Shiyazi Dam
The Shiyazi Dam is a concrete gravity dam on the Hongjiadu River, a tributary of the Wu River, in Wuchuan County, Guizhou Province, China. The primary purpose of the dam is hydroelectric power generation. Construction on the dam began in 2007 and concrete pouring in April 2008. The reservoir began to impound in September 2010. The dam was "capped off" with concrete on 24 December 2011 and the generators were commissioned a week later on 31 December. The dam, being located in a steep portion of Meilin Canyon, was difficult to construct. The 134.5 m (441 ft) tall dam withholds a reservoir with a capacity of 321,500,000 m (260,644 acre⋅ft) and was constructed with both normal concrete and roller-compacted concrete. The dams power station is located 320 m (1,050 ft) downstream and contains two 70 MW Francis turbine-generators for an installed capacity of 140 MW.
