You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
You'll be notified when a new storm-overflow (sewage) discharge starts within ~3 km of this gauge, based on the water companies' near-real-time feeds.

River Flow
90 days
Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

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.
11 storm overflows are traced upstream of this gauge, the nearest 1.2 km away along the river. 0 report discharging now, 11 report not discharging.

1 other overflow within 6 km is downstream of this gauge or on another branch of the river network, so it is 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 →

Flood history near this gauge
Official Environment Agency warnings issued since 2007 for the 7 flood
areas linked to this gauge (nearest 1.2 km away).
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 FlashyRain runs off fast — levels rise and fall sharply, often within hours of heavy rain.
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).

Compound flume within a mill race gauging a predominantly rural catchment with London Clay covered by Boulder Clay, and with significant artificial influences.
More detail
The catchment
London Clay overlain with Boulder Clay in N. Rural, predominantly arable land with some grassland and some built-up areas in the S of the catchment.
The station
Triple throated compound flume (built within mill race). Trapezoidal centre section for low flows.
How it measures flow
Limit of station is 35 cumecs. Spillway flow starts at around 2m - very significant part of flow, allowance for this not made in record. Two peak flow rating applied across period of record.
Flow regime
Industrial and sewage effluent discharges, adjustments needed for effluent discharges.
The flow record
Naturalised flows from 1962 to 1976. Period-of-record maximum flow in Oct 2000 may have been higher due to spillway flows. Full period of record peak flow data reviewed and released in August 2024 (WINFAP Files v13).

Frequently asked questions
Is the River Can at Beach's Mill flooding today?
The current level is 0.26m, which is within the typical range of 0.14 to 1.57m. Flooding is unlikely at this level.
Is the river level rising or falling at Beach's Mill?
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.
What is a normal level for the River Can at Beach's Mill?
The typical range at this station is 0.14m to 1.57m, based on Environment Agency historical data. Levels above 1.57m are higher than usually seen and may indicate a flood risk.
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.
