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 Dart above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.

5 gauged tributaries, 6 gauges

East Dart River

Joins the Dart above Austins Bridge, its highest gauge, no more than 24.2 km by river above Austins Bridge.

Bellever0.45 m 32m agoNormal

Its water passes every gauge on the Dart, from Austins Bridge down.

River Ashburn

Joins the Dart above Austins Bridge, its highest gauge, no more than 5.1 km by river above Austins Bridge.

Ashburton Uppersensor suspect-2.57 mASD 32m ago—
Ashburton Lower0.06 mASD 32m agoLow

Its water passes every gauge on the Dart, from Austins Bridge down.

West Dart River

Joins the Dart above Austins Bridge, its highest gauge, no more than 23.7 km by river above Austins Bridge.

Dunnabridge0.26 m 1h agoNormal

Its water passes every gauge on the Dart, from Austins Bridge down.

Where the Dart goes

Below Austins Bridge, its water next reaches Totnes, 12.0 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.

Streams without a gauge

Named streams on the river map that flow into the Dart 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

9 storm overflows are traced upstream of Austins Bridge, the Dart’s lowest gauge on the river map: on the Dart itself, on its gauged tributaries, and on smaller streams that join above there.

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

Official figures for 2025, for the overflows traced upstream of Austins Bridge: 559 spills over 5,824 hours in total, across all 9.

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 Dart includes the smaller streams that join it there.

Near these gauges, connection not known

Within 3 km of one of the Dart’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.

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.

41 sampling points on the River Dart and the streams that join it above Austins Bridge, and below it. 11 have a sample from the last 12 months; 15 have any sample banked.

Sampled most recently, anywhere on the Dart 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.
