Banan Weir

The Banan Weir is a concrete structure that holds back the Luye River to store and manage water for the surrounding region. It distributes water in a controlled way to support irrigation across the farmland in Taitung.

The structure was built during the 1970s and 1980s, building on water management plans from the earlier Japanese colonial period. It has operated for decades before undergoing major renovation following a severe typhoon.

The weir supports the farming communities that depend on it for irrigation across the Taitung region. Locals view the structure as essential infrastructure that shapes how water reaches their fields and sustains agricultural work.

The best time to visit is during the dry season when water levels are stable and the paths around the structure stay clear. Access is straightforward, but note that the area is rural with limited facilities nearby.

Following a typhoon in the 2010s, the weir was rebuilt using advanced concrete technology to make it more resistant to future storms. This reinforcement shows how engineers adapt to local hazards through modern techniques.
