Reservoir dam introduction: Jinta Yuanyangchi Reservoir spillway has 11 holes on the weir gate, with a total width of 100 meters, a net width of 76 meters, and a weir top elevation of 1318.00 meters. During the flood season, the waves are turbulent, the water roars, and the waves spray. The splashing, flying waterfalls and flowing colors are just like the Milky Way falling in the sky, and the scenery is spectacular. On both sides of the spillway is the Jinta Yuanyanghu Reservoir Dam. It is the first earth-rock dam reservoir built in my country using modern science and technology, and is a milestone in China's dam engineering construction.
