In the 1960s it was the 4th largest lake in the world and ever since it has been reducing in size. By the end of the 20th century, the lake had reduced to 1/10 of its original size.

The Aral Sea also split into the North and South Aral Sea and the eastern and western basins of the lake. By 2009 the South Aral Sea dried into a thin strip of water. The eastern basin of the Aral Sea had completely dried up by the year 2014. This region is now called the Aralkum Desert.
