Aral Sea Kazakhstan.Abandoned BoatKarakalpakstan, Uzbekistan Uzbekistan was heavily irrigated during Soviet times, to provide water for growing cotton. The excessive water taken from the Amu-Darya river caused the Aral Sea to dry up. This has had devastating consequences for the region of Karakalpakstan. Here, a boat sits in what used to be the Aral Sea.

History of Aral Sea Kazakhstan.

The Aral Sea is located in southwestern Kazakhstan and northwestern Uzbekistan, near the Caspian Sea.  See map, on slide above.  

It was once twice the size of Belgium but has steadily decreased in size. 

Only a few decades ago, the Aral had:

a surface area of 64,000 square kilometers

a water volume of 1,020 cubic kilometers

an average depth of twenty to twenty-five kilometers. 

Mineralization of the sea, which was freshwater, was less than 9 grams per liter. 

Each day, 160 tons of fish were pulled from its waters.

In the 1960s, economic officials in Moscow began diverting the waters from the Syr and Amu rivers, which flow into the Aral, for use in cotton farming.  Irrigation canals were dug speedily without any type of lining, such as concrete or clay.  Due to this, the canals lose up to 40% of the water they carry before it reaches its crop or destination.  However, at the time, the large amounts of money from cotton blinded the officials to the definate future results of their actions. They pushed the cotton industry at all costs!

Currently, Kazakhstan and Uzbekistan are substituting less water intensive crops such as winter wheat, grains, soybeans, fruits, and vegetables to replace the cotton industry thus reducing some of the need for irrigation.

Its sea level is now 40 meters, its surface area 40,000 square meters, and its volume 400 cubic kilometers.

Subcontinental Divide and the Great Lakes Basin Kazakhstan.

The subcontinental divide that crosses the study area is the watershed boundary for the Great Lakes Basin. West of this divide, rivers and the waters that replenish them do not discharge to the Great Lakes but, instead, are tributary to the Mississippi River. The subcontinental divide is very close to Lake Michigan

in southeastern Wisconsin.

The map shows that more

than half the case study

area lies west of the divide

and, therefore, falls in the

Mississippi River Basin.

The Importance of Ground Water in the Great Lakes Region Kazakhstan.

Ground water helps to replenish the lake level water.
