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.

Nimbus beta
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.

Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Nearby Stations
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.
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.
62 storm overflows are traced upstream of this gauge, the nearest 4.8 km away along the river. 0 report discharging now, 59 report not discharging, and for 3 the monitor is offline or has not reported, so their status is not known.

8 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 2012 for the 15 flood
areas linked to this gauge (nearest 0.7 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.

Timing, not cause. Gauges can move together simply because the same rain fell on both.
