Upstream of Foulden sewage treatment works - Foulden Stream
EA name: U/S FOULDEN STW - FOULDEN STREAM
Environment Agency sampling point AN-SSN1479 · 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
- 9 Dec 2024, 15:2222 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 8 Oct 2026 and had nothing newer.
- Samples banked
- 14 since 10 Jan 2024 Imported periods: 1 Oct 2023 – 8 Oct 2026. Samples outside them are not shown here.
- Latest sample
- River / running surface water Monitoring (national agency policy)
- Where
- National Grid 575734, 299022As 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
- An unnamed streamPlaced by position alone (the only river line close by), 8 m from the line.
- Next gauge downstream
- Wissey Sluice On the River Wissey · 7.4 km along the river (the path rests on a repair to the map)

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.
