Official Environment Agency warnings issued since 2020 for the 2 flood areas linked to this gauge (nearest 6.5 km away).
Most recent flood warning: 22 Feb 2024 — River Nar at Narborough, Marham, Wormegay and Saddle Bow
| Year | Warnings | Alerts |
|---|---|---|
| 2024 | 3 | 0 |
| 2020 | 1 | 0 |
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record. See also the Marham flood history.

Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.
The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).
Flow affected by: public water supply, groundwater abstraction, effluent returns, industrial / agricultural abstraction.

How this gauging station is built and how long it has measured (NRFA / UKCEH).
The current level is 0.10m, which is below the typical range. Flooding is very unlikely at this level.
Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.
The typical range at this station is 0.10m to 0.32m, based on Environment Agency historical data. Levels above 0.32m are higher than usually seen and may indicate a flood risk.
Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
