刘家峡离兰州一百公里。刘家峡水电站工程,要在峡内筑成一百四十八公尺高的拦河坝,坝的上游将形成一个大水库;正常水位时,水库面积为一百三十平方公里,水库容量为五十七亿公方。电站安装的水轮发电机,容量为一百零五万瓩,每年平均可发电五十亿度,供兰州使用。水库的水还可以灌溉兰州到包头间共一千五百八十万亩的农田,可以维持银川到清水河段长八百三十公里的航运。水库又能调节洪水,减轻洪水对兰州市的威胁。
Liujiaxia hundred kilometers away from Lanzhou. In the project of Liujiaxia Hydropower Station, a dam with a height of 148 meters should be constructed in the gorge. A large reservoir will be formed in the upstream of the dam. When the water level is normal, the reservoir area will be 130 square kilometers and the reservoir capacity will be 57 Billion public square. Hydropower generators installed in the power station have a capacity of 1.05 million tons and generate an average of 5 billion kilowatt-hours annually for Lanzhou use. Water in the reservoir can also irrigate a total of 15.8 million mu of farmland between Lanzhou and Baotou to maintain a navigation of 830 kilometers long from Yinchuan to Qingshuihe. The reservoir can regulate the flood and reduce the threat of flood to Lanzhou City.
