Marham is a village and civil parish in the English county of Norfolk, approximate 12 miles (19 km) away from King's Lynn. An RAF station, RAF Marham, is situated nearby at Upper Marham.

The nearest watercourse on the river map is the River Nar, about 10 m from the middle of Marham's gauges. It flows into the River Great Ouse about 18 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 Nar nearest the middle of Marham'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.
