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

Ordnance Survey places 168 postcodes in Leigh 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 2,574 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 Leigh

Environment Agency gauges within 10 km of Leigh watch Westleigh Brook, Atherton Lake Brook, Shakerley Brook, Ellenor Brook, Carr Brook, Hey Brook, Borsdane Brook, Glaze Brook, Millingford Brook.

Distances are from the middle of Leigh'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 Leigh

The nearest watercourse on the river map is Westleigh Brook, about 670 m from the middle of Leigh's at-risk postcodes. It flows into Pennington Brook about 2.1 km downstream. (Leeds and Liverpool Canal is nearer, about 530 m, but a canal is not followed.)

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 Westleigh Brook nearest the middle of Leigh'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.
