Aldbourne is a village and civil parish about 6 miles (10 km) north-east of Marlborough, Wiltshire, England. It is in a valley on the south slope of the Lambourn Downs – part of the North Wessex Downs Area of Outstanding Natural Beauty. From here an unnamed winterbourne flows south to join the River Kennet 4 miles (6 km) away near Ramsbury. The 2011 Census recorded the parish population as 1,833. The parish includes the hamlets of Upper Upham and Woodsend and part of the hamlet of Preston, which straddles the boundary with Ramsbury. The village of Snap became deserted in the early 20th century.
The river map has no watercourse within 1 km of the middle of Aldbourne's gauges.
That means this spot is not on the river map, not that there is no water here: Ordnance Survey’s river map (OS Open Rivers) leaves out small streams, ditches and culverts. Contains OS data © Crown copyright and database rights 2026.
