While it is true that lock 5F in Ittre, with the inclined plane of Ronquières and the present Charleroi canal upstream, have allowed passage of 1350-tonne barges since 1968, it is interesting to note that the significant movements of water and the subsequent waves caused by the various locks have been attenuated by development of expansions upstream and downstream of the lock. And it is right in the expansion upstream that the Ittre marina has been housed, bringing with it a whole range of activities, from a number of aquatic sports to opportunities for more peaceful walks in a pastoral environment.
