The Shihmen Management Office of the Irrigation Agency, Ministry of Agriculture, formerly known as the Taiwan Shihmen Irrigation Association, was established on January 1, 1964, and continues to operate today. The Yangmei Workstation manages the Huanding Lateral Channel, which sources water from the Shihmen Main Canal. The canal crosses Provincial Highway 1, National Highway No. 1, and railway lines, supplying water to six lateral canals: Guangxing, Shuanglianpo, the tea factory, Liugu, Xipengji, and Laofandian. In 2022, a greening project was implemented to enhance patrol safety and functionality, extending from Youshi Road to Qingnian Road, thereby supporting local development and providing public recreational space.
