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.

Gauged tributaries

Streams and rivers with a gauge whose water joins the Somerset Frome 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.

2 gauged tributaries, 4 gauges

Mells River

Joins the Somerset Frome between Frome Rodden and Tellisford, no more than 12.6 km by river above Tellisford.

Stoke Bottom Farm-0.01 mASD 1h agoLow
Vallis0.09 m 1h agoNormal

Its water passes Tellisford and every gauge below it on the Somerset Frome. It does not pass Frome Rodden or the gauges above it.

Gauged streams joining the Mells River

  • Nunney Brook: joins the Mells River above Vallis (its lowest gauge is 6.4 km by river above it). Gauge, source first: Holwell Normal.

River Frome name from the river map

Joins the Somerset Frome above Tellisford, no more than 13.5 km by river above Tellisford.

FROME RODDEN BRIDGE0.26 m3/s 1h ago—

Its water passes Tellisford and every gauge below it on the Somerset Frome.

Where the Somerset Frome goes

Below Tellisford, its water next reaches Bathford, a gauge on River Avon, 16.4 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.

Storm overflows upstream

26 storm overflows are traced upstream of Tellisford, the Somerset Frome’s lowest gauge on the river map: on the Somerset Frome itself, on its gauged tributaries, and on smaller streams that join above there.

  • 0 report discharging now
  • 24 not discharging
  • 2 offline or silent: 1 monitor offline, 0 status unknown, 1 no live feed

Official figures for 2025, for the overflows traced upstream of Tellisford: 452 spills over 3,248 hours in total, across the 25 that have a figure. 1 had no usable monitor data that year.

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 Somerset Frome includes the smaller streams that join it there.

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.

Water samples

Dated samples taken by the Environment Agency, not live readings. Results are published days to months after the sample is taken, and many points are sampled only a few times a year, or have not been sampled for years.

46 sampling points on the Somerset Frome and the streams that join it above Tellisford, and below it. 9 have a sample from the last 12 months; 16 have any sample banked.

Sampled most recently, anywhere on the Somerset Frome and its streams:

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.
