Historical references are not flood thresholds or forecasts. This reading was received recently. It does not show whether an area is flood-safe. The Office of Public Works marked this reading as having a measurement or transmission problem. The value may be wrong.

About the levels and source data

Period comparisons use published annual peaks dated within your selection. Gaps may exist; these are not complete calendar-year or rolling-period maxima.

The highest recorded level may be revised. The median flood level is a statistical reference in the Office of Public Works dataset. Neither is the level where nearby flooding starts, and neither predicts whether flooding will happen again.

Annual records captured on Friday 28th of August 2026. Year choices list years with a published peak. OPW annual peaks refer to hydrological years; filtering their dates does not reconstruct a complete calendar-year record. Unchecked values are marked when selected.

The readings below are the highest annual water levels in the available Office of Public Works record for this station. The record contains 22 annual readings from 2004 to 2024.

Past high levels do not show when flooding starts

These are readings at this measuring station. They are not matched to flooding nearby and must not be used as flood thresholds or predictions. The Office of Public Works marks at least one of the readings below as unchecked, so it may contain errors or be revised.

Nearby flood reports

The Office of Public Works report shows recorded flood events within 2.5 kilometres of this station.

Event locations are approximate. A nearby event is not necessarily connected to this gauge. Where a same-day station reading is shown, it is context only and is not a matched flood-impact level.

Historical records are not a forecast or warning. An area can still flood even if no past event is listed.

How to read station levels

What does the metre number mean?

It is the water level measured against this station’s reference point, not the depth of the river.

Can I compare different stations?

Not directly. Stations can use different reference points.

Does a reading predict flooding?

No. A station reading is not a flood warning or an all-clear.
