Constructed during the Japanese colonial period in 1932, the Baileng Canal was designed and supervised by Japanese engineer Keno Isoda and named by the Director of the Bureau of Productive Industries, Government-General of Taiwan. In 1954, tailwater from the Tianlun Power Plant was diverted across the Dajia River into the Baileng Canal. As a result, the canal utilizes two water sources: river intake and power plant tailwater. This system irrigates 760 hectares of farmland. The 16.6 km long canal is characterized by its precarious route along mountainsides, featuring open and closed channels, tunnels, flumes, and inverted siphons. The construction was extremely challenging, emphasizing the importance of cherishing our water resources.
