Manasquan River river
Total streamflow across the Manasquan River was last observed at 59 cfs, and is expected to yield approximately 117 acre-ft of water today; about 40% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 149 cfs, with recent peaks last observed on 2017-05-06 when daily discharge volume was observed at 4,070 cfs.
Maximum discharge along the river is currently at the Manasquan River At Squankum Nj reporting a streamflow rate of 31.8 cfs. However, the streamgauge with the highest stage along the river is the Manasquan R Nr Allenwood Nj with a gauge stage of 7.51 ft. This river is monitored from 2 different streamgauging stations along the Manasquan River, the highest being situated at an altitude of 51 ft, the Manasquan R Nr Allenwood 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.

Manasquan River
The Manasquan River is a 26-mile-long river that runs through central New Jersey, flowing into the Atlantic Ocean. The river's hydrology has been altered over time due to human activity, including the construction of reservoirs and dams. The most notable of these are the Manasquan Reservoir and the Manasquan Dam, which were built in the early 20th century to provide a reliable source of drinking water for the city of Newark. Today, the river is used for recreational activities like fishing, boating, and kayaking, and is also an important source of irrigation for local agricultural operations. Despite some environmental concerns related to pollution and habitat destruction, efforts are being made to preserve and restore the Manasquan River ecosystem.

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