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.

River Flow
90 days
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.
2 storm overflows are traced upstream of this gauge, the nearest 2.7 km away along the river. 0 report discharging now, 2 report not discharging.

8 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 7 flood
areas linked to this gauge (nearest 0.2 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.

🌊 Fairly flashyResponds fairly quickly to rain, with moderate baseflow between events.
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
Responsive, predominantly natural catchment of moderate relief draining eastwards from coastal hills and drains upland north of Bodmin Moor. Geology mainly comprises of Devonian shales and grits and Carboniferous Culm Measures. Land use is rural, grazing and low grade agriculture with minor forestry.
The station
Velocity area station with informal Flat V low flow wooden control 16.9m wide (surveyed in 2005). Good straight approach. 36.5m span cableway extends over flood banks.
How it measures flow
Insensitive at low flows given wide section. Reaches bankfull on left bank in larger floods and then bypassed on right bank. Rating developed using gaugings, to be reviewed due to bias and gauging deviation. Peak event flow December 1979 estimated at 3.234m using Mannings following wrack mark survey and used as a gauging in derivation of peak flow rating. Two peak flow ratings across period of record.
Flow regime
Sensibly natural although runoff influenced by gw abstraction/recharge and some effluent returns. No major changes to catchment.
The flow record
Station closed from 1981 to 1985, no data available. Data suspect pre-1972, historical evidence suggests levels backed up so flows over-estimated and peak flows are rejected for this period. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Ottery at Werrington flooding today?
The current level is 0.12m, which is within the typical range of 0.10 to 1.40m. Flooding is unlikely at this level.
Is the river level rising or falling at Werrington?
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 Ottery at Werrington?
The typical range at this station is 0.10m to 1.40m, based on Environment Agency historical data. Levels above 1.40m 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.
