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 Taw above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.
Named streams on the river map that flow into the Taw 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.
Bullow Brook (joins about 21 km above Newnham Bridge)
Ford Brook (joins about 2.5 km above Newnham Bridge)
Mully Brook (joins about 2.1 km above Newnham Bridge)
Storm overflows upstream
32 storm overflows are traced upstream of Barnstaple, the Taw’s lowest gauge on the river map: on the Taw itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of Barnstaple: 1,969 spills over 20,427 hours in total, across all 32.
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 Taw includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

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.
91 sampling points on the River Taw and the streams that join it above Barnstaple. 38 have a sample from the last 12 months; 49 have any sample banked.
Sampled most recently, anywhere on the Taw 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.
