💧 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.

3 storm overflows are traced upstream of this gauge, the nearest 570 m away along the river. 0 report discharging now, 2 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

1 other overflow within 6 km is downstream of this gauge or on another branch of the river network, so it is 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.

About this gauge

'Essex' profile gauging a small, rural, virtually natural catchment.

More detail

The catchment

Chalk and glacial gravel in the catchment completely overlain with Boulder Clay. Rural, predominantly arable land.

The station

'Essex' profile (modified Flat V Crump) weir with crest tapping and high flow spillway.

How it measures flow

Modular limit approx. 6.0 cumecs. Approx. limit of gauging is 12.5 cumecs. Bypassing estimated to start at 1.2m. Rating accounts for non-modular flow above 6 cumecs. One rating applied across period of record.

Flow regime

Some industrial/agricultural abstraction, but natural to within 10% at Q95. Only minor adjustments needed, virtually natural catchment.

The flow record

No POT data are presented for this station as they have no non-modular flow correction applied. AMAX data have been corrected, but in some cases can be below the daily flow as these are not corrected. Highest gauging taken in 1968 and is an estimate. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).

Frequently asked questions

Is the Bumpstead Brook at Broad Green flooding today?

The current level is 0.04m, which is within the typical range of 0.02 to 1.11m. Flooding is unlikely at this level.

Is the river level rising or falling at Broad Green?

Based on the most recent readings, the level is currently falling slightly. 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. 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.

What is a normal level for the Bumpstead Brook at Broad Green?

The typical range at this station is 0.02m to 1.11m, based on Environment Agency historical data. Levels above 1.11m 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.
