The two major rivers that feed into the Aral Sea are the Syr Darya and the Amu Darya. I will give you a little information on each that way you can pick which river you'd like. The Syr Darya originates in the Tian Shan Mountains in Kyrgyzstan and eastern Uzbekistan and is the northern and the eastern part of the river that flows into the Aral Sea. The Amu Darya is formed by the junction of the Vakhsh and Panj Rivers and flows directly into the Aral Sea.
