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 Exe Estuary 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, 29 gauges
Each tributary’s water passes the gauge it joins above and every gauge below it on the Exe Estuary, and none of the gauges above where it joins. For each, the gauge nearest the Exe Estuary is shown; its own page lists the rest.
Joins the Exe Estuary above Lympstone, its highest gauge, no more than 990 m by river above Lympstone. Nearest the Exe Estuary: Lympstone Longbrook LaneNormal.
Where the Exe Estuary goes
No gauge below Lympstone is known on the river map.
90 storm overflows are traced upstream of Lympstone, the Exe Estuary’s lowest gauge on the river map: on the Exe Estuary itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of Lympstone: 2,621 spills over 25,947 hours in total, across all 90.
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 Exe Estuary includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

2 other overflows within 3 km of these gauges are placed below the Exe Estuary’s lowest gauge or on another river, so not listed.
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.
184 sampling points on the Exe Estuary and the streams that join it above Lympstone. 57 have a sample from the last 12 months; 75 have any sample banked.
Sampled most recently, anywhere on the Exe Estuary 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.
