Back Brook at Stockton Moors
EA name: BACK BROOK AT STOCKTON MOORS
Environment Agency sampling point MD-28571000 · 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 Sep 2026, 10:1728 days ago · time as the Environment Agency records it (UK clock time; the source gives no time zone)
- Samples banked
- 21 since 29 Jan 2025 Imported periods: 1 Oct 2023 – 30 Sep 2026. Samples outside them are not shown here.
- Latest sample
- River / running surface water Environmental monitoring statutory (EU directives)
- Where
- National Grid 378500, 316800As published, to the nearest 100 m (so up to about 70 m out). Open in a map
- River, by its own name
- Back Brook
- River, by the map
- Not placedGrid reference only to 100 m and no line carries the name it gives, so position alone cannot choose. The river map cannot say which watercourse this is.
- Next gauge downstream
- Not known
- Why it was sampled
- Monitoring (UK govt policy - not GQA or RE) (18 samples)

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.
