Comporté sluice gate (Niort)

Built in 1862, this navigation structure, which is still in working order, enables boats to cross the difference in level between the Comporté and La Roussille reaches. Since mid-May 2020, its renovation (restoration of the masonry structures, replacement of the metal doors and gangways, overhaul of the mechanisms) has been the responsibility of the Institution interdépartementale du bassin de la Sèvre niortaise (IIBSN), which is in charge of the public river domain. This operation is part of the project to develop tourist navigation between Niort and Marans. It follows on from the restoration work carried out on the La Tiffardière and La Roussille locks in 2018.

Many nesting birds, including herons, enjoy the tree-lined surroundings of the Comporté lock.
