The 'Garabogazköl', alternatively the 'Kara-Bogaz-Gol' (literally "mighty strait lake") is a shallow inundated depression in the northwestern corner of
Turkmenistan. It forms a bay of the
Caspian Sea with a surface area of about 7,000 mi² (18,000 km²). The translation "black strait lake" is a misunderstanding of the old Turkic name. It is separated from the Caspian, which lies immediately to the west, by a thin
sandbar having a narrow opening through which the Caspian waters flow, cascading down into Garabogazköl. The water volume of the bay fluctuates seasonally with the Caspian Sea; at times it becomes a large bay of the Caspian Sea, while at other times its water level drops drastically.
Salt
The
salinity of the bay is about 35%, compared to the Caspian Sea's 1.2% and 3.5% for the world's
oceans. Because of the exceptionally high salinity it has practically no marine vegetation. Large salt deposits accumulated at the south shore were harvested by the local population since the
1920s, but in the 1930s manual collection stopped and the industry shifted northwest to its present center near
Bekdash, a town of about 10,000 on the shore of the Caspian Sea. From the
1950s on, ground water was pumped from levels lower than the bay itself, yielding more valuable types of salts. In
1963 construction began at Bekdash on a modern plant for increased production of salines, all the year round and independently of natural evaporation. This plant was completed in
1973.
In the 1980s, the resulting "salt bowl" caused widespread problems of blowing salt, reportedly poisoning the soil and causing health problems for hundreds of kilometers downwind to the east.
Miscellaneous
The bay is also the subject of
Konstantin Georgiyevich Paustovsky's
1932 book ''Kara-Bogaz''.
