The Yamdrok Hydropower Station (), also known as the Yamdrok Yumtso or Yamzhog Yumcog hydropower station, is a hydroelectric power station just north of Yamdrok Lake, about southwest of Qüxü. The power station is in the Lhoka (Shannan) Prefecture of the Tibet Autonomous Region, China. Opposition to using the lake, considered holy, delayed construction at first. The project ran into difficulties and was two years late, completed in 1998. Water is taken from the natural lake through long tunnels, without the need for a dam, and the power station discharges it into the Yarlung Tsangpo River. The design is a pumped-storage system, where off-peak power from other generators on the grid is used to pump water back into the lake when power is not needed. However, the river water has high levels of sediment and nitrates compared to the lake, and lower levels of minerals. Pumping may upset the lake's ecosystem, while not pumping may drain it. ==Plans== Yamdrok Tso is the largest freshwater lake in southern Tibet, with a surface area of at an elevation of . It drains an area of . Some Tibetans consider that the Yamdrok Yumtso or Scorpion Lake, is holy and contains the spirit of Tibet. The Panchen Lama criticized the project. It was started in 1985, but due to vocal opposition from Tibetans and the intervention of the Panchen Lama the project was halted in 1986. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yamdrok Hydropower Station」の詳細全文を読む スポンサード リンク
