This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.

Environment Agency gauges within 10 km of Penton Hook watch River Thames, Chertsey Bourne, River Ash, Wraysbury River, River Colne, Addlestone Bourne.

The watercourse nearest Penton Hook

Two mapped watercourses are about the same distance from the middle of Penton Hook's at-risk postcodes: the River Thames (about 310 m) and Abbey River (about 400 m), so this page cannot say which one is nearer to you.

Distances along the river are from the point on each watercourse nearest the middle of Penton Hook's at-risk postcodes. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
