Zhuoshui River
Several hydroelectric power plants have been built in the Sun Moon Lake since 1919, including Mingtan Pumped Storage Hydro Power Plant and Minhu Pumped Storage Hydro Power Station. When the first hydroelectric plant was finished in 1934, it was considered to be one of the most important infrastructure constructions of the time. Wujie Dam, also completed in 1934, diverts water from the Zhuoshui River to increase hydroelectric generation at the lake. The Jiji Line railroad was built to facilitate the construction.
