Gauged tributaries
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.
River Wye — Wye
12 gauged tributaries, 30 gauges
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.

River Wye — Derbyshire Derwent
1 gauged tributary, 1 gauge
Joins the Wye between Burlington Road and Buxton, no more than 960 m by river above Buxton.
Its water passes Buxton and every gauge below it on the Wye. It does not pass Burlington Road or the gauges above it.
River Wye — Cherwell Thame and Wye
1 gauged tributary, 1 gauge
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.
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.
River Wye — Wye
Streams without a gauge
Named streams on the river map that flow into the Wye 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.
River Wye — Derbyshire Derwent
Streams without a gauge
Storm overflows upstream
River Wye — Wye
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. Every overflow traced is listed here, each stretch in full. Back to the short lists →

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.
