North Jane Deep Adit

EA name: NORTH JANE DEEP ADIT (also listed as “NORTH JANE DEEP ADIT DISCHARGE TO CALENICK STREAM”)
Environment Agency sampling point SW-81940425 · 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
29 May 2024, 10:552.3 years 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 30 Sep 2026 and had nothing newer.
Samples banked
1 since 29 May 2024 Imported periods: 1 Oct 2023 – 30 Sep 2026. Samples outside them are not shown here.

Everything measured here

51 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.
