位于黄河中游北干流上的第一个梯级开发枢纽工程——万家寨水利枢纽,是以供水为主,兼发电、防洪、防凌,具有综合效益的大型水利工程。黄河在万家寨年水量为249亿m~3,每立方米含沙量仅6.9kg(到三门峡时含沙量达39kg)是黄河北干流含沙量最小的河段。枢纽大坝长438m,库容为8.96m~3,最高水位980m。向山西供水工程从水库948m高程处引水,到偏关下土寨为总干渠,全长43.5km,引水流量为48m~3/s,年引水
Located in the middle reaches of the Yellow River north of the first cascade development cascade project - Wanjiazhai Water Control Project, is based on water supply, and power generation, flood control, anti-Ling, with comprehensive benefits of large-scale water conservancy project. The Yellow River in Wanjiazhai annual volume of 24.9 billion m ~ 3, only 6.9 kg per cubic meter of sediment (to Sanmenxia sediment content of 39kg) is the Yellow River north of the stream sediment minimum. Hub length of 438m, storage capacity of 8.96m ~ 3, the highest water level of 980m. To Shanxi water supply project from the reservoir height of 948m Department of water diversion, to the partial off under the village as the main canal, a total length of 43.5km, water diversion flow of 48m ~ 3 / s, the annual diversion
