Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Gauges connected to this river, and others nearby. A distance “by river” follows the river on the map; any other is in a straight line.
Distances by river: OS Open Rivers. Contains OS data © Crown copyright and database rights 2026.
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. Those nearby are listed below.
Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.
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 →

Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.
Flood warnings and alerts are issued for whole areas. These are the 9 areas linked to this gauge, nearest first.
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 affected by: groundwater abstraction, industrial / agricultural abstraction.

How this gauging station is built and how long it has measured (NRFA / UKCEH).
The latest recorded level is 0.17m. Compare it with the recent history on the chart above to judge whether levels are unusually high.
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.
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.
