Aral Sea Surface Water Depletion

In normal conditions, the Aral Sea gets approximately one fifth of its water supply through rainfall, while the rest is delivered to it by the Amu Darya and Syr Darya rivers.

Not only was all this water being diverted into canals at the expense of the Aral Sea supply, but the majority of it was being soaked up by the desert and blatantly wasted (between 25% and 75% of it, depending on the time period).

The Soviet government decided in the 1960s to divert those rivers so that they could irrigate the desert region surrounding the Sea rather than supply the Aral Sea basin

Water Levels

The primary effect of the Aral Sea has been the significant loss of water in the sea. The water level has dropped approximately 23 meters since its primary sources of water being diverted

Population Change

Population

Between 1950 and 1988, the population of the Aral Sea basin grew dramatically.

  • Increases from 8.1 to 19.9 million in Uzbekistan,
  • 1.0 to 2.2 million in Kirghizstan,
  • 2.0 to 5.1 million in Tadzhikistan,
  • 1.5 to 3.5 million in Turkmenistan, and 1.2 to 2.4 million in Kazakhstan
  • (all within the sea-basin limits)

Location

The Aral Sea is situated in Central Asia, between the Southern part of Kazakhstan and Northern Uzbekistan. Up until the third quarter of the 20th century it was the worlds fourth largest saline lake, and contained 10grams of salt per liter.
