Wehr Märkt
  Märkt dam
upstream divide of the Rhine river and the Grand Canal
  Originally planned by the German administration as a separate lateral canal to make navigation independent fromthe unrealiable water level of the Rhine between Basle and Strasbourg the construction of the canal was taken on by France as part of the peace settlement. Interrupted by WW II, works continued in 1948. The Vogelgrun lock, put into operation in 1956, with a dam at the lower end of the river's course marked the end of this project, the further regulation of the Rhine following another concept with locks and dams being built in the river.
