Ollerton is a village and former civil parish, now in the parish of Ollerton and Boughton, in the Newark and Sherwood district, in the county of Nottinghamshire, England, on the edge of Sherwood Forest in the area known as the Dukeries. The population of Ollerton and Boughton at the 2011 census was 9,840.
The nearest watercourse on the river map is Whitewater (River Maun), about 10 m from the middle of Ollerton's gauges. It flows into the River Maun about 2.7 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 Whitewater (River Maun) nearest the middle of Ollerton'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.
