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 the Skerne above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.
Named streams on the river map that flow into the Skerne and have no gauge of their own. Each has a page with what is known about it: the next gauge downstream, and any storm overflows or water-sampling points placed on it.
Woodham Burn (joins about 3.8 km above Preston-Le-Skerne)
Storm overflows upstream
34 storm overflows are traced upstream of South Park, the Skerne’s lowest gauge on the river map: on the Skerne itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of South Park: 385 spills over 1,292 hours in total, across all 34.
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 the Skerne includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

3 other overflows within 3 km of these gauges are placed below the Skerne’s lowest gauge or on another river, so not listed.
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.
54 sampling points on the River Skerne and the streams that join it above South Park, and below it. 10 have a sample from the last 12 months; 11 have any sample banked.
Sampled most recently, anywhere on the Skerne and its streams:
England's samples only. Each count opens the list of those points, nearest first, with the date of each one’s latest sample (the gauge’s “Upstream of here” list).
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.
