⚠ The level gauge at this site, Leighton Buzzard (E21187), has been suspended by the Environment Agency since 1 Jul 2026. Flow at a gauging station is normally calculated from that level sensor, so readings here since 7 Sep 2026 may be affected.

Leighton Buzzard (E21187) — level at this site

A separate gauge 2.9 m from this one at the same site, shown here for context.
Its readings are its own and are never merged with this page's. The Environment Agency has suspended it since 1 Jul 2026.
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.
Anglian Water · into Brickhill Brook River Ouzel Nt · 5.9 km away in a straight line · its watercourse is not on the river map

4 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 2026-04), which leaves out many small channels. Explore the sewage map →
🌊 Mixed responseA 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).

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.
