汾河水库位于太原市上游98公里的汾河干流上,地处娄烦县境内,是一座大型的综合利用水利枢纽。水库从1961年正式投入运用以来,发挥了巨大的防洪和供水效益。1967年8月10日上游入库洪峰2326米~3/秒,经水库调节后仅下泄45米~3/秒,削减洪峰98%。1985年下游兰村洪峰600米~3/秒,水库将上游1940米~3/秒的洪峰及3484万米~3的洪量全部拦蓄,保证了太原市城区段的防洪安全。水库运用29年来,年平均供水3.1亿米~3,在特大干旱的1986年全年仅来水1.43亿
Fenhe Reservoir is located 98 kilometers upstream of the Fen River in the upper reaches of Taiyuan, is located in Loufan County, is a large-scale comprehensive utilization of water conservancy hub. Since its formal application in 1961, the reservoir has exerted tremendous flood control and water supply benefits. August 10, 1967 upstream storage peak 2326 m ~ 3 / s, adjusted by the reservoir only after the release of 45 m ~ 3 / s, cut flood peak 98%. In 1985, the downstream of Lancun peak was 600m ~ 3 / s. The reservoir blocked the peak of 1940m ~ 3 / s and the flood volume of 34.84m ~ 3m in the upper reaches, ensuring the flood control safety in the urban section of Taiyuan City. In the 29 years since the reservoir was used, the annual average water supply was 310 million m 3. In the extremely arid 1986, the annual water supply was only 143 million
