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 Bran 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.
No gauged tributary joins the Bran above Llandovery River Station on the river map. Streams without a gauge are not counted here.
Below Llandovery River Station, its water next reaches Manorafon River Station, a gauge on Tywi, 20.7 km by river downstream.
No gauged tributary joins the Bran above Dosmucheran on the river map. Streams without a gauge are not counted here.
Below Dosmucheran, its water next reaches Arcan Spillway, a gauge on Conon, 35.7 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.

1 storm overflow is traced upstream of Llandovery River Station, the Bran’s lowest gauge on the river map: on the Bran itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflow traced upstream of Llandovery River Station: 48 spills over 182 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 Bran includes the smaller streams that join it there.
Within 3 km of one of the Bran’s gauges in a straight line, but the river map cannot say whether their water reaches it.
1 other overflow within 3 km of these gauges is placed below the Bran’s lowest gauge or on another river, so not listed.
None of the storm overflows FloodRadar holds is traced upstream of Dosmucheran on the river map. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.
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.
