The Liujiaxia Dam (simplified Chinese: 刘家峡大坝; traditional Chinese: 劉家峽大壩; pinyin: Liújiāxiá Dàbà) is a major hydroelectric dam on the upper Yellow River, in Linxia Hui Autonomous Prefecture of China's Gansu Province. The dam and its hydroelectric facility (Liujiaxia Hydroelectric Station, simplified Chinese: 刘家峡水电站; traditional Chinese: 劉家峽水電站; pinyin: Liújiāxiá Shuǐdiàn Zhàn) are located in Liujia Gorge, or Liujiaxia (literally, "Liu Family's Gorge"), just downstream from where the Tao River flows into the Yellow River. The site is on the eastern outskirts of Liujiaxia Town. Since Liujiaxia Town is the county seat of Yongjing County, it is often marked on less detailed maps simply as "Yongjing".
The Liujiaxia Reservoir (simplified Chinese: 刘家峡水库; traditional Chinese: 劉家峽水庫; pinyin: Liújiāxiá Shuǐkù) formed by the dam is the largest body of water within Gansu. The primary purpose of the dam is generating electricity; in addition, it is used for flood control, irrigation, and "ice flood prevention". The dam's location is about 70 km (43 mi) west-south-west (or 100 km (62 mi) upstream) from the provincial capital Lanzhou.
