Live levels from 3 monitoring stations across Somerset, updated every 15 minutes.
| Station | Level now | Status | ||
|---|---|---|---|---|
| Stogumber Escott Lane | 0.10 m 58m ago | Normal | ||
| 3.5 km by river | ||||
| Sampford Brett | -0.02 mASD 1h ago | Low | ||
| 3.8 km by river | ||||

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 Doniford Stream 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 Doniford Stream between Sampford Brett and Swill Bridge, no more than 3.6 km by river above Swill Bridge.
| Williton | 0.00 mASD 1h ago | Low |
Its water passes Swill Bridge and every gauge below it on Doniford Stream. It does not pass Sampford Brett or the gauges above it.
No gauge below Swill Bridge 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.

4 storm overflows are traced upstream of Swill Bridge, Doniford Stream’s lowest gauge on the river map: on Doniford Stream itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Swill Bridge: 59 spills over 337 hours in total, across all 4.
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 Doniford Stream includes the smaller streams that join it there.
Within 3 km of one of Doniford Stream’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.

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.
6 sampling points on the Doniford Stream and the streams that join it above Swill Bridge. 1 has a sample from the last 12 months; 2 have any sample banked. Listed from the source down, grouped by the next gauge each one's water reaches.

Distances are along the river to the gauge named. England's samples only.
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.
