松林攔河堰, Water control structure in Nantou County, Taiwan.
The Songlin Weir is a concrete water control structure with adjustable gates located in Nantou County that distributes water to surrounding farmland. The installation features multiple spillways and channels designed to move water efficiently toward irrigation areas downstream.
The weir was built during Taiwan's effort to modernize its irrigation infrastructure for agricultural expansion. It represents a shift toward centralized water management that supported farming development across the island.
The weir functions as an educational site where students learn about water resource management and agricultural sustainability in Taiwan.
You can view the weir from designated observation areas, though working sections are off-limits to the public. It helps to check ahead whether specific viewing areas are open when you plan to visit.
The structure maintains precise water levels through an integrated system of spillways that respond to seasonal precipitation patterns.
