None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow. Those nearby are listed below.
Nearby, connection not known
Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.
Anglian Water · into Tributary Of The River Ouzel · 5.8 km away in a straight line · its watercourse is not on the river map

5 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 →
🌊 Fairly flashyResponds 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.

A triangular Flat V weir gauging a predominantly rural, Greensand catchment with some artificial influences. Multiple structures in operation during POR.
More detail
The catchment
Greensand catchment, tributary to the river Ouzel. Predominantly rural, minor urban development (Leighton Buzzard).
The station
A triangular Flat V weir installed in 2002, 1km u/s of the previous structures: Crump weir (1966-1980) broad-crested weir (1957-1962).
How it measures flow
Current daily flow rating considers drowning although there are limited gaugings to confirm rating. Two peak flow ratings applied across period of record, the most recent is valid from Oct 2002 when the new weir was constructed.
Flow regime
Runoff influenced by groundwater abstraction/recharge. Runoff reduced by industrial/agricultural abstraction. Runoff augmented by effluent returns.
The flow record
Peak flow data are only presented for the current structure (01/10/2006 onwards). Gap in record when station not operational (1980-2002). Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).

Frequently asked questions
Is CLIPSTONE BROOK GS LEIGHTON BUZZARD WITS DO NOT POLL MANUALLY flooding today?
The latest recorded level is 0.02m. Compare it with the recent history on the chart above to judge whether levels are unusually high.
Is the river level rising or falling at CLIPSTONE BROOK GS LEIGHTON BUZZARD WITS DO NOT POLL MANUALLY?
Based on the most recent readings, the level is currently steady. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
How often is this river level data updated?
Readings are supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
