💧 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.

18 storm overflows are traced upstream of this gauge, the nearest 2.3 km away along the river. 0 report discharging now, 18 report not discharging.

6 more within 6 km whose connection is not known.

3 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 2026-10), which leaves out many small channels. Sewage & storm overflows →

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

Velocity-area station opened in 1962 and rebuilt after 1968 flood, weir built in 1971.

More detail

The catchment

Rises in Greensand and Gault Clay of the Blackdown Hills. Predominantly Keuper sandstones and marls. Extensive alluvium and valley gravels lower down. Some heathland, woodland and pasture, and a wide range of agriculture. No major catchment changes.

The station

Velocity area station with cableway. Station opened in 10/1962. Hut rebuilt after July 1968 flood. 14m wide informal shallow Flat V weir installed 1971. Initially for Water Resources, more recently considered full range with FCRM interest.

How it measures flow

Natural control up until weir installed in 1971. Now considered a full range station. Low embankments at field level extend containment. Gabions stabilise bed and banks. Bypassing occurs during exceptional events (>2.1m). Multiple ratings applied across period of record; high flow events in Nov/Dec 2000 altered channel geometry u/s and d/s of station. Ratings after this period include estimates for out of bank flow.

Flow regime

Substantial groundwater and surface water abstractions in catchment for public water supply and industrial/agricultural purposes. Flows increased by effluent returns.

The flow record

Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).
