Ma'an Dam

Ma'an Dam is a gravity dam stretching 240 meters across the Dajia River with nine spillway gates that regulate water flow throughout the year. The concrete structure stands 16.3 meters high and holds a reservoir containing nearly 1 million cubic meters of water.

Construction of this hydroelectric facility began in 1992 and finished in 1998, completing the final stage of power development along the Dajia River. This project expanded the region's energy infrastructure during Taiwan's period of industrial growth.

The dam infrastructure represents Taiwan's commitment to renewable energy development, contributing to the modernization of the country's power generation capabilities.

The dam can be viewed from several vantage points along the Dajia River, with accessible paths on both banks allowing visitors to see the structure and spillways. Weather conditions can change quickly in this area, so come prepared with appropriate clothing for varying temperatures.

Two turbines at the connected power station in nearby Xinshe generate around 410 million kilowatt-hours of electricity annually from this dam's water flow. Many visitors overlook how efficiently the nine spillway gates work together to maintain precise water control for both power generation and irrigation needs.
