The River Drone is a river which flows south from its source on the Sheffield, South Yorkshire, border. It flows through Dronfield, Unstone and Unstone Green in Derbyshire before merging at Sheepbridge to the north of Chesterfield with the Barlow Brook. Below the junction, it is often referred to as the River Whitting. It then flows south-east till it merges with the River Rother at Brimington Road North (B6050) at Chesterfield. It is one of the three main tributaries of the Rother.[1][2]
