💧 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 7.6 km away along the river. 0 report discharging now, 3 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

🌊 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.

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

Structure gauging a predominantly rural catchment with Chalk bedrock and with some artificial influences. Some flow diverted immediately u/s of station.

More detail

The catchment

Land in lower reaches is gently undulating. Predominantly Chalk. Rural catchment draining from the Chiltern escarpment.

The station

Crump profile weir (6m broad) in trapezoidal section (7.5m broad). Eel tiles and baffles added to structure in 2016. Removed from peak flows dataset in September 2023 (WINFAP Files v12).

How it measures flow

Weir subject to drowning at flows of approx. 4 cumecs. Some flow is diverted into a gravel pit through a weir (1m broad) located immediately u/s of station and infiltrates into Lower Greensand aquifer. Addition of low cost baffles and eel tiles in 2016 has minimal impact on rating. Rating does not fit well to gaugings during non-modular conditions.

Flow regime

Regime influenced by gw abstraction/recharge. Mainly industrial/agricultural abstraction. Some effluent returns.

The flow record

Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).
