Drain at Canonteign Barton above the confluence with River Teign
EA name: DRAIN @ CANONTEIGN BARTON PTCW R.TEIGN (also listed as “DRAIN FROM CANONTEIGN BARTON PTCW RIVER TEIGN”)
Environment Agency sampling point SW-70630018 · Freshwater - rivers · listed as open (“open” does not mean it is sampled now)
These are samples taken on a date, not live readings of the river. Results reach the Environment Agency's archive days to months after the sample is taken, so the newest here may be weeks or months old. FloodRadar does not grade them.

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.
