💧 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 11.7 km away along the river. 0 report discharging now, 4 report not discharging.

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 rural, Upper Chalk semi-pervious catchment with some artificial influences.

More detail

The catchment

Upper Chalk largely covered mainly with semi-pervious Boulder Clay and some sands and gravels. Predominantly rural catchment, mainly arable land.

The station

'Essex' profile (modified Flat V Crump) weir with low flow side weir and high flow rated spillway. D/s water level recorder to allow for drowning. Station removed from peak flows dataset in August 2024 (WINFAP Files v13).

How it measures flow

Drowning compensated for using d/s water level recorder. Rating potentially overestimates flows below 0.6m but this is slight. One rating applied across period of record.

Flow regime

Gw-influenced regime. Since 1976, adjustments for gw abstractions for PWS and industrial abstraction from surface water are no longer made to the gauged daily mean flows. Minor effluent returns may affect flow.

The flow record

No peak flow data are presented for this station as uncertainty related to non-modularity mean there is limited confidence in high flows. Naturalised flows from 1962 to 1976. Since 1976, adjustments for gw abstractions no longer made to the DMFs.
