The reservoir was formally completed on September 1, 1960.[3]
The Miyun Reservoir is the largest comprehensive water conservancy project in North China.[4] The reservoir covers an area of 180 square kilometers,[5] with a reservoir capacity of 4 billion cubic meters and an average depth of 30 meters, making it the largest[6] and only source of drinking-water supply for Beijing,[7] serving over 11 million people.[8]
The Miyun Reservoir is the largest artificial lake in Asia[9] and is billed as the "Pearl in North China" (华北明珠).[10]
Construction of the Miyun Reservoir started on 1 September 1958[11] and was completed in September 1960.[12] The chief designer of the project was Zhang Guangdou.[13]
The Miyun Reservoir was designed by the Department of Water Resources of Tsinghua University,[14] with the participation of a large number of migrant workers from Beijing, Tianjin and Hebei, and the Engineering Bureau of the Ministry of Water Resources and Electric Power.[15]
Along the Miyun Reservoir, there is a 110-kilometer-long Huanku Road (环库公路).[16]
