history
A first lock in what was then a Mühlenstau in the town of Zehdenick was built around 1742, probably as a boiler lock . The origin of the current lock system goes back to the year 1813. The inland boatmen and raftsmen used the Havel, also known as the Schnell Havel , which flows in many bends with strongly varying widths and sometimes insufficient depths between Zehdenick and Liebenwalde . Year after year several thousand barges and rafts passed this river in spite of the poor conditions. To improve shipping conditions, a side canal was built east of the Havel . It branches off from the old part of the Voss Canal at Bischofswerder and reaches the Havel again below Zehdenick.
The Krewelin lock and the Bischofswerder lock as well as the Zehdenick building yard arche were built as further necessary structures . It serves to transfer the level peaks of the Havel into the Schnelle Havel. The free arche near Höpen serves to drain the flood of the Dölln river coming from the Schorfheide . These facilities, including the approximately 14-kilometer-long canal, were completed within two and a half years from spring 1880 to autumn 1882. The name Vosskanal, previously only used for a small canal between the Finow Canal near Liebenwalde and the Schnellen Havel near Bischofswerder, has now been transferred to the entire new canal. During the construction period of the Voss Canal between Zehdenick and Liebenwalde, the lock in Zehdenick was renewed at the same time. Since the lock was no longer able to cope with shipping traffic, it was converted from 1907 to 1909 into a so-called double-chamber lock. Both lock chambers were operated in parallel until 1911/12. The old lock chamber was finally shut down around 1930.
The lock chamber is 44.90 meters long and 9.60 meters wide. The usable length is 43.40 meters, including a safety distance of 0.75 meters from the lock gates. The water depth in the lock when underwater is 1.95 meters on average.
automation
The lock process has been fully automated since 2003 and is linked to the two-winged Hastings bridge via computer monitoring . The steel construction was built as a drawbridge in 1991/92. The lock is monitored and controlled by the Zehdenick monitoring center (ÜZZ), which went into operation in 2002. With the completion of the modernization and automation program, 27 of 39 locks, all 47 weirs as well as the 3 movable bridges in the portfolio of the Eberswalde Waterways and Shipping Office will be operated centrally, fully automatically or in automated self-service.
tourism
Since the Obere Havel waterway is no longer used by cargo ships and is only used by a few small passenger ships, it has developed into a popular area for sports boats of all sizes and classes.
