You'll be notified when this gauge is rising more than 0.10 mASD/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
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.

Flood history near this gauge
Official Environment Agency warnings issued since 2008 for the 13 flood
areas linked to this gauge (nearest 0.2 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.
See also the Broom flood history.
Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Catchment Character
🌊 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.
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

Crump profile weir opened in 1976 to replace Broom (54907) and provide higher containment capacity than old site.
More detail
The catchment
Low relief, predominantly agricultural catchment upon Mercia Mudstone, with small glacial gravel deposits in the eastern headwaters. Responsive; sewage effluent maintains low flows. Contains Redditch and Alcester.
The station
Opened in 1976 and replaced Broom (Old) (54907). Crump profile weir (12m) with a higher containment capacity than old site - high wing walls (1.7m) and banks.
How it measures flow
Multiple peak flow ratings applied across period of record, with upper limbs derived from gaugings. Up to 1976 rated section; not rated above bankfull when extensive inundation. In-channel weed growth prevelant immediately upstream of weir. Weed not currently managed however this is being considered for future years. Work planned in 2026-27 to carry out in-channel works. Part of the right bank has been eroded creating an Island in the centre of the river downstream of the weir, affecting the accurate recording of high river flows.
Flow regime
Sewage effluent maintains low flows. Groundwater pumping for PWS significantly augments low flow through effluent returns. Responsive catchment.
The flow record
July 2007 high flows likely to be overestimated, flows beyond capacity of measuring structure. Flows reprocessed for period 01/03/1995 to 01/01/2011 following review of rating in 2011. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9). Rating reviewed in 2022 and data reprocessed for the full period of record.

Frequently asked questions
Is the River Arrow at Broom flooding today?
The current level is 0.11m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Broom?
Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.
What is a normal level for the River Arrow at Broom?
The typical range at this station is 0.12m to 0.49m, based on Environment Agency historical data. Levels above 0.49m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
