Wushoh Dam (Chinese: 霧社水庫; pinyin: Wùshè Shuǐkù, also spelled Wushe Dam) is a gravity dam on the Wushoh Creek (霧社溪), a tributary of the Zhuoshui River, located near Ren-ai Township in Nantou County, Taiwan. The dam was completed in 1960 after seven years of construction, and serves mainly to generate hydroelectric power.
When Taiwan was under Japanese rule in 1934, hydroelectric plants were constructed at Sun Moon Lake to generate power from the fall of the Zhuoshui River. The Japanese also sought to build power stations upstream on Wushoh Creek and Wanda Creek (萬大溪), the two main tributaries that combine to form the Zhuoshui. A reservoir would be required to control the flow of water to the power stations and serve the dual purposes of flood control and trapping sediment. In 1939, construction began on a 97-metre (318 ft) high concrete gravity dam on the Wushoh Creek.
When World War II broke out in 1941, industrial resources were increasingly diverted to the war effort and construction was halted in 1944 with only the power plants and 6 percent of the dam complete. After the war, Taiwan Power Company (Taipower) took over the project with aid from the United States Agency for International Development. The U.S. Bureau of Reclamation consulted on a re-design which increased the dam height to 114.6 metres (376 ft). Construction resumed in May 1953. The reservoir first filled in 1957, and the project was officially completed in August 1960, at a cost of NT$376,077,000.
