The Liujiaxia Dam ( Chinese  劉家峽 水壩  /  刘家峡 水坝 , Pinyin Liújiāxiá Shuǐba ) is a larger dam in China on the middle upper reaches of the Yellow River , which dams it to the Liujiaxia Reservoir. The reservoir is also called Bingling (= ten thousand Buddhas) lake because of the Bingling temple on the north bank. The dam and hydropower plant are in the Chinese province of Gansu in the Linxia Autonomous District near the city of Yongjing . 1.5 km upstream, the Tao River flows into the Yellow River.

The barrier structure is a 147 m high and 204 m long gravity dam . The total crown length of 840 m consists of several individual structures, including auxiliary walls and dams on both sides.

The hydropower plant , which produces 1225 MW, was the first large Chinese hydropower plant with more than 1000 MW. It was planned with Soviet help. It has five Francis turbines with generators that deliver three 225 MW, one 250 MW and one 300 MW, a total of 1225 MW. According to other information, it is 1160 MW. The construction work began on September 27, 1958 and the impoundment in October 1968. Commissioning was on April 1, 1969. The fifth and last turbine was not put into operation until December 5, 1974.

The reservoir serves the following purposes: flood protection, irrigation, ice control, performance increase by 50% of the hydropower plants located below

• Yanguoxia ( 36 ° 3 '33 "  N , 103 ° 16' 22"  O ),
• Bapanxia ( 36 ° 8 '16 "  N , 103 ° 24' 31"  O ), and
• Qingtongxia ( 37 ° 53 ′ 4 ″  N , 105 ° 59 ′ 27 ″  E ),

Water supply, fishing, navigability, recreational recreation.
