Flood lines for this path: parts can start to flood at 0.40 mASD · usually properly flooded above 0.65 mASD
This flood line starts from this gauge’s measured history — the level the river only tops a few days a year. Reports of a flooded or passable day will tune it to the path itself.
Through the year
Over the past year the river reached the level where parts of this path can start to flood on about 6 days, mostly in November and February to March, but didn’t reach the level where it’s usually properly flooded.
At its highest the river stayed 17 cm below the level where the path usually floods properly.
From this gauge’s own record over the year to July 2026, measured against the level we estimate this path floods at. It’s a guide to the season, not a forecast.
About this path
A flat mile and a quarter of the Thames Path across the National Trust's Magna Carta meadows between Old Windsor and Egham. This is undefended floodplain: the Trust itself warns that the riverside paths flood in the winter months, and the January 2024 floods inundated the meadows and closed the road alongside.
