Etwall
EA name: ETWALL (also listed as “RSN0230 ETWALL”)
Environment Agency sampling point MD-RSN0230 · 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
- 5 Dec 2024, 12:1022 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
- 15 since 17 Oct 2023 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 428624, 334189As 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), 2 m from the line.
- Next gauge downstream
- Egginton On the Egginton Brook · 8.4 km along the river
- 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.
