Quick pick:
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.

A separate gauge 0 m from this one at the same site, shown here for context.
Its readings are its own and are never merged with this page's.
Storm overflows whose water reaches this gauge on the mapped river network, nearest first by distance along the river. The status is each water company's monitor: it says whether an overflow is discharging, not how much or what it contains.
4 storm overflows are traced upstream of this gauge, the nearest 980 m away along the river. 0 report discharging now, 3 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

These are the water companies' monitor statuses; a spill does not by itself explain a change in the gauge level. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels. Explore the sewage map →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 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).

Station constructed early in 1970 at the confluence of the 2 branches of the Upper Avon adjacent to West Avon at Upavon. Benchmark station.
More detail
The catchment
Predominantly Upper Greensand and Lower Chalk; river gravel and alluvium in valley bottom. The remainder consists of Upper and Middle Chalk, Clay and some Gault. Upper Chalk and Clay form northern and extreme southern borders of catchment. Land use is predominantly pastoral and dairy farming. No major changes in catchment.
The station
Station constructed early in 1970 at the confluence of the 2 branches of the Upper Avon. Crump profile weir, crest 3.05m broad. Station adjacent to West Avon at Upavon (43017); the two weirs gauge the two branches of the Avon immediately upstream of their confluence at Upavon. Eel tiles and fish baffles installed in 2015.
How it measures flow
Full range station, some limited bypassing but there has been no validation. Weed growth not significant. Suspicion of small errors within the stilling well caused by increased buoyancy of the counter weight when submerged - may cause small errors in stage measurement in the order of a few mm's only. No by-passing but adjacent pond was flooded (although not entering downstream channel). Theoretical, original rating applies; very few spot gaugings available. Upper limit of rating is 0.73m / 4.23 m3/s. It is extrapolated beyond that limit.
Flow regime
Natural to within 10% at Q95. Benchmark catchment but agricultural abstractions increasing. Occasional upstream hatch action.
The flow record
18/01/2011 - at a level of 0.728 the modularity was observed at 60.6%. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Avon at Upavon West flooding today?
The current level is 0.05m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Upavon West?
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.
What is a normal level for the River Avon at Upavon West?
The typical range at this station is 0.06m to 0.70m, based on Environment Agency historical data. Levels above 0.70m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
