Astley Brook above confluence with Eagley Brook
EA name: ASTLEY BROOK ABOVE CONF WITH EAGLEY BK (also listed as “ASTLEY BROOK ABOVE CONFLUENCE WITH EAGLEY BROOK”)
Environment Agency sampling point NW-88002267 · 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
15 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.
