South Aral Sea : ウィキペディア英語版 | South Aral Sea
The South Aral Sea was a lake in the basin of the former Aral Sea which formed in 1986 when that body divided in two, due to diversion of river inflow for agriculture. In 2003 the South Aral Sea itself split into eastern and western basins, the ''Eastern Sea'' and the ''West Aral Sea'', connected by a narrow channel (channel bed at an elevation of ) that balanced surface levels but did not allow mixing, and in 2005 the North Aral Sea was dammed to prevent the collapse of its fisheries, cutting off the only remaining inflow to the southern lakes. In 2008 the Eastern Sea split again, and in May 2009 had almost completely dried out, leaving only the small permanent Barsakelmes Lake between the Northern and Western Seas and increasing the expanse of the Aralkum desert. In 2010, it was partially filled again by meltwater, and by 2014 was once again dry. The West Aral Sea has some replenishment from groundwater in the northwest, and so is likely to avoid desiccation. ==Background== The Aral Sea began shrinking in the 1960s, when the Soviet Union decided that the two rivers feeding it, the Amu Darya and the Syr Darya, would be diverted to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1986, due to an accelerated loss of water, the Aral Sea was split into northern and southern parts; the northern part is the current North Aral Sea.
