República Socialista Soviética de Turkmenistán
The Main Turkmen Canal was a large-scale irrigation project in the Turkmen Soviet Socialist Republic. The canal was intended to transport water from the Amu Darya river to Krasnovodsk (now Türkmenbaşy), a city in Turkmenistan on the coast of the Caspian Sea. The canal was going to use the course of the ancient dry Uzboy River bed.
