It is also referred to as Coral Lake ({{zh|c=珊瑚潭|p=Shānhútán|labels=no}}) 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.[1] OverviewConstruction 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.[2] 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.[3] EngineeringThe reservoir was built in conjunction with the Chianan Canal, also designed by Hatta.[2] At the time of its completion, Wusanto Reservoir was the largest reservoir in Asia and the third largest in the world.[1] Construction of the reservoir and of the Wusanto Dam used an uncommon semi-hydraulic fill technique, where fine-grained material is placed at the end of an embankment and then washed into its desired position using jets of water; this is a variant of the hydraulic fill technique.[4] Wusanto Reservoir is the only project constructed with the semi-hydraulic fill technique that is still in use anywhere in the world. This process was expensive and time-consuming, but produced a dam which has proven resistant to Taiwan's severe seismic activity.[3] Scenic areaToday, the Wusanto Reservoir Scenic Area is a popular tourist destination in Tainan. The area includes a memorial and museum for Yoichi Hatta. Cherry blossom viewing is a popular event in spring. The area is also known for its abundant native flora and fauna.[5] See also
