This gauge is tidally influenced — levels rise and fall with each tide, so rapid changes here
are normal and don't necessarily indicate flooding.

Flood predictions aren't generated for
tidal gauges —
their levels are driven by the tide,
not by catchment rainfall, so the forecast models would have no skill here.
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.
28 storm overflows are traced upstream of this gauge, the nearest 12.6 km away along the river. 0 report discharging now, 27 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

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 →

Counted from each day's highest reading. Days with missing or implausible readings are left out, so a year marked patchy may have run high more often than shown.
The darker part is days above 3.72 m, the level this gauge tops only a few days a year.
