West Fleet Stream
EA name: WEST FLEET STREAM (also listed as “WEST FLEET STREAM AT FOOTBRIDGE”)
Environment Agency sampling point SW-50040405 · 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
- 7 Sep 2026, 09:4924 days ago · time as the Environment Agency records it (UK clock time; the source gives no time zone)
- Samples banked
- 27 since 13 Jun 2024 Imported periods: 1 Oct 2023 – 30 Sep 2026. Samples outside them are not shown here.

- River / running surface water Planned investigation (local monitoring)
- Where
- National Grid 361845, 80456As published, to the nearest 1 m. Open in a map
- River, by its own name
- West Fleet Stream
- River, by the map
- West FleetPlaced on a river whose name partly matches its own, 197 m from the line. A tidal reach: water runs both ways, so no gauge order is claimed.
- Next gauge downstream
- Not known
- Why it was sampled
- Planned investigation (local monitoring) (18 samples)
Monitoring (national agency policy) (9 samples)
12 visits found no water to sample (recorded as “No flow”).

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.
