Wherwell is a village on the River Test in Hampshire, England. The name may derive from its bubbling springs resulting in the Middle Ages place name “Hwerwyl” noted in AD 955, possibly meaning “kettle springs” or “cauldron springs.” Pronunciation of the name has ranged from “Hurrell” to “Wer-rel” to present-day “Wher-well.”
The nearest watercourse on the river map is the River Test, about 10 m from the middle of Wherwell's gauges. It flows into Southampton Water about 45 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 Test nearest the middle of Wherwell'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.
