The Norder Tief was initially a direct connection from the Leybucht to the port of the city of Norden. The increasing siltation of the estuary was countered in 1929 with the construction of the Leybuchtsiel . Since the surface water could only flow away when the water was low , an additional pumping station was built in 1962 .
The progressive silting up of the Leybucht made shipping on the Watts fairway more and more difficult. Until 1991, the upstream artificial peninsula Leyhörn with the Leysiel and a storage basin and the Leyhörner Sieltief, which also served as an access to Greetsiel , was built west of the Leybucht . To the east of it, the Störtebeker dike was built as a new flood protection structure, while the Störtebeker Canal was built in the 1990s as a connection between the Leyhörner Sieltief and the old Leybuchtsiel at the mouth of the riverNordertiefs . Since then, the Norder Tief has drained through this canal, the Leyhörner Sieltief and the Leysiel into the North Sea .
