The Aral Sea started showing shrinkage in the 1960’s and it lasted until about 2009
-
The northern aral sea (small aral sea) had separated from the southern aral sea (large aral sea)
-
The southern aral sea had split into eastern and western lobes that remained connected at both ends
-
By 1990 the volume of the sea had shrunk by 75%
-
Canals and shores were abandoned and boats were left to rot on the dry sea bed
-
By 2001 the connection was shallow. and the shallower eastern part retreated over the next several years
-
With the loss of so much water the climate around the lake became more extreme
-
A seven-mile dam is being built across a small northern section of the shrunken Aral Sea in Central Asia
-
Large boundaries in the eastern lobe of the southern sea occurred sometime between 2005 and 2009
-
To save some of the lake kazakhstan built a dam between the northern and southern parts of the sea in 2005
-
The salty dirt blew off of the lake beds and then settled onto fields
-
The water became increasingly salty and it became polluted with fertilizers and pesticides.
-
Water levels rise and fall irregularly annually between 2009 and 2012 in the Kazakh dam
