This machine, designed and built in 1868, following the decree of Napoleon III of 11 April 1866, contrasts by its technique with that of Trilbardou. It remained operational until the end of navigation on the canal, around 1962. It was classified as a historic monument in 1987. Its vertical turbines and pumps are currently maintained in working order and run most of the time during scheduled opening days. Thanks to its design, it could be automated and reused if necessary. It is the work of Louis-Dominique Girard.
