Red Strine at Dukes Drive
EA name: RED STRINE AT DUKES DRIVE
Environment Agency sampling point MD-28224200 · 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

- River / running surface water Environmental monitoring statutory (EU directives)
- Where
- National Grid 365300, 316300As published, to the nearest 100 m (so up to about 70 m out). Open in a map
- River, by its own name
- Red Strine
- 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.

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.
