Tributary (Left Hand) of Coledale Beck upstream of Force Cragg Mine

EA name: TRIB (LEFT HAND) COLEDALE BECK U/S FORCE (also listed as “TRIB (LEFT HAND) OF COLEDALE BECK U/S FORCE CRAGG MINE”)
Environment Agency sampling point NW-88005581 · 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.

Everything measured here

29 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.
