Miyun reservoir

Miyun Reservoir is the largest reservoir in Asia and is known as the "Pearl of Yanshan Mountain". It is located in Miyun county, northeast of Beijing, among Yanling peaks, separated by Chaohe River and Baihe River. It was built in September of 1958-1960, with a total area of1880,000 square kilometers, a water surface of137,000 mu, and a water depth of 40 to 60 meters. It is divided into white river and tidal river.

Miyun Reservoir is located below the middle reaches of Chaohe River and Baihe River, and is formed by impounding the water of Baihe River and Chaohe River. The reservoir area spans two rivers. There are two main dams and five auxiliary dams. Among them, the main dam of Baihe River is on the Baihe River near Xiwengzhuang, with a length of 960m and a height of 66 m.. The main dam of Chaohe River is located on the Chaohe River near Nanjianchang, with a length of1.008m and a height of 56m. The five auxiliary dams are located in Beibaiyan, Zoumazhuang, Heather Camel, Xishi Camel and Jiusongshan, with a total length of 2,592 meters. Except for Zoumazhuang auxiliary dam, which is a homogeneous earth dam with a core wall, the rest are rolled earth dams with inclined clay core walls, and the dam faces are lined with stones. The total earthwork volume of the main and auxiliary dams is18.88 million cubic meters. The reservoir is designed according to the once-in-a-thousand-year flood, with a maximum water depth of 60m, a maximum water surface area of 188 square kilometers and a maximum storage capacity of 4.375 billion cubic meters. The Chaobai River basin area is controlled at 15788 square kilometers, accounting for 88% of the whole river basin area. Other supporting projects include three spillway, four spillway tunnels, a regulating pond, two hydropower stations and Jingmi diversion canal.

After the completion of Miyun Reservoir, the flood hazard of Chaobai River was fundamentally eliminated, so that more than 6 million mu of fertile land in its downstream was protected from floods, 4 million mu of dry land was turned into irrigated land, and 6,543,800 mu of newly reclaimed land was opened. The reservoir is responsible for supplying industrial, agricultural and domestic water in Beijing, Tianjin and parts of Hebei Province, and has become the most important water source in the capital. The installed capacity of the two power stations is 96,400 kilowatts, and the annual power generation is about1.1.500 million kwh. The annual output of freshwater fish in the reservoir is 3 million kilograms, so Miyun Reservoir has comprehensive benefits such as flood control, irrigation, water supply, power generation, aquaculture and tourism. Miyun Reservoir Management Office was established in 1964, with Chaohe, Baihe, Garden Management Office and Staff Hospital. * * * has 670 employees who are responsible for the maintenance, management and operation of the reservoir.
