The watercourse nearest Hillingdon

The nearest watercourse on the river map is an unnamed stream, about 10 m from the middle of Hillingdon's gauges. It flows into Yeading Brook about 2.0 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 an unnamed stream nearest the middle of Hillingdon'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.
