River Poulter
 The River Poulter which rises near Scarcliffe in Derbyshire England is a tributary river of the River Idle in Nottinghamshire. It supplied power to mills along its route most of which are now gone although their mill ponds remain. Cuckney mill building is used as a primary school. The river has been dammed to create several lakes in the Dukeries estates of Welbeck Abbey and Clumber House now the National Trust property of Clumber Park.
