Rivers and flooding history near TD9

The rivers that matter here, each monitored live on FloodRadar:

Newcastleton on the Liddel Water — 6.2 km away
Rowanburnfoot on the Liddel Water — 10.2 km away
Canonbie on the River Esk — 12.2 km away, highest on record 4.36m
Canonbie on the Esk (Solway) — 12.2 km away

The Environment Agency's warning record covers England only, so it holds nothing for this location — that is the reach of the record, not a quiet place. This location sits where the banked postcodes span two nations, so FloodRadar cannot say which record ought to cover it. Natural Resources Wales's and SEPA's records were searched as well and neither can place a warning within 10 km — but NRW cannot place roughly one warning in nine in its own record at all, and the Scottish record only begins on 15 September 2026, so this is not a confirmed none.

The Environment Agency's Recorded Flood Outlines cover England only, so there is no mapped flood record here to be empty — this is an absence of coverage, not an absence of floods.
