West Fen Drain adjacent Newham Drain
EA name: WEST FEN DRAIN ADJACENT NEWHAM DRAIN (also listed as “RSN2160 WEST FEN DRAIN ADJACENT NEWHAM DRAIN”)
Environment Agency sampling point AN-RSN2160 · 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
- 3 Dec 2025, 11:3110 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
- 24 since 8 Jan 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 528023, 352713As published, to the nearest 1 m. Open in a map
- River, by its own name
- Its name does not give one
- River, by the map
- Howbridge DrainPlaced by position alone, on a line whose map name differs from its own, 5 m from the line.
- Next gauge downstream
- None tracedIts water reaches the sea without passing a gauge.
- Why it was sampled

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.
