River Idle

The River Idle is a river in Nottinghamshire, England, formed by the confluence of the River Maun and the River Meden near Markham Moor. It flows north from its source through Retford and Bawtry before joining the River Trent at West Stockwith. Its main tributaries are the River Poulter and the River Ryton. The river is navigable as far as Bawtry, with a statutory right of navigation extending to Retford. Much of the land surrounding the Idle consists of broad flood plain, and the river is significant for conservation, with several Sites of Special Scientific Interest being designated along its course.
