The North Canal was designed and excavated by Japanese engineer Takahashi in 1934, with construction beginning that same year (Showa 9). It was completed and became operational in 1937 (Showa 12). The canal draws water from the north bank of the Beigang River in Guoxing Township and irrigates approximately 200 hectares of farmland in Butou, Sancengpu, and Buwei. The main canal stretches over 7 kilometers and includes 3 aqueducts, a siphon, 10 underdrains, and 12 culverts. The North Canal Trail connects local attractions like the Glutinous Rice Bridge, Main Canal Water Bridge, and Biyun Temple. With its gentle terrain and scenic views, the trail is perfect for family walks and leisure activities.
