Cetian reservoir water source
The water source of Cetian Reservoir mainly came from the middle and upper section of Sanggan River basin. Sanggan River originates from Miaoergou of Guancen Mountain in Ningwu, passes through Ningwu and Yangfangkou, and receives Qili River at Taipingyao Reservoir in Shuocheng District. Then it is called Sanggan River after Nayuanzi River near Qinghe Temple, 1 km downstream of Mayi in Shuocheng District. The Sanggan River avoided the northeast from the southwest and flowed through the entire Datong Basin before finally entering the area of the Cetian Reservoir. Therefore, the water source of Cetian Reservoir came from the Sanggan River basin.
Water Diversion Project of Cetian Reservoir

Cetian reservoir opens the gate to discharge water
In the spring of 2022, the Cetian Reservoir opened its gates and released water to the lower reaches of the Yongding River, marking the full start of the ecological replenishment of the Yongding River in the spring of 2022. The purpose of opening the floodgates was to revive the ecological environment of the Yongding River and ensure the water supply. Through years of multi-water source allocation and unified dispatch of ecological water volume, up to now, the ecological replenishment of the Yongding River was nearly 960 million cubic meters, and the 865-kilometer river channel was fully connected to the water. The water quality had improved significantly. This move also had a significant impact on the improvement of the water ecological environment in Mentougou District Beijing City. The ecological replenishment work of the Yongding River would continue to be carried out to ensure that there was water throughout the entire Yongding River.
Is Cetian reservoir opening its gate to release water?
Yes, Datong's Cetian Reservoir opened its gates to release water for the Yongding River's spring ecological replenishment. The water replenishment plan was to ensure that the Yongding River had water all year round and to supply the lower reaches of the river. Datong's Cetian Reservoir was one of the important water resources nodes in the upper reaches of the Yongding River. According to the plan of the Ministry of Water Resources, this year's water replenishment work was expected to last until June 25. It was planned to complete the local water delivery of 15 million cubic meters and discharge 84 to 96 million cubic meters of water from the Yellow River. It was estimated that 64 to 78 million cubic meters of water would enter the Guanting Reservoir.
Where does the water of Cetian reservoir come from?
The water of Cetian Reservoir came from the Yellow River and Hebei Friendship Reservoir. The Yellow River was diverted from the Wanzhai Reservoir at the junction of Shanxi and Inner Mongolia. The Yellow River water flowed into the Sanggan River through the Qili River and then flowed to the Guanting Reservoir. In addition, Hebei Friendship Reservoir also released water to Cetian Reservoir.

Cetian Reservoir Administrative Bureau
The Cetian Reservoir Administration Bureau was an organization located in the north of the West Cetian Village in Yunzhou District, Datong City, Shanxi Province. It was mainly responsible for the management and monitoring of the Cetian Reservoir. The reservoir was located in the middle and upper reaches of the Sanggan River in the Yongding River system of the Haihe River Basin. It was a large reservoir. Its original design mission was irrigation, sand interception, and flood control. Later, it was changed to industrial water supply, irrigation, and flood control. It also took on the task of irrigation and water supply to Beijing City. Up to now, the reservoir has accumulated 218 million cubic meters of siltation, which has played a significant role in irrigation agriculture, reducing siltation in Guanting Reservoir and flood control safety in the downstream areas. In addition, Cetian Reservoir also participated in the spring ecological replenishment work of Yongding River, delivering about 80 million cubic meters of water to the lower reaches of Yongding River. Datong City's Cetian Reservoir Management Center was a subordinate unit of the agency, responsible for flood control, irrigation, urban water supply management, and other work.

Time and reason of Three Gorge reservoir's clear water storage
The Three Gorge Reservoir was usually cleared during the autumn and winter. The main reasons for the Three Gorge Reservoir's water storage were as follows: 1. Most of China's climate was monsoonal, so there was less rainfall in winter compared to other seasons. Little or no water entered the reservoir, which was conducive to the reservoir's storage. 2. There was less rain in winter, so water storage could ensure navigation and power generation, as well as the discharge flow during the dry season, and the flood control pressure in winter was small. 3. During the flood season, the silt content in the Yangtze River was relatively high. During the transition between autumn and winter, although the water volume was still large enough to fill up the storage capacity of the Three Gorge, the silt content was relatively small compared to earlier. If the silt content in the Yangtze River was higher, it would be easier for the reservoir to be silted up if it was stored. Therefore, it was chosen to store water at this time.
