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.
Contains OS data © Crown copyright and database rights 2026.
Streams and rivers with a gauge whose water joins the Wye above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.
Each tributary’s water passes the gauge it joins above and every gauge below it on the Wye, and none of the gauges above where it joins. For each, the gauge nearest the Wye is shown; its own page lists the rest.

| Buxton | 0.20 mASD 1h ago | Normal |
Its water passes Buxton and every gauge below it on the Wye. It does not pass Burlington Road or the gauges above it.
Below Ashford in the Water, its water next reaches Matlock, a gauge on River Derwent, 25.5 km by river downstream.
Joins the Wye above Bourne End, its highest gauge, no more than 12.1 km by river above Bourne End.

Its water passes every gauge on the Wye, from Bourne End down.
Below Bourne End, its water next reaches Cookham Lock, a gauge on River Thames, 2.3 km by river downstream.
Tributaries and where they join are traced on the river map (OS Open Rivers, edition 2026-04) and the Environment Agency’s links between its gauges. The map holds distances between gauges, not the junctions themselves, so a junction is placed between two gauges, and no further up than the tributary’s own lowest gauge. Contains OS data © Crown copyright and database rights 2026.
102 storm overflows are traced upstream of Tintern_Abbey_Mill, the Wye’s lowest gauge on the river map: on the Wye itself, on its gauged tributaries, and on smaller streams that join above there.
Official annual figures for the overflows traced upstream of Tintern_Abbey_Mill, each return added up on its own. The Environment Agency’s return, 2025: 1,196 spills over 6,696 hours in total, across the 46 that have a figure. Welsh Water’s own return, 2025: 1,400 spills over 11,199 hours in total, across the 41 that have a figure. 15 of the 102 have no figure for 2025. 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 the Wye includes the smaller streams that join it there. Where a stretch or a tributary has more than 4, the 3 discharging now or nearest its gauge are listed, the rest are counted, and every one is in that gauge’s “Upstream of here” list.

Within 3 km of one of the Wye’s gauges in a straight line, but the river map cannot say whether their water reaches it.
6 more near these gauges whose connection is not known.
4 storm overflows are traced upstream of Ashford in the Water, the Wye’s lowest gauge on the river map: on the Wye itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Ashford in the Water: 99 spills over 710 hours in total, across all 4.
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 Wye includes the smaller streams that join it there.
Within 3 km of one of the Wye’s gauges in a straight line, but the river map cannot say whether their water reaches it.
2 other overflows within 3 km of these gauges are placed below the Wye’s lowest gauge or on another river, so not listed.
1 storm overflow is traced upstream of Bourne End, the Wye’s lowest gauge on the river map: on the Wye itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflow traced upstream of Bourne End: 5 spills over 98 hours.
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 Wye includes the smaller streams that join it there.
1 other overflow within 3 km of these gauges is placed below the Wye’s lowest gauge or on another river, so not listed.
A status is the water company’s own monitor: it says whether an overflow is discharging, never how much or why, and a spill does not by itself explain a change in a river level. A status older than two hours is shown as unknown. Annual figures are the official returns: 12/24-hour spills for England and Wales, overflow events for Scotland (Scottish Water counts differently, so the two cannot be compared). “No data” means the monitor produced no usable data that year, not zero. Overflows are placed on OS Open Rivers (edition 2026-04), which leaves out many small channels: an overflow the map cannot place may still drain here.

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.
Sampled most recently, anywhere on these rivers and their streams:
48 sampling points on the River Wye and the streams that join it above Tintern_Abbey_Mill. 25 have a sample from the last 12 months; 34 have any sample banked.

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.
