The '''Tuyamuyun Hydro Complex''' (THC) is a system of four interconnected [[reservoir]]s 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 Region|Daşoguz]] regions of [[Uzbekistan]], [[Turkmenistan]] and as far north as [[Kazakhstan]].<ref name=regions>{{cite book|last1=Qi|first1=edited by Jiaguo|last2=Evered|first2=Kyle T.|title=Environmental problems of Central Asia and their economic, social and security impacts|date=2008|publisher=Springer|location=Dordrecht, the Netherlands|isbn=1402089600|pages=284-287|url=https://books.google.com/books?id=AOLwNLF_RkUC&pg=PA284&lpg=PA284&dq=tuyamuyun+reservoir&source=bl&ots=xlYYzVUD1V&sig=-8qhnkf5cCQwDiXfypR19hd_hdU&hl=en&sa=X&ei=9862VK77EsKnggSW_YCYCQ&ved=0CEgQ6AEwBw#v=onepage&q=tuyamuyun%20reservoir&f=false|accessdate=14 January 2015}}</ref> The complex is located about {{Convert|74|km|mi|abbr=on}} southeast of [[Urgench]] in [[Xorazm Region]], Uzbekistan and about {{Convert|2|km|mi|abbr=on}} north of [[Gazojak]] in [[Lebap Region]], Turkmenistan.<ref>{{cite book|last1=Olsson|first1=edited by Oliver|last2=Bauer|first2=Melanie|title=Interstate water resource risk management : towards a sustainable future for the Aral Basin (JAYHUN)|date=2010|publisher=IWA Publishing|location=London|isbn=1843393085|pages=87-90|url=https://books.google.com/books?id=_AkmmEztL2kC&pg=PA88&lpg=PA88&dq=tuyamuyun+reservoir&source=bl&ots=_lCb9ObDit&sig=33G15--Dy_T18fPcOdxiQKMYjx4&hl=en&sa=X&ei=9862VK77EsKnggSW_YCYCQ&ved=0CDAQ6AEwAw#v=onepage&q=tuyamuyun%20reservoir&f=false|accessdate=14 January 2015}}</ref> It was constructed between 1969 and 1983. Aside from irrigation, the complex also provides water for industrial and [[municipal water|municipal]] uses. A 150 MW power station on the main dam contains six 25 MW [[hydroelectric]] turbine-generators.<ref>{{cite web|title=Irrigation and Drainage Systems in Khorezm, Uzbekistan|url=http://www.zef.de/fileadmin/webfiles/downloads/projects/khorezm/downloads/Publications/wps/WP12_Awan.pdf|publisher=Zentrum für Entwicklungsforschung Center for Development Research|accessdate=15 January 2015|page=9|date=December 2011}}</ref>

The main dam (THC 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 {{Convert|141|m|ft|abbr=on}} long and {{Convert|25|m|ft|abbr=on}} long [[gravity dam]]. It creates the '''Channel Reservoir''' which has a storage capacity of about {{Convert|2300000000|m3|acre.ft|abbr=on}} and length of {{Convert|102|km|mi|abbr=on}}. 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 {{Convert|7800000000|m3|acre.ft|abbr=on}} but due to silt build-up, this had been reduced to about {{Convert|6700000000|m3|acre.ft|abbr=on}} by 2001. A system of canals off the main dam supply a network of irrigation canals to the various regions for irrigation.<ref name=regions/>
