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

Ordnance Survey places 48 postcodes in Wellingborough 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 361 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 Wellingborough

Environment Agency gauges within 10 km of Wellingborough watch River Ise, River Nene.

Distances are from the middle of Wellingborough'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 Wellingborough

The nearest watercourse on the river map is Swanspool Brook, about 190 m from the middle of Wellingborough's at-risk postcodes. It flows into the River Ise about 1.2 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 Swanspool Brook nearest the middle of Wellingborough'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.
