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.

Nimbus beta
Experimental model fusing soil moisture, river flow, groundwater and catchment

River Flow

Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

Flood history near this gauge
Official Environment Agency warnings issued since 2011 for the 8 flood
areas linked to this gauge (nearest 4.1 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.

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).

More detail
The catchment
Predominantly permeable (Chalk) catchment with a small inlier of Upper Greensand and Gault. The northern area of the catchment consists of a band of Greensand between bands of lower chalk. The rest of the catchment is composed of upper Chalk. Land use is rural. Topographical and groundwater catchments do not coincide. No major changes.
The station
Crump profile weir (crest 9.14m wide) flanked by broad-crested weirs.
How it measures flow
Full range station, a good gauge for high flow analysis .No known out of bank bypassing. Observed to be fully modular at 0.986m. Small bypass channel approx. 2m u/s of weir - included in rating. Weed growth downstream of the weir has in very exceptional summers been known to cause non-modularity. Two peak flow ratings applied across period of record. Re-rated in 2001 to include exceptional 12/2000 event and applied to whole period of record. The EA are very confident of the stage-discharge relationship. Good high flow rating based on current meter gaugings. Upper limit of rating is 1m / 26.3 cumecs. It is extrapolated beyond that limit.
Flow regime
Some groundwater pumping influences flows. During summer, flows are naturally augmented from groundwater draining from northern half of the River Bourne catchment.
The flow record
Peak flows prior to 1987 are truncated and therefore rejected. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).

Frequently asked questions
Is the River Avon at Amesbury flooding today?
The current level is 0.14m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Amesbury?
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 Amesbury?
The typical range at this station is 0.15m 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 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.
