You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
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.

Flood history near this gauge
Official Environment Agency warnings issued since 2011 for the 7 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 Wilton 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
🌊 Groundwater-fedSlow and steady — fed largely by groundwater, so levels change gradually, not in sudden spikes.
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).

Photos

Mixed geological formation (Jurassic and Cretaceous) - predominantly Chalk with Clays in upper catchment. Land use is rural. No major catchment changes.
The station
Crump weir, crest 18.3m wide.
How it measures flow
Crest tapping abandoned after first few months; modular limit (0.6m) seldom reached, although weir can drown at very high flows. Bypassing is minor. Banks very weedy during summer. Rare weed clearance can lead to significant u/s constriction. Minor bypass. Gaugings taken 50-100m upstream, previously taken at Bull Bridge. Single theoretical rating has been confirmed by spot gaugings at high and low flows. Rating may underestimate in mid flow range. Upper limit of rating is 0.48m/12.8cumecs. It is extrapolated beyond that limit.
Flow regime
Natural to within 10% at Q95; some minor groundwater pumping. Sluices and hatches can regulate flow for short periods. A small drainage channel bypasses the recorder.

Frequently asked questions
Is the River Nadder at Wilton flooding today?
The current level is 0.09m, which is within the typical range of 0.09 to 0.57m. Flooding is unlikely at this level.
Is the river level rising or falling at Wilton?
Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.
What is a normal level for the River Nadder at Wilton?
The typical range at this station is 0.09m to 0.57m, based on Environment Agency historical data. Levels above 0.57m 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.
