Huangyanghe Reservoir

Huangyanghe Reservoir is located in Liangzhou District, Wuwei City, in the eastern part of the Hexi Corridor in Gansu Province. The dam site is on the Huangyang River, 50 km southeast of Wuwei City. The reservoir controls a drainage area of 828 square kilometers. It is a medium-sized Class III annual regulation reservoir with comprehensive benefits, mainly for irrigation, but also for flood control, power generation, and tourism. The main structures are Class 3, and the secondary structures are Class 4. The current maximum dam height is 52 meters, with a total reservoir capacity of 56.44 million cubic meters and an irrigation area of 221,800 mu. The hub structures include a dam, a water conveyance tunnel, a flood discharge tunnel, and a dam-back power station. Huangyang River is a tributary of the Shiyang River system in the western inland of China. It originates from the Shuanglong Mountain, Moqi Mountain, and Heigou Mountain in Tianzhu Tibetan Autonomous County. The main tributaries are the Xiamen River and the Haxi River, which converge with the large and small gullies along the way and are intercepted by the Huangyang Reservoir at Shuixiakou in Zhonglu Township, Liangzhou District. The main road above the reservoir is 21 km long and 15–75 meters wide, with an average longitudinal slope of 1/50. The reservoir has a catchment area of 828 square kilometers, of which 637 square kilometers are outside Liangzhou District and 191 square kilometers are within Liangzhou District. The river below the reservoir flows naturally down the Shuixiakou, converges with the gullies along the way, and is then controlled by the head of the Huangyang River Canal to be introduced into the canal for irrigation. The river course from the reservoir to the head of the canal is 7.2 km long. During the flood season, some of the floodwater flows down the river and into the Zamu River, with National Highway 312 and the Lanzhou-Xinjiang Railway passing through its lower reaches.
