Active weather warnings for Delaware
Delaware residents in Inland Sussex and Delaware Beaches are under a Coastal Flood Advisory until midnight EDT tonight, October 24th. The National Weather Service warns of up to half a foot of inundation above ground level in low-lying areas near shorelines and tidal waterways. Elevated water levels and minor coastal flooding will continue through this evening, particularly affecting back bay areas. Vulnerable roads in coastal and bayside communities may experience partial or full closures. Residents should avoid travel in affected areas and exercise caution near waterways during this period.
How Delaware’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 Delaware 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.
Delaware streamflow, three water years
Statewide percent of normal, every day since Oct 2023. The dotted line is normal.
799 daily readings from 15 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%: 32 readings above that — including the 1450% peak in Oct 2026 — 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.

As of October 23, 2026, Delaware rivers are running at 111% of normal across 15 USGS streamgauges, and the Brandywine Creek At Wilmington is reporting the highest discharge at 238 cfs. The full sortable gauge table is below.
Which Delaware river is running highest right now?
As of October 23, 2026, the highest discharge in Delaware is 238 cfs on the Brandywine Creek At Wilmington. See the sortable gauge table for the full statewide ranking.
Are Delaware rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Delaware 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 Delaware 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 Delaware 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 Delaware 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.
