Wujie Dam (Chinese: 武界壩; pinyin: Wǔjiè Bà) is a concrete gravity dam on the Zhuoshui River in Ren'ai Township, Nantou County, Taiwan. The dam was built in two stages, from 1919–1922 and 1927–1934, and serves primarily to divert water from the Zhuoshui River to a storage reservoir at Sun Moon Lake and its associated hydroelectric projects (Mingtan Pumped Storage Hydro Power Plant and Minhu Pumped Storage Hydro Power Station). During the Japanese occupation of Taiwan it was known as Bukai Dam.
The dam is located in a narrow gorge about 15 kilometres (9.3 mi) northeast of Sun Moon Lake. It is 57.6 metres (189 ft) high and 86.5 m (284 ft) long, forming a reservoir with a design capacity of 14,000,000 m3 (11,000 acre·ft), now mostly silted up. The diversion tunnel to Sun Moon Lake has a diameter of 3 m (9.8 ft), with a diversion capacity of 40.35 m3/s (1,425 cu ft/s). The spillway of the dam consists of six gates with a capacity of 3,150 m3/s (111,000 cu ft/s).
