Sowley Stream at Sowley Copse Track
EA name: SOWLEY STM AT SOWLEY COPSE TRACK (also listed as “SOWLEY STREAM AT SOWLEY COPSE TRACK, EAST END”)
Environment Agency sampling point SO-G0006903 · 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
- 27 Mar 2026, 14:026 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 23 Apr 2024 Imported periods: 1 Oct 2023 – 30 Sep 2026. Samples outside them are not shown here.
- Latest sample
- River / running surface water Planned investigation (local monitoring)
- Where
- National Grid 436577, 97151As published, to the nearest 1 m. Open in a map
- River, by its own name
- Sowley Stream
- River, by the map
- Not placedIts name gives Sowley Stream; the only line close by, 1 m away, is Crockford Stream and is not traced into it. The river map cannot say which watercourse this is.

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.
