Ochre Dike at Hagg Wood
EA name: OCHRE DIKE AT HAGG WOOD
Environment Agency sampling point NE-49305372 · 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
- 9 Mar 2026, 12:368 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 28 Oct 2026 and had nothing newer.
- Samples banked
- 12 since 23 Apr 2025 Imported periods: 1 Oct 2023 – 28 Oct 2026. Samples outside them are not shown here.

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.
