💧 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 580 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).
