| Station | Level now | Status |
|---|---|---|
| Forge Bridge River Station | 0.38 m 33m ago | Within its typical range |
| Tir Y Dail River Station 6.3 km by river | 0.98 m 18m ago | Within its typical range |
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 Loughor (Llwchwr) above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.
Joins the Loughor (Llwchwr) between Forge Bridge River Station and Tir Y Dail River Station, no more than 3.3 km by river above Tir Y Dail River Station.
| Llandybie River Station | 0.46 m 18m ago | Within its typical range |
Its water passes Tir Y Dail River Station and every gauge below it on the Loughor (Llwchwr). It does not pass Forge Bridge River Station or the gauges above it.
No gauge below Tir Y Dail River Station is known on the river map.
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.

4 storm overflows are traced upstream of Tir Y Dail River Station, the Loughor (Llwchwr)’s lowest gauge on the river map: on the Loughor (Llwchwr) itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Tir Y Dail River Station: 414 spills over 6,421 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 Loughor (Llwchwr) includes the smaller streams that join it there.
Within 3 km of one of the Loughor (Llwchwr)’s gauges in a straight line, but the river map cannot say whether their water reaches it.
11 other overflows within 3 km of these gauges are placed below the Loughor (Llwchwr)’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.
