2 gauges from Cwm Rheidol River Station to Llanbadarn River Station. None is above its typical high. Gauges in Ceredigion; levels are checked every 15 minutes.
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 Rheidol 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.
None of the storm overflows FloodRadar holds is traced upstream of Llanbadarn River Station 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.
Near these gauges, connection not known
Within 3 km of one of the Rheidol’s gauges in a straight line, but the river map cannot say whether their water reaches it.
