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.
Contains OS data © Crown copyright and database rights 2026.
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.
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. Nearest the Exe Estuary: Topsham; 27 more gauges further up. Gauged streams joining it: River Haddeo, River Barle, River Batherm, River Lowman, River Culm and River Creedy.
Joins the Exe Estuary above Lympstone, its highest gauge, no more than 990 m by river above Lympstone. Nearest the Exe Estuary: Lympstone Longbrook Lane Normal.
No gauge below Lympstone 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.

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. Where a stretch or a tributary has more than 4, the 3 discharging now or nearest its gauge are listed, the rest are counted, and every one is in that gauge’s “Upstream of here” list.

Within 3 km of one of the Exe Estuary’s gauges in a straight line, but the river map cannot say whether their water reaches it.
6 more near these gauges whose connection is not known.
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.
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.
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:
| Where, from the source down | Sampling points | Newest sample |

| Above Lympstone Longbrook LaneWotton Brook · joins the Exe Estuary above Lympstone | 1 point | 5 Aug 2026 |
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.
