EA name: CAVENHAM STR.50M U/S BARROW STW
Environment Agency sampling point AN-37M29 · 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

Latest sample: River / running surface water Monitoring (UK govt policy - not GQA or RE) · results completed 22 Sep 2026
Where: National Grid 578100, 263500As published, to the nearest 100 m (so up to about 70 m out). Open in a map
River, by its own name: Cavenham Str
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) (142 samples)

Results here were completed a median of 2 days after the sample was taken (2 to 23 days, 50 samples). 68 visits found no water to sample (recorded as “No flow”).

Everything measured here

16 determinands, each kept by its code, unit and sample material: results in different units or on different materials are never mixed. A “below” result is under the laboratory's detection limit, not zero.

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.
