The Lijiaxia Dam (Chinese: 李家峡水库) is a concrete arch-gravity dam on the Yellow River in Jainca County, Qinghai Province, China. The dam houses a hydroelectric power station with 5 x 400 MW generators for a total installed capacity of 2,000 MW. Construction began in April 1988 and the reservoir began to fill on December 26, 1996. On January 26, 1997, the initial reservoir operating level was reached and the first generator was commissioned in February.[1]
