Mingtan Reservoir Introduction
Mingtan Reservoir is located at the confluence of the Shui-li Township and the Yu-chih Township, in the Shui-li Creek valley, adjacent to the 131 Line highway. It was constructed by utilizing the terrain of the Shui-li Creek valley to build a dam for storing the tailwater from Sun Moon Lake's power generation, creating an artificial lake. Mingtan and Minghu Reservoirs, located in Checheng Village, are environmentally friendly "pumped-storage power plants" built for hydropower generation. The power plant uses elevation differences for pumped-storage hydroelectricity, which not only adjusts the power supply during peak and off-peak times but is also pollution-free. The lower dam of Mingtan Reservoir is a concrete gravity dam, and the reservoir forms a crescent-shaped water area with a water storage capacity of 12 million cubic meters. The water level fluctuates by 28 meters daily, creating a unique tidal phenomenon in the lake. In the early morning, the swirling clouds and mist present a transcendent scene. The lake surface is situated below the highway, so whether viewing the lake from the highway above or enjoying the lakeside, one can deeply appreciate the tranquil and idyllic atmosphere of clear mountains and waters.
