Quick pick:
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.

Nimbus beta
Experimental model fusing soil moisture, river flow, groundwater and catchment
character. The shaded band is its 10–90% range, widened so that about 80% of recent outcomes fall inside it.
Under evaluation — not yet promoted, so treat as a second opinion. The nearest rain gauge has sent no readings in the last day, so Nimbus has no recent measured rain to work from here.
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.
2 storm overflows are traced upstream of this gauge, the nearest 2.0 km away along the river. 0 report discharging now, 2 report not discharging.

8 more within 6 km whose connection is not known.
13 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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 Urban & flashyHeavily built-up — rain runs off hard surfaces fast, so levels can spike 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).

Flow-Duration Curve
Daily flow (m³/s) exceeded each % of the time — a steep curve is flashy, a flat one is steady. Q5 high · Q50 median · Q95 low.
A narrow catchment; Chalk headwaters but a largely London Clay catchment of urban/suburban character. Topographic catchment slightly exceeds effective drainage area.
The station
Trapezoidal flume from November 1939, with nominal capacity 26.7m/3s but no standing-wave formed until invert raised in 1961. Overall channel width: 10m. Original station built 1935 as a flume: details unknown, but thought to have had maximum capacity of around 6.2m3/s.
How it measures flow
Capacities of u/s and d/s culverts can influence flood flows. One peak flow rating applied across period of record. Gaugings confirm rating to ~1.7m with some scatter evident. Highest gauging c0.7 QMED. Ongoing gauging programme to verify rating (which overestimates flows).
Flow regime
Artificial flow pattern; runoff augmented by sewage effluent which has increased over the record. Runoff influenced by groundwater abstraction/recharge.
The flow record
Very patchy flow record prior to 1983. Bypassed during flood of September 1968; peak estimated at 24-34 cumecs. Full period of record peak flow data reviewed and released in August 2024 (WINFAP Files v13).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the Beverley Brook at Wimbledon Common flooding today?
The current level is 0.19m, which is within the typical range of 0.10 to 1.61m. Flooding is unlikely at this level.
Is the river level rising or falling at Wimbledon Common?
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 Beverley Brook at Wimbledon Common?
The typical range at this station is 0.10m to 1.61m, based on Environment Agency historical data. Levels above 1.61m 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.
