黄土溪水库位于湖南省麻阳县境内,坝址控制流域面积461平方公里,大坝为宽缝重力坝,坝高35.5米,正常高水位185.0米,相应库容4,660万立方米。枢纽工程于1965年冬开工,1971年基本建成,因大坝不满足抗滑稳定要求于1975年进行加固,即在溢流坝鼻坎末端修一混凝土拱坝, The loess reservoir is located in Mayang County, Hunan Province. The dam site controls a drainage area of ​​461 square kilometers. The dam is a wide-gap gravity dam with a dam height of 35.5 meters and a normal high water level of 185.0 meters with a corresponding storage capacity of 46.6 million cubic meters. The pivot project started in the winter of 1965 and basically completed in 1971. Since the dam did not meet the requirements of anti-skid stability, it was reinforced in 1975, that is, a concrete arch dam was repaired at the end of the nose of the overflow dam,
