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.

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.
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.

None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.
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 →

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.

How it measures flow
Modular limit of 0.66m theoretically derived; secondary instrument to record non-modular flows installed in 2003. Lack of gaugings at high flows. One rating applied across period of record.
Flow regime
Natural to within 10% at Q95.
The flow record
No POT data are presented for this station as they have no non-modular flow correction applied. AMAX data have been corrected, but in some cases can be below the daily flow as these are not corrected. Naturalised flows from 1969 to 1976, only minimal adjustments needed since. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Brett at Cockfield flooding today?
The current level is 0.02m, which is within the typical range of 0.02 to 0.75m. Flooding is unlikely at this level.
Is the river level rising or falling at Cockfield?
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 Brett at Cockfield?
The typical range at this station is 0.02m to 0.75m, based on Environment Agency historical data. Levels above 0.75m 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.
