The Dead Sea is situated where the river Jordan ends, just 24 kilo-
meters east of Jerusalem. It is really a lake. It extends for about 74 kilo-
meters and is 16 kilometers wide so it is quite small but it is extremely
deep – about 300 meters. The surface of the Dead Sea, 408 m. below sea
level as of 1996, is the lowest water surface on earth.
The Dead Sea is fed mainly by the Jordan River, which enters the
lake from the north. The lake has no outlet, and the heavy inflow of fresh
water is carried off solely by evaporation, which is rapid in the hot desert
climate. The resulting salt deposits form an enormous salt reserve. Due to
large-scale projects by Israel and Jordan to divert water from the Jordan
River for irrigation and other water needs, the surface of the Dead Sea
has been dropping for at least the past 50 years.
Originally, the Dead Sea was about the same size as today. Then
the climate of the area changed and became wetter. This change caused
the Dead Sea to grow longer. However, after some time, the climate
changed again and the lake returned to its original size and shape.
Nearly seven times as salty as the ocean, The Dead Sea contains
some 27 percent solid substances. Because of the density of solids in the
water, the human body easily floats on the surface. The lake contains no
life of any sort except for a few kinds of microbes; sea fish put into its
waters soon die.
The Dead Sea is economically important as a source of potash, bro-
mine, gypsum, salt, and other chemical products which are extracted inex-
pensively. The shores of the Dead Sea are of growing importance as a winter
health resort. The lake is closely associated with biblical history; the sites of
the cities of Sodom and Gomorrah are believed to lie beneath the lake.
Nearly 20 years ago there was a plan to build a canal between the
Dead Sea and the Mediterranean. This would make the level of the water in
the Dead Sea go up. However, the cost of doing this is so enormous that the
project cannot go ahead yet. So, at the moment nothing is being done.
