Active weather warnings for New Jersey
Flash Flood Warnings remain in effect across New Jersey as severe thunderstorms continue to impact the state. Monmouth and Ocean Counties face immediate threats with up to 3 inches of rainfall reported; NJ Route 35 in Belmar and NJ Route 71 are closed due to flooding, with stranded vehicles reported. Residents in Long Branch, Asbury Park, Toms River, and Jackson should exercise extreme caution and avoid flooded roadways. In Gloucester County, Route 42 near Williamstown is also closed. Communities including Cherry Hill, Mount Laurel, and Lakewood are at high risk for urban flooding and stream overflow. Warnings remain active until 11:00 AM EST. Turn around if encountering flood waters; do not attempt to cross inundated roads.
How New Jersey’s rivers compare to normal
Every gauge placed by its own percent of normal, and three years of the statewide trend.
Where every gauge actually sits
One dot per New Jersey streamgauge, placed by its own percent of normal. The state average is a single line through all of it.
Percent of normal compares today's discharge with the historical average for this calendar day. Tap any dot to open that gauge.
New Jersey streamflow, three water years
Statewide percent of normal, every day since Nov 2023. The dotted line is normal.
799 daily readings from 96 reporting gauges. Percent of normal is today's statewide discharge against the historical average for the same calendar day — 100% is normal, not "good". The axis tops out at 250%: 38 readings above that — including the 732% peak in Dec 2023 — are drawn along the top edge, so a few flood days cannot flatten three years of everything else. The line breaks in 2 places where the record skips more than five days — those are gaps in reporting, not readings of zero.

About New Jersey streamflow
What are river levels like in New Jersey right now?
As of November 6, 2026, New Jersey rivers are running at 52% of normal across 96 USGS streamgauges, and the Delaware River At Trenton Nj is reporting the highest discharge at 3,370 cfs. The full sortable gauge table is below.
Which New Jersey river is running highest right now?
As of November 6, 2026, the highest discharge in New Jersey is 3,370 cfs on the Delaware River At Trenton Nj. See the sortable gauge table for the full statewide ranking.
Are New Jersey rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means New Jersey rivers are running higher than the seasonal average for the date, below 100% means lower (a dry spell or drought). Each gauge also shows its own percent of median.
Where does the New Jersey streamflow data come from?
The U.S. Geological Survey National Water Information System. USGS streamgauges report continuously (every 15 minutes) and the data is the canonical real-time record for U.S. rivers. Snoflo pulls the latest readings and joins them to a 7-day NOAA weather forecast for each station.
What is cfs?
Cubic feet per second — the standard unit for streamflow. One cfs is about 7.5 gallons per second. Small creeks run at single-digit cfs; the Mississippi at hundreds of thousands.
What does Gauge Height mean?
The water level at the gauge in feet above the reference datum. Used together with discharge to track river state. Flood stage and runnable levels are typically expressed in gauge height (e.g., "flood at 16 ft").
How fresh is the New Jersey data?
USGS streamgauges report every 15 minutes; Snoflo re-pulls throughout the day. The AI briefing regenerates daily.
Can I get a flow alert for a New Jersey gauge?
Yes. Save any USGS gauge as a favorite in the Snoflo iOS app, set a discharge or stage threshold (e.g. "alert me when discharge crosses 2,000 cfs"), and you'll get a push the moment it crosses.
Is this a substitute for an NWS flood warning?
No. Snoflo is informational. For flood life-safety decisions always follow guidance from your local NWS forecast office and state emergency management. Snoflo data is one input among several.
