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.

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.

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.
20 storm overflows are traced upstream of this gauge, the nearest 2.1 km away along the river. 0 report discharging now, 20 report not discharging.

3 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are not listed.
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 →

Flood history near this gauge
Official Environment Agency warnings issued since 2006 for the 6 flood
areas linked to this gauge (nearest 1.2 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.

🌊 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.

More detail
The catchment
Rises in the Blackdown Hills. Headwaters drain Greensand and Gault Clay. Predominantly Permo-Triassic sandstones, breccias and marls with extensive valley gravels and alluvium. The catchment has a subdued relief and is predominantly agricultural; the largest settlement is Cullompton. Small areas of woodlands in the east. No major catchment changes.
The station
Originally a velocity-area station with a cableway, reliable records began in 1962. The river was regraded and downstream obstructions were removed in August 1965. Station rebuilt between 1971 and 1973, and during this period a temporary recorder was installed downstream. New weir fully operative from 08/1973 - an informal shallow V weir, 11.45 m overall width, 1:26 side slopes, 1:18 u/s and d/s slopes.
How it measures flow
Weir acts as a low flow control, with channel control when structure is drowned. Full range. Widespread upstream inundation during floods. Multiple peak flow ratings across period of record. Ratings extended to include modelled out-of-bank flows. Bypassing probably occurs at about 2 m, u/s on the left bank, and the station is likely to be outflanked at any stage greater than 2.3 m. Shoal development has led to a number of ratings across period of record, with different low flow limbs. High flow limbs very similar, so simplified rating record applied to data. Current rating uses hydraulic modelling to extend beyond gauged range. Some out of bank gaugings help validate rating. Ratings for velocity-area station derived from gaugings, with some slope-area estimates above bankfull. Upper segment of rating for the temporary recorder 1971-73 derived by correlation between the sites.
Flow regime
Runoff reduced by public water supply abstraction. Runoff influenced by groundwater abstraction/recharge. Runoff increased by effluent returns. Runoff reduced by industrial/agricultural abstraction. Moderate surface and groundwater abstractions affect low flows.
The flow record
Shoaling on structure may affect flows from 1998 until river bed re-profiling in 2008, despite rating adjustments. Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).

Frequently asked questions
Is the River Culm at Woodmill flooding today?
The current level is 0.24m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Woodmill?
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 Culm at Woodmill?
The typical range at this station is 0.25m to 1.60m, based on Environment Agency historical data. Levels above 1.60m 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.
