Deerness at A690

EA name: DEERNESS AT A690
Environment Agency sampling point NE-44400011 · 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: 6 Mar 2025, 11:4219 months 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: 18 since 30 Oct 2023 Imported periods: 1 Oct 2023 – 30 Sep 2026. Samples outside them are not shown here.
Latest sample: River / running surface water Monitoring (national agency policy)
Where: National Grid 425490, 540945As published, to the nearest 1 m. Open in a map
River, by its own name: Deerness
River, by the map: River DeernessPlaced on the river its name gives, 2 m from the line.
Next gauge downstream: Burn Hall On the River Browney · 3.7 km along the river

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.
