Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. 8 y1 G4 B E7 l, Q$ V9 X& X5.39.217.77:8898 * K2 B, r- j7 P: x5.39.217.77:8898Construction 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.
