EA forecast (official)
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.
194 storm overflows are traced upstream of this gauge, the nearest 12.2 km away along the river. 1 reports discharging now, 181 report not discharging, and for 12 the monitor is offline or has not reported, so their status is not known.
Thames Water · into R.thames ( Tidal ) · 1.6 km away in a straight line · discharges to the sea, an estuary or tidal water
0 spills · 0 hours in 2025
Not discharging now · last
33 more within 6 km whose connection 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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.
