You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
You'll be notified when a new storm-overflow (sewage) discharge starts within ~3 km of this gauge, based on the water companies' near-real-time feeds.
Get notified when recent rainfall near this gauge crosses its learnt rise trigger — an early "watch"
signal, typically hours before a rise. Experimental; not an official flood warning.

Flood history near this gauge
Official Environment Agency warnings issued since 2012 for the 14 flood
areas linked to this gauge (nearest 0.3 km away).
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.
See also the Deerhurst flood history.

Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Catchment Character
🌊 Mixed responseA balance of quick runoff and slower groundwater baseflow.
Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how
steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay
catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is
slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right
from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.
The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

More detail
The catchment
Very large, diverse catchment, Paleozoic slates in Welsh headwaters, Permo-Triassic sediments in middle reaches and Jurassic and Liassic clays from the Avon catchment.
The station
Cross path ultrasonic gauge to measure low to medium flows where tides affect the flow regime. Upgrade of ultrasonic gauge started June 2007. High flow and gauging site at Haw Bridge (54057) but prone to overestimate flows during tidal phases - leading to significant differences in flow series during tidal phases and dropouts in flow.
How it measures flow
Unable to infill gaps during 2011 due to ultrasonic gauge fault.
Flow regime
Substantial modification to flow owing to PWS exports and effluent returns (chiefly to the Stour, Worcester, Avon and Thames).

Frequently asked questions
Is the River Severn at Deerhurst flooding today?
The current level is 0.49m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Deerhurst?
Based on the most recent readings, the level is currently steady. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
Why is the level slowly falling?
When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.
What is a normal level for the River Severn at Deerhurst?
The typical range at this station is 0.50m to 4.49m, based on Environment Agency historical data. Levels above 4.49m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
