What the Environment Agency's rivers-and-sea flood-risk data says about Ashford

Ordnance Survey places 147 postcodes in Ashford in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 2,518 properties in the EA dataset's likelihood bands.

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 Ashford

Environment Agency gauges within 10 km of Ashford watch River Ash, River Thames, River Colne, Wraysbury River, Colne Brook.

Distances are from the middle of Ashford's at-risk postcodes. Tidal and structure gauges are shown as readings only — the tide and sluice gates move them, not floods. A gauge with no recent reading shows no level.

The watercourse nearest Ashford

The nearest watercourse on the river map is the River Ash, about 770 m from the middle of Ashford's at-risk postcodes. It flows into the River Thames about 7.3 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 the River Ash nearest the middle of Ashford'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.
