3 gauges. None is above its typical high. 4 storm overflows upstream are discharging now. Gauges in Carmarthenshire; levels are checked every 15 minutes.

| Station | Level now | Status |
|---|---|---|
| Login River Station | 1.40 m 32m ago | Within its typical range |
| Clog Y Fran River Station 19.3 km by river | 2.00 m 17m ago | Within its typical range |
These gauges are filed under the Taf, but the river map places them on another watercourse, so they are not in the Taf’s order above.
| Llanddowror River Stationon Allt Cwmbrwyn | 0.37 m 17m ago | Within its typical range | ||
| Its water and the Taf’s meet further down, below Clog Y Fran River Station: neither is upstream of the other. | ||||
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 Taf above one of its gauges, from the source down. The river map knows where gauges are, not every stream, so a tributary without a gauge is not listed here.
Joins the Taf between Login River Station and Clog Y Fran River Station, no more than 5.5 km by river above Clog Y Fran River Station.
| Whitland River Station | 0.63 m 32m ago | Within its typical range |
Its water passes Clog Y Fran River Station and every gauge below it on the Taf. It does not pass Login River Station or the gauges above it.
No gauge below Clog Y Fran 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.

9 storm overflows are traced upstream of Clog Y Fran River Station, the Taf’s lowest gauge on the river map: on the Taf itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Clog Y Fran River Station: 845 spills over 11,326 hours in total, across all 9.
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 Taf includes the smaller streams that join it there.
Within 3 km of one of the Taf’s gauges in a straight line, but the river map cannot say whether their water reaches it.
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.
