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

Ordnance Survey places 464 postcodes in Thornton 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 9,124 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 Thornton

Environment Agency gauges within 10 km of Thornton watch Horsebridge Dyke, Lune And Wyre, Cockers Dyke, Broad Fleet.

Distances are from the middle of Thornton'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.

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 Royles Brook nearest the middle of Thornton'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.
