Brislington Brook at the Rock

EA name: BRISLINGTON BROOK AT THE ROCK
Environment Agency sampling point SW-Z1010538 · 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

No results were published for this point in the imported periods. That says nothing about the water: it was not sampled then, or its results are not public yet. Its newest sample in the archive, from 21 Nov 2017, is older than that and is not imported 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.
