Geesthacht Weir on the Elbe

The bike path on the bridge is narrow but smooth. You can drive well and enjoy the fantastic views of the Elbe. Stop quietly or at least drive a little slower ....

The Geesthacht barrage, which was put into operation in 1960, is located southwest of the Schleswig-Holstein town of Geesthacht and dams the water of the Elbe at 4 m above sea level. NN. It thereby limits the tidal influence of the North Sea upstream; the weir defines the end of the Inner Elbe. In addition to the Cracauer waterfall, a permanent low-water weir on the Old Elbe near Magdeburg, it is the only barrage in the course of the river in Germany. [1] The barrage consists of a weir with a fish pass and a lock channel with a double lock. Another fish pass was completed in September 2010.
