💧 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.

10 storm overflows are traced upstream of this gauge, the nearest 1.6 km away along the river. 0 report discharging now, 9 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

4 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 →

Catchment Character

🌊 Fairly flashy Responds 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.

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).

About this gauge

Compound broad-crested weir gauging a predominantly Chalk catchment. Station has record length over 50 years.

More detail

The catchment

Predominantly Chalk overlain with 50% Boulder Clay. Agricultural land use.

The station

Compound broad-crested trapezoidal weir, 7.6m broad; central notch, 2.7m broad.

How it measures flow

The weir is subject to drowning at high flows with some bypassing on the left bank; further gaugings required to confirm extent of this. Theoretical rating since Aug 1970. Previously, rating derived using a hydraulic model. Full EA rating developed in 2012 combining existing EA rating for first 3 segments, regression through check gaugings for segments 4 and 5, and an EA modelled high flow rating used for the top segment. New rating applied to length of record.

Flow regime

Runoff increased by effluent returns and reduced by industrial/agricultural abstraction.

The flow record

Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).

Frequently asked questions

Is CAPPENHAM GS flooding today?

The latest recorded level is 0.21m. Compare it with the recent history on the chart above to judge whether levels are unusually high.

Is the river level rising or falling at CAPPENHAM GS?

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.

Why is the level slowly falling?

When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. Only about 0.0mm of rain has fallen nearby in the last 7 days, so the flow is being sustained mainly by groundwater. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.

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.
