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

Ordnance Survey places 203 postcodes in Hereford 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 2,373 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 Hereford

Environment Agency gauges within 10 km of Hereford watch River Wye, Yazor Brook, River Lugg.

Distances are from the middle of Hereford'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 Hereford

The nearest watercourse on the river map is Afon Gwy (River Wye), about 140 m from the middle of Hereford's at-risk postcodes. It flows into Afon Hafren (River Severn) about 112 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 Afon Gwy (River Wye) nearest the middle of Hereford'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.
