| Dike Kokaral ： ウィキペディア英語版 |
Dike Kokaral is a levee across a narrow stretch of the Aral Sea, splitting off the North Aral Sea (also called "The Small Sea") from the much larger South Aral Sea ("The Large Sea"). The dike is conserving the dwindling waters of the Syr Darya river and maintaining (and attempting to revive) the damaged ecology of the North Aral Sea, at the expense of sealing the fate of the larger South Aral. Work was completed in August 2005. Dike Kokaral is named after the Kokaral peninsula (an island until the 1960s), which would connect it to the other shore of the Aral Sea and separate the northern from the southern seas.==History==As the waters of the contributory rivers to the Aral have been progressively redirected for irrigation, the water levels in the Aral have fallen, the shore receded, and the water quality has dropped precipitously.The dike was built twice in the past from local sand, but due to a lack of funding necessary to strengthen it once the water level in the North Aral Sea (and therefore pressure to the dike) began to rise, the dike was washed away. This happened in 1992 and 1998. However, for the short time that the dike stood, positive changes were already noticed - the climate became milder, and fauna was partly restored. When the dike was washed away, the water-level fell again, as much of the water poured into the South Aral Sea. In some places the coastline of North Aral retreated by as much as a few hundred meters.

==History==
As the waters of the contributory rivers to the Aral have been progressively redirected for irrigation, the water levels in the Aral have fallen, the shore receded, and the water quality has dropped precipitously.
The dike was built twice in the past from local sand, but due to a lack of funding necessary to strengthen it once the water level in the North Aral Sea (and therefore pressure to the dike) began to rise, the dike was washed away. This happened in 1992 and 1998. However, for the short time that the dike stood, positive changes were already noticed - the climate became milder, and fauna was partly restored.
