Zhuoshui River
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 Wushe Creek and Wanda Creek (), 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 high concrete gravity dam on the Wushe Creek.
