Tuyamuyun Hydro Complex


The Tuyamuyun Hydro Complex is a system of four interconnected reservoirs and a series of canals on the lower Amu Darya River, bordering Uzbekistan and Turkmenistan. Its primary purpose is to provide water for irrigation in Xorazm, Karakalpakstan and Daşoguz regions of Uzbekistan, Turkmenistan and as far north as Kazakhstan. The complex is located about southeast of Urgench in Xorazm Region, Uzbekistan and about north of Gazojak in Lebap Region, Turkmenistan. It was constructed between 1969 and 1983. Aside from irrigation, the complex also provides water for industrial and municipal uses. A 150 MW power station on the main dam contains six 25 MW hydroelectric turbine-generators.
The main dam is located on the Amu Darya, straddling the border of Uzbekistan and Turkmenistan. It is the center-piece of the complex. The main dam is a long and long gravity dam. It creates the Channel Reservoir which has a storage capacity of about and length of. Water from the Channel Reservoir can be fed into the adjacent Kaparas and Sultansanjar Reservoirs for later use. The Sultansanjar Reservoir is connected via a canal to the Koshbulak Reservoir which lies just east. When first completed, all four reservoirs had a capacity of about but due to silt build-up, this had been reduced to about by 2001. A system of canals off the main dam supply a network of irrigation canals to the various regions for irrigation.
