1 Project Overview The Bazijiai Reservoir is located in the middle reaches of Puhe, a tributary of the Jinghe River in Qingyang, Gansu Province, with a control basin area of 352,200 hm ~ 2. The reservoir was built in 1958 and built in 1962 as a homogeneous loess with a height of 58m. The height of the dam was 58m. After 1964 and 1973, the reservoir was raised twice and the existing dam height was 74m. The crest elevation is 1124.7m, with a total storage capacity of 511 million m ~ 3. The design flood standard of reservoirs is designed according to the flooding once in 100 years and the flooding in 2000. The left bank of the reservoir originally had a diameter of 4m spillway tunnel, the maximum discharge of 102m ~ 3 / s, a diameter of 2m diversion tunnel, the maximum flow of 35m ~ 3 / s. The first and second level power plants have been built up at the exit. The installed capacity of the power station is 2084KW. In 1981, there were 9 electric power irrigation projects with a total installed capacity of 26,500KW and lifting capacity of 4.86m ~ 3 / s, which can supply water and irrigate cultivated land to Xifeng City
