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.

Flood history near this gauge
Official Environment Agency warnings issued since 2010 for the 10 flood
areas linked to this gauge (nearest 0.8 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 Loughton 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).

Ultrasonic gauging station located in the mid reaches of the River Roding catchment.
More detail
The catchment
Predominantly impermeable catchment (London clay and glacial deposits). The main land use is agriculture but the catchment contains significant urban areas.
The station
Prior to 1983, Essex weir, subject to drowning. In 1989, this was replaced by a single crest Crump weir. An ultrasonic gauge has been operating at the site since the 05/02/2012.
How it measures flow
The Crump weir had a modular limit of approx. 0.6m (no tail or downstream levels recorded). Current meter calibration of the weir, updated following gaugings taken during 2000 and 2002 floods. The ultrasonic gauge consists of 12 paths, in a cross configuration, installed in a trapezoidal concrete section just upstream of the Crump weir. The installation was commissioned for two reasons: to combat the regular occurrence of non-modular flow conditions that readily formed during high flows and secondly due to the extensive weed growth in this reach of the river that hampered measurement during low flows. Out of bank flow observed in 2024 around QMED. Not clear if station by-passed or just ponding on left bank. Full channel maintenance has not occurred since at least 2012. Channel is noticeabley more choked with reeds leading to more frequent occurrence of out of bank flow.
The flow record
No flow data from 1982-88. High flow rating under review; treat flows with caution.

Frequently asked questions
Is the River Roding at Loughton flooding today?
The current level is 0.02m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Loughton?
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 River Roding at Loughton?
The typical range at this station is 0.03m to 1.30m, based on Environment Agency historical data. Levels above 1.30m 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.
