Which rivers were the main sources of water for the Aral Sea?

The two main rivers that served as the primary sources of water for the Aral Sea are the Syr Darya in the north and the Amu Darya in the south.1

Historically, these rivers discharged into the Aral Sea and maintained its water levels. However, beginning in the mid-20th century, the Soviet government diverted massive amounts of water from both rivers for agricultural irrigation, particularly for cotton cultivation. This diversion caused the rivers to dry up before reaching the lake, leading to the sea's dramatic shrinkage and severe environmental degradation in the region.1234
