Wushantou Reservoir (Chinese: 烏山頭水庫; pinyin: Wūshāntóu Shuǐkù), sometimes spelled Wushanto or Wusanto, is a reservoir and scenic area located in Lioujia District and Guantian District of Tainan, Taiwan. It is also referred to as Coral Lake (珊瑚潭; Shānhútán) due to its zigzagging shoreline. The reservoir was designed by engineer Yoichi Hatta and was the largest in Asia at the time of its completion in 1930. In 2009 it was listed as a potential World Heritage Site.
Construction of the Wusanto Reservoir began in 1920 and was completed in 1930. The goal of the project was to provide irrigation for over 100-thousand hectares of farmland in the Chianan area. After construction of the reservoir, the irrigation plain became an important producer of rice for consumption in Taiwan and Japan, with three rice harvests possible each year.
