You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.

Each one is saved as its own alert — pause or remove them individually any time.

Not an emergency service — if in danger call 999. Alerts rely on EA/SEPA/NRW data and are best-efforts. Terms

💧 Storm overflows upstream of this gauge

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.

134 storm overflows are traced upstream of this gauge, the nearest 29.2 km away along the river. 1 reports discharging now, 122 report not discharging, and for 11 the monitor is offline or has not reported, so their status is not known.

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 →
