. 3, Splitrock Reservoir, and Lake Hopatcong. The largest of these is Lake Hopatcong, which was created by the Morris Canal and completed in 1831. The Rockaway River is a popular destination for recreational activities such as hiking, fishing, and kayaking, and it also provides water for agriculture and drinking water for municipalities in New Jersey.

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