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 Welland 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 Welland 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.
32 storm overflows are traced upstream of Deeping St James, the Welland’s lowest gauge on the river map: on the Welland itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of Deeping St James: 858 spills over 6,070 hours in total, across all 32.
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 Welland includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

1 other overflow within 3 km of these gauges is placed below the Welland’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.
107 sampling points on the River Welland and the streams that join it above Deeping St James, and below it. 47 have a sample from the last 12 months; 57 have any sample banked.
Sampled most recently, anywhere on the Welland 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.
