中线工程水源取自丹江口水库。该水库建于1973年,坝高162米,正常蓄水位157米,相应库容为174.5亿立方米。初期工程的基础部分,均按后期调水要求施工,同时完成了向唐白河流域供水的清泉沟干渠、向华北调水的陶岔渠首工程。水库按后期规模续建后,使水库的正常蓄水位达到170米,相应总库容达290.5亿立方米。水库调节性能由年调节转为多年调节;综合利用任务顺序调正为防洪、供
Midline engineering water source taken from Danjiangkou Reservoir. The reservoir was built in 1973, the dam height of 162 meters, the normal water level of 157 meters, the corresponding storage capacity of 174.5 billion cubic meters. The basic part of the initial project, according to the later water diversion requirements of construction, completed the supply of water to the Tangbai Chuanquangou main canal, water diversion to North China Tao Chacui head project. After the reservoir is built according to the later scale, the normal water storage level of the reservoir will reach 170 meters and the corresponding total storage capacity will reach 29.05 billion cubic meters. The adjustment of reservoir performance will be adjusted from year to year, and the order of comprehensive utilization will be adjusted for flood control.
