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.
7 storm overflows are traced upstream of this gauge, the nearest 8.6 km away along the river. 0 report discharging now, 6 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

2 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 →

Flood history near this gauge
Official Environment Agency warnings issued since 2007 for the 12 flood
areas linked to this gauge (nearest 1.8 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.

🌊 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.

About this gauge
Velocity area station gauging a responsive catchment with some artificial influences.
More detail
The catchment
Responsive catchment with steep headwaters which drain complex sequence of limestones, sandstones and clays of Lower and Middle Jurassic; flat Vale of Berkeley is underlain by Cambrian inlier, Keuper Marl and Lias clays. Land-use is rural.
The station
Velocity area station replaced, in 2000, earlier gauging station which suffered from afflux from ornamental bridge upstream. New site is 10m upstream of the bridge in rectangular concrete channel; gauged from road bridge.
How it measures flow
Rating is stable for medium flows. Not great for high or low flows, high flows are influenced by flood gates downstream, which are in place to cope with the large tidal range of the River Severn and extreme events.
Flow regime
Moderate influence from public water supply abstractions and spray irrigation.
The flow record
Daily mean flow data missing from June 2002 to January 2004.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the Little Avon River at Berkeley flooding today?
The current level is 0.14m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Berkeley?
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 Little Avon River at Berkeley?
The typical range at this station is 0.15m to 1.50m, based on Environment Agency historical data. Levels above 1.50m 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.
