Mingyue River

　　The mother river of Da County, originating in Kaijiang County, it flows through Renshi and Jing’an, and is named after cutting through Mingyue Mountain. It then runs through Hulu, Datian, Maliu, Dafeng, Tingzi, Jiangyang, and Panshi, finally entering the Zhou River at Xiaohézuǐ in Nanwai. The entire river basin stretches over 40 kilometers in length, with the widest point exceeding 200 meters, covering an area of 133.33 hectares (over 2,000 mu). Between Datian and Dafeng at Gaogongqiao, the river is navigable for 1–3 ton wooden boats, while from Weijiadong to Jiangyang, it accommodates wooden boats under 5 tons. The entire basin is rich in hydropower resources. Hydroelectric stations such as Hulu Mingyue River, Tingzi Weijiadong, Panshi Lijiadu, Xiaohézuǐ, and Longwangtan have been developed, making significant contributions to the early industrialization of Da County, especially in ensuring power supply during the Third Front period. The riverbed cuts through the parallel mountain valleys of eastern Sichuan, providing a natural shortcut for Da County’s eastern access. Both the Dawa Highway and Dawa Railway were built along the river. The waters of the Mingyue River have irrigated and nurtured high-yield grain production areas in Wanjia, Maliu, Tanmu, Dongxing, and Tingzi. The basin lacks large cities or major industrial enterprises, so its natural vegetation remains largely intact. It produces a wide variety of high-quality, pollution-free agricultural products such as rice, rapeseed, corn, wheat, sweet potatoes, peanuts, soybeans, mung beans, fava beans, peas, pomelos, citrus, pears, plums, peaches, apricots, cherries, and walnuts, as well as many authentic Sichuan medicinal herbs. The region enjoys a highly developed agricultural economy and serves as a major granary and base for commercial grain and live pigs. The mountains feature clear waters and beautiful scenery, with uniquely majestic landscapes. This river is part of the mandatory route of the Sichuan–Kaijiang Provincial Road. The Mingyue River boasts outstanding natural beauty and convenient transportation.
