Bourn is a small village and civil parish in South Cambridgeshire, England. Surrounding villages include Caxton, Eltisley and Cambourne. It is 8 miles (12 km) from the county town of Cambridge. The population of the parish was 1,015 at the time of the 2011 census.
The nearest watercourse on the river map is Bourn Brook, about 110 m from the middle of Bourn's gauges. It flows into the River Cam about 15 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 Bourn Brook nearest the middle of Bourn'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.
