The watercourse nearest Woolston

The nearest watercourse on the river map is the River Itchen (tidal here), about 10 m from the middle of Woolston's gauges. It flows into Southampton Water about 2.4 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 Itchen nearest the middle of Woolston'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.
