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

Ordnance Survey places 28 postcodes in Farncombe 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 335 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 Farncombe

Environment Agency gauges within 10 km of Farncombe watch River Wey, Cranleigh Waters, River Tillingbourne, Law Brook.

Distances are from the middle of Farncombe'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 Farncombe

The nearest watercourse on the river map is Hell Ditch, about 240 m from the middle of Farncombe's at-risk postcodes. It flows into the River Wey about 500 m 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 Hell Ditch nearest the middle of Farncombe'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.
