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 Frome 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 Frome — Frome, Piddle, Poole Harbour and Purbeck
Streams without a gauge
Named streams on the river map that flow into the Frome 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.

Storm overflows upstream
River Frome — Frome, Piddle, Poole Harbour and Purbeck
13 storm overflows are traced upstream of East Stoke, the Frome’s lowest gauge on the river map: on the Frome itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of East Stoke: 374 spills over 5,488 hours in total, across all 13.
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 Frome includes the smaller streams that join it there.

England's samples only. Each count opens the list of those points, nearest first, with the date of each one’s latest sample (the gauge’s “Upstream of here” list).
FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
