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.

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.
37 storm overflows are traced upstream of this gauge, the nearest 440 m away along the river. 0 report discharging now, 30 report not discharging, and for 7 the monitor is offline or has not reported, so their status is not known.

2 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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 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).

A non-standard Essex profile Flat V weir based in the Roding catchment with rural headwaters but influenced by urban development in the lower reaches. The flow regime has artificial influences.
More detail
The catchment
Low lying, mainly impervious (London Clay and superficial deposits) catchment. Land use is rural with significant urban development close to the G/s.
The station
Originally a broad crested weir but was replaced due to insensitivity at low flows. Replaced by the current Essex profile weir (modified Flat V weir) in 1962. Used for both flood warning/forecasting and water resource purposes.
How it measures flow
One peak flow rating applied across period of record. Rating may not estimate flow accurately above 1m. Calibration above 35 cumecs is based upon model tests.
Flow regime
Pattern of low flows influenced by abstractions and effluent returns. Flows augmented by moderate net import of water from Thames Water Utilities but this was eliminated to produce naturalised flows between 1951-1975. The diversion of Luxborough Lane STW effluent, completed in 1987, reduced DMFs in Redbridge.
The flow record
Significant floods in Nov 1974 and Oct 2000. Questions whether gauge drowned during these events. Full period of record peak flow data reviewed and released in September 2022 (WINFAP Files v11).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Roding at Redbridge flooding today?
The current level is 0.12m, which is within the typical range of 0.12 to 1.44m. Flooding is unlikely at this level.
Is the river level rising or falling at Redbridge?
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 Roding at Redbridge?
The typical range at this station is 0.12m to 1.44m, based on Environment Agency historical data. Levels above 1.44m 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.
