陕西省旬阳县平定河属汉江二级支流,坝河水系。水库建设在平定河中游,1958年动工,1960年主体工程完工,坝高24.7米,总库容为124.6万立方米,其中滞洪库容19.4万立方米,有效库容91.3万立方米,死库容13.9万立米。由于泥沙淤积严重,1977年测定淤积库容92.8万立方米,占总库容的74.5%,不能满足灌溉需要。1977年坝体加高3.7米,坝高达
Pingding River, Xunyang County, Shaanxi Province is a secondary tributary of the Han River and dam river system. The reservoir was built in the middle reach of Pingding River and started construction in 1958. The main project was completed in 1960 with a dam height of 24.7 meters and a total storage capacity of 1.246 million cubic meters, of which 194,000 cubic meters of stagnant flood storage capacity, 913,000 cubic meters of effective storage capacity and 139,000 cubic meters of dead storage capacity . Due to the serious sedimentation, in 1977 the measured siltation capacity of 928,000 cubic meters, accounting for 74.5% of the total capacity, can not meet the needs of irrigation. In 1977 the dam body height 3.7 meters, dam up
