The Zengwen River is a significant waterway located in southern Taiwan. It flows through the Chiayi and Tainan regions, eventually emptying into the Taiwan Strait. The river is approximately 100 kilometers long and plays a crucial role in local agriculture and irrigation. The river is also known for the Zengwen Dam, which is one of the largest dams in Taiwan. This dam helps manage water resources, control flooding, and generate hydroelectric power. The surrounding area is rich in biodiversity, making it an important habitat for various plant and animal species.
