Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. * p9 s! z9 A0 vtvb now,tvbnow,bttvb & C* J! b, i: h1 e7 b3 Y9 \, E( `5.39.217.76Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997.
