鹹海
The North Aral Sea (, ) is the portion of the former Aral Sea that is fed by the Syr Darya River. It split from the South Aral Sea in 1987–1988 as water levels dropped due to river diversion for agriculture. The poorly built Dike Kokaral intended to contain the North Aral Sea and save its fisheries failed twice, but in 2005, the government of Kazakhstan was able to fund a more robust design. Since then, water levels have risen faster than expected and fish stocks have increased. Plans to build a second dike to increase water levels further were due to begin in 2010, but have so far not materialized.
