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

Alert me when (tick one or more)
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.

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.
60 storm overflows are traced upstream of this gauge, the nearest 4.2 km away along the river. 0 report discharging now, 59 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

2 more within 6 km whose connection 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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

Is the Christchurch Coast at Christchurch flooding today?
The latest recorded level is -0.18m. Compare it with the recent history on the chart above to judge whether levels are unusually high.
Is the river level rising or falling at Christchurch?
Based on the most recent readings, the level is currently rising. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
Why is the level slowly falling?
When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.
How often is this river level data updated?
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.
