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 Didcot

Environment Agency gauges within 10 km of Didcot watch River Thames, Mill Brook, River Thame, Ginge Brook, River Ock, Radley Park Ditch, River Stert.

The watercourse nearest Didcot

The nearest watercourse on the river map is Ladygrove Ditch, about 570 m from the middle of Didcot's at-risk postcodes. It flows into Moor Ditch about 1.8 km downstream.

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 Ladygrove Ditch nearest the middle of Didcot'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.
