Quick pick:
You'll be notified when this gauge is rising more than 0.10 mASD/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.
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 2008 for the 12 flood
areas linked to this gauge (nearest 2.0 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 Aldington 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
🌊 FlashyRain runs off fast — levels rise and fall sharply, often within hours of heavy rain.
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).

Flat V weir in straightened cut with cableway replacing original trapezoidal flume (1968-95) that suffered from weed growth and poor state of repair.
More detail
The catchment
River rises from springs on Cotswolds scarp; steep headwaters. Drift free, mostly Liassic argillaceous rocks. Agriculture and horticulture dominate.
The station
Original trapezoidal flume (1968-95) replaced in 1995 (poor state of repair and weed growth problems affecting low flows). New weir is a flat V Crump profile (1:10) weir in straightened cut 5m wide, with wing walls at 0.7m and has cableway. Fish baffles added to weir in June 2018.
How it measures flow
Cableway rated with flood banks containing all but the highest flows but inundation occurs u/s. Flat V weir drowns at medium levels but rating fits gaugings well below 2m stage. Constriction upstream will increase approach velocity. Original trapezoidal flume rating supported by c/m gaugings but poor state of repair and weed growth problems affecting low flows. Two ratings applied across period of record, the most recent is valid from July 1995 when flume replaced.
Flow regime
PWS from headwater springs; river abstractions for horticulture. Sewage works short way upstream. Net result moderate, significant at low flows.
The flow record
Station closed between Dec 1994 and July 1995. Flows in June 2018 affected by fish baffle construction on weir. April 1998 flood at 3.14m, estimated as 100 cumecs, well above rating limit so considerable uncertainty in this magnitude. July 2007 flood 0.5m above April 1998. Such flows are outside design range of site and degree of rating extrapolation means peak flows are considered inaccurate. Full period of record peak flow data reviewed and released in September 2022 (WINFAP Files v11).

Frequently asked questions
Is the Badsey Brook at Offenham flooding today?
The current level is 0.09m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Offenham?
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 Badsey Brook at Offenham?
The typical range at this station is 0.14m to 1.11m, based on Environment Agency historical data. Levels above 1.11m 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.
