The nearest watercourse on the river map is the River Cray, about 30 m from the middle of Crayford's gauges. It flows into the River Darent (Dartford Creek) about 3.3 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 the River Cray nearest the middle of Crayford's gauges. 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.
