Padbury Brook tributary of Ouse Road Bridge upstream of Hethe
EA name: PADBURY BK.TRIB.OUSE RD.BR. U/S HETHE
Environment Agency sampling point AN-02M04 · Freshwater - rivers · listed as open (“open” does not mean it is sampled now)
These are samples taken on a date, not live readings of the river. Results reach the Environment Agency's archive days to months after the sample is taken, so the newest here may be weeks or months old. FloodRadar does not grade them.
Where and when
- Last sampled
- 22 May 2026, 11:534 months ago · time as the Environment Agency records it (UK clock time; the source gives no time zone). Not sampled since, as far as the archive shows: the Environment Agency was asked up to 30 Sep 2026 and had nothing newer.
- Samples banked
- 26 since 25 Jun 2024 Imported periods: 1 Oct 2023 – 30 Sep 2026. Samples outside them are not shown here.
- Latest sample
- River / running surface water Monitoring (national agency policy)
- Where
- National Grid 459500, 229600As published, to the nearest 100 m (so up to about 70 m out). Open in a map
- River, by its own name
- Padbury Brook Tributary Ouse Rd Br
- River, by the map
- Not placedGrid reference only to 100 m and no line carries the name it gives, so position alone cannot choose. The river map cannot say which watercourse this is.
- Next gauge downstream

FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
