Stations are listed from source to mouth as the water flows, traced on the river map (OS Open Rivers) and the Environment Agency’s own links between its gauges. A distance “by river” is along the river, and is shown only where the map traces the path.
Streams and rivers with a gauge whose water joins Pentre Brook above one of its gauges, from the source down. The river map knows where gauges are, not every stream, so a tributary without a gauge is not listed here.
33 storm overflows are traced upstream of Buckley Farm, Pentre Brook’s lowest gauge on the river map: on Pentre Brook itself, on its gauged tributaries, and on smaller streams that join above there.

Official annual figures for the overflows traced upstream of Buckley Farm, each return added up on its own. The Environment Agency’s return, 2025: 144 spills over 687 hours in total, across the 5 that have a figure. Welsh Water’s own return, 2025: 634 spills over 4,535 hours (2 of them gave no duration) in total, across the 28 that have a figure. These are two separate returns, so the figures are given side by side, not added together.
Each overflow is listed in the stretch above the first gauge its water reaches, from the source down, as on the Gauges tab. A stretch of Pentre Brook includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

Dated samples taken by the Environment Agency, not live readings. Results are published days to months after the sample is taken, and many points are sampled only a few times a year, or have not been sampled for years.
30 sampling points on the Pentre Brook and the streams that join it above Buckley Farm. 8 have a sample from the last 12 months; 12 have any sample banked. Listed from the source down, grouped by the next gauge each one's water reaches.

Distances are along the river to the gauge named. England's samples only.
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.
