The source of the brook is on the edge of the Nottinghamshire Wolds, near Old Dalby, Leicestershire. It initially flows in a northerly direction, and then turns west passing through the villages of Widmerpool, and Bunny. It crosses Bunny and Ruddington moor, and then flows north between Clifton and the village of Ruddington. The brook joins the River Trent near Silverdale, on the outskirts of Nottingham near Clifton Bridge.
