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.

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.

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.
See also the Berkeley 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
🌊 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.
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).

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.

Frequently asked questions
Is the Little Avon River at Berkeley flooding today?
The current level is 0.15m, which is within the typical range of 0.15 to 1.50m. Flooding is 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 7 days of measurements, 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 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.
