💧 Storm overflows upstream of this gauge

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.

4 storm overflows are traced upstream of this gauge, the nearest 5.6 km away along the river. 0 report discharging now, 4 report not discharging.

Catchment Character

🌊 Mixed response A 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.

About this gauge

Crump profile gauging a Chalk catchment largely overlain with Boulder Clay and with predominantly agricultural land use, some artificial influences.

More detail

The catchment

Chalk largely overlain with Boulder Clay. Agricultural land use, predominantly arable.

The station

Crump profile weir, 4m broad. Ultrasonic flow gauge (sidelooker) installed in 2012 to measure non-modular flows more accurately.

How it measures flow

Theoretical rating confirmed by current metering to structure full, thereafter rating allows for drowning and spilling, but there is significant scatter in gaugings beyond 0.3m. One rating applied across period of record. Since 2007 there has been an increase in the frequency of occurrence of non-modular flows, and since 2013 this station has been non-modular or drowned 90% of the time. This is thought to be caused by changes in land use downstream affecting downstream water levels. An ultrasonic flow gauge was installed in 2012. In modular flow conditions flows are calculated with the conventional rating, in non-modular conditions flows are calculated from the index-velocity rating based on the measurements of the ultrasonic flow gauge.

Flow regime

Gw abstractions for PWS and industry; surface water abstractions for spray irrigation.

The flow record

Sept 1968 flooded entire area under water, maximum POR level recorded as 17.5cumecs, flow extrapolated as the river was out of bank. GDF and HIF POR updated in 2014. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).

Frequently asked questions

Is the River Thet at Redbridge flooding today?

The current level is 0.08m, which is below the typical range. Flooding is very unlikely at this level.

Is the river level rising or falling at Redbridge?

Based on the most recent readings, the level is currently rising slightly. 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 Thet at Redbridge?

The typical range at this station is 0.10m to 1.43m, based on Environment Agency historical data. Levels above 1.43m 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.
