Niederfinow lock staircase

The four-step lock staircase Niederfinow in the north of the district of Barnim in Brandenburg was the oldest lock structure at the eastern end of the crest in the Oder-Havel Canal. The western end is the Lehnitz lock near Oranienburg. The staircase was in operation from 1912 to 1972. In 1934, the Niederfinow ship lift was put into operation at the same time. The latter will be decommissioned by 2025 at the latest and replaced by the larger Niederfinow Nord ship lift under construction next to it.
The head of a total of 36 m was overcome by four chamber locks with exactly the same construction method except for the foundation. Each lock had a usable chamber length of 67 m and a clear width of 10 m, which allowed it to be used by ships up to 600 t. All locks were built as economy locks, i.e. three savings basins were connected on each side of each lock basin, which reduced the water loss during the lock to 40%. Upper and lower gates were miter gates.
