鳶山堰
Yuanshan Weir is a river weir on the Dahan River in Sanxia District, Taiwan, built to divert water toward local supply systems and manage river flow. It has eighteen fixed sluice gates along its body, with overflow channels that activate when water levels rise beyond a set point.
Construction of the weir took place between 1978 and 1983, replacing older and less reliable water control structures along the Dahan River. After completion, the Taiwan Water Resources Agency took over its management and has operated it ever since.
The weir draws locals who walk the paths along the water on weekends and holidays. When water spills over the overflow channels after heavy rain, people gather nearby to watch the flow, which is a familiar sight for residents of the district.
A walkway runs along the structure, giving visitors a close view of the sluice gates and the river below. After periods of heavy rain, the overflow channels are active and the water flow is more visible, making the visit more rewarding.
The name 鳶山 refers to a nearby hill whose outline is said to resemble a black kite, a bird of prey common in the area, hovering over the water. This connection between the local landscape and the name of the weir is something most visitors passing by would not know.
