Clanfield is a village and civil parish about three miles (5 km) south of Carterton, Oxfordshire. The parish includes the hamlet of Little Clanfield one mile (1.6 km) west of the village, on Little Clanfield Brook which forms the parish's western boundary. The parish's eastern boundary is Black Bourton Brook and its southern boundary is Radcot Cut, an artificial watercourse on the River Thames floodplain. The 2011 Census recorded the parish's population as 879.
The nearest watercourse on the river map is Clanfield Brook, about 10 m from the middle of Clanfield's gauges. It flows into Broadwell Brook about 1.5 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 Clanfield Brook nearest the middle of Clanfield'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.
