Project Overview Sanmen County under the reservoir in early November 1958 started in April 1960 to complete the Department of clay core earth dam. Normal storage 400000 m ~ 3, the corresponding reservoir water level 20.3m (Yellow Sea elevation, the same below). It was expanded in 1979 and completed in 1979. The height of the dam is 16m, the height of the crest is 280m, the total storage capacity is 1,673,000m 3, the corresponding reservoir water level is 26.05m, the normal storage capacity is 1,246,000m 3, and the corresponding reservoir water level is 24.5m. An area of 3872 acres. After the completion of the project, when the reservoir water level exceeds 20.3m, the whole dam will see water leakage and downstream
