Crondall is a village and large civil parish in the Hart district, in the north east of Hampshire in England, in the Crondall Hundred surveyed in the Domesday Book of 1086. The village is on the gentle slopes of the low western end of the North Downs range, and has the remains of a Roman villa. Despite the English Reformation, Winchester Cathedral held the chief manors representing much of its land from 975 until 1861. A large collection of Anglo-Saxon and Merovingian coins found in the parish has become known as the Crondall Hoard. In 2021 the parish had a population of 1724.

The nearest watercourse on the river map is an unnamed stream, about 80 m from the middle of Crondall's gauges. It flows into the River Hart about 80 m 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 Crondall'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.
