Ordnance Survey places 125 postcodes in Caversham in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea).

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.

Rivers and live river levels near Caversham

Environment Agency gauges within 10 km of Caversham watch River Thames, River Kennet, River Loddon, Sulham Brook, River Pang.

The watercourse nearest Caversham

The nearest watercourse on the river map is the River Thames, about 430 m from the middle of Caversham's at-risk postcodes. It flows on to the sea.

A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Thames nearest the middle of Caversham'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.
