The Xiluo Bridge over the Zhuoshui River

The source of the Zhuoshui River at Wuling in Hehuanshan

The river serves as an unofficial boundary between the north and south of Taiwan.[3][4][5]

It is dammed in its upper reaches by the Wushe and Wujie Dams, and further downstream by the Jiji Weir.

The Zhuoshui River environment has in recent years been seriously degraded both by the construction of a dam across the river at Jiji and by the ongoing activities of the concrete industry.
