Gunthorpe Stream Thornage Bridge (River Glaven)
EA name: GUNTHORPE STR.THORNAGE BRIDGE (R.GLAVEN)
Environment Agency sampling point AN-GLV026 · 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 Planned investigation (local monitoring)
- Where
- National Grid 604900, 336000As published, to the nearest 100 m (so up to about 70 m out). Open in a map
- River, by its own name
- Its name does not give one
- 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

Everything measured here
13 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.
