Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 8 D/ f!

The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. 7 s* V) t0 ^, t( l" v* i公仔箱論壇 5 n1 G$ u& [, j( V+ ~* A$ F5.39.217.77:8898Construction 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.
