Düpe ( Low German for depth , in this case water depth) or Düpekommission is the name of a 1555 in Hamburg , is the maintenance of sufficient introduced Office, which had the task of water depth in the port of Hamburg and the inner city canals and channels to care. The two youngest councilors in each case were the heads of this authority as dupher . The execution was incumbent on the Fleetenkiekern . The cleaning of the canals was ordered in Burspraken and could be instructed directly by the Düpeherren .

Maintaining the water depth necessary for port operations was already a problem with the first systems in the Alster loop , caused by constant sediment deposits in the meandering rivers, the dependence of the Elbe inland delta on tides and the frequent storm surges . From the 13th century onwards, the people of Hamburg tried to counteract this with hydraulic engineering measures and regulations for the fairway . A sufficient draft in the port area for shipping has been instructed since the Middle Ages by the allocation of places for ballast dumping and waste disposal using ballasters . As early as 1359, a fine of three silver marks was threatened for violations.

With the French occupation , the Düpe Commission was repealed in 1806. In 1814, the tasks were transferred to the newly created shipping and port deputation, which later became the office for electricity and port construction .
