Gurgy flood gates - River Yonne - Gurgy - France - Waterway Locks, Planes and Lifts on Waymarking.com

These are flood gates on the River Yonne at Gurgy. They are at the southern entrance to the 4km cut called Derivation de Gurgy.

The gates are only closed when the River Yonne goes into flood and the navigation is closed to boats

Over the first 22km, down to the junction with the Canal de Bourgogne, it forms part of the Nivernais route, a cross link between the Bourgogne and Bourbonnais routes from Paris to Lyon. The rest of the waterway forms part of the Bourgogne route, the shortest but most heavily locked of the three main routes across central France. The Yonne is an attractive cruising river, with huge locks but little commercial traffic (except in the lower reaches). The river is avoided by lock-cuts at three places: Gurgy, Joigny and Courlon.

History – The river was a free-flow navigation through the ages, until Poirée successfully tested in 1834 (near Clamecy) his design for a needle weir. The design was improved by Thenard five years later, and the Government then approved works to canalise many rivers on this basis. One weir and lock were built on the Yonne after 1840, but most of the works were conducted from 1861. The locks were enlarged to Freycinet standards in the late 19th century, then again to their current dimensions after World War II.
