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 Hambleton

Environment Agency gauges within 10 km of Hambleton watch River Aire, Roall Dyke, Aire Washlands, Selby Dam, River Ouse, Wheelan Dyke, River Wharfe, The Fleet.

Distances are from the middle of Hambleton'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 Hambleton

The nearest watercourse on the river map is Town Dike, about 110 m from the middle of Hambleton's at-risk postcodes. It flows into Selby Dam about 2.7 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 Town Dike nearest the middle of Hambleton'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.
