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

Ordnance Survey places 20 postcodes in South Cave 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 110 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 South Cave

Environment Agency gauges within 10 km of South Cave watch South Cave Beck, Mires Beck, Brough Clough, Ings Beck, Market Weighton Canal, Weighton Lock, West Clough, Back Delfin.

The watercourse nearest South Cave

The nearest watercourse on the river map is an unnamed stream, about 760 m from the middle of South Cave's at-risk postcodes. It flows into Ferry Beck about 440 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 an unnamed stream nearest the middle of South Cave'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.
