The municipal water affairs bureau has announced that the downstream of Miyun Reservoir will add approximately 36 kilometers of river sections with water. Various surface water sources including Miyun Reservoir, Baihebao Reservoir, Yaoqiaoyu Reservoir, and Beitaishang Reservoir in the Chaobai River Basin have been used to start the multi-path ecological water replenishment combining main and tributary streams. In total, the replenishment capacity of Miyun Reservoir is regarding 40 million cubic meters. The Miyun Reservoir opened the gates of the Baihe Power Station in the direction of Baihe and replenished water to the Chaobai River Basin through three paths. The replenishment will last approximately two months and is part of an effort to promote groundwater conservation and the recovery of the ecological environment of the Chaobai River. The water affairs department will closely track the replenishment process, optimize dispatching measures according to each river’s actual flow conditions, and dynamically adjust the replenishment flow to ensure the flow of the Chaobai River is not less than 50 days in the Beijing section. This will form an effective supply for the Mihuaishun groundwater reserve area and further promote the coordinated restoration of the surface and underground of the Chaobai River Basin.

News from our newspaper (Reporter Wang Tianqi) Yesterday, the Municipal Water Affairs Bureau jointly dispatched surface water sources such as Miyun Reservoir, Baihebao Reservoir, Yaoqiaoyu Reservoir, and Beitaishang Reservoir in the Chaobai River Basin, and started the multi-path ecological water replenishment combining main and tributary streams. Among them, the total replenishment capacity of Miyun Reservoir is regarding 40 million cubic meters.
At 9 o’clock yesterday, the Miyun Reservoir opened the gates of the Baihe Power Station in the direction of Baihe, controlling the flow rate to 2.5 cubic meters per second, and replenishing water to the Chaobai River Basin through three paths, with a planned replenishment of 14 million cubic meters. The first path is to replenish water to the main channel of the Baihe River through the flood discharge sluice of the Baihe Regulating Pool. The flow rate is controlled at 1 cubic meter per second, and 5.5 million cubic meters of water will be replenished; the second path is to replenish water to the Shahe River in Miyun District through the Miyun Reservoir Regulation and Storage Project. , the flow rate is 0.5 cubic meters per second, and 3 million cubic meters of water will be replenished; the third path is to enter the Jingmi Diversion Canal through the Gongzhuangzi Sluice Gate to the Lishishan Diversion Gate, and replenish water to the Xiaozhong River. 5.5 million cubic meters.
At 10 o’clock yesterday, the Chaohe Water Transport Tunnel of the Miyun Reservoir was also opened to replenish water to the Chaohe River.
The spring ecological replenishment of the Chaobai River aims to continue to promote the groundwater conservation of the Mihuaishun water source and the recovery of the ecological environment of the Chaobai River. The replenishment is expected to last for regarding two months. During the period of ecological water replenishment, in line with the working principle of making good use of limited water resources, the water affairs department will closely track the water replenishment process, optimize dispatching measures according to the actual flow conditions of each river, and dynamically adjust the replenishment flow, striving to realize the flow of Chaobai River in the Beijing section The duration is not less than 50 days, and a 36-kilometer river section with water is newly added below the Miyun Reservoir. While providing a strong water source guarantee for the ecological recovery along the Chaobai River, and creating a good habitat for animals and plants to thrive in spring, it will also form an effective supply for the Mihuaishun groundwater reserve area, and further promote the coordinated restoration of the surface and underground of the Chaobai River Basin.

In conclusion, the multi-path ecological water replenishment project in the Chaobai River Basin, which was kicked off yesterday, is a positive step towards conserving groundwater and improving the ecological environment in the region. The project will provide a strong water source guarantee for the ecological recovery along the Chaobai River and create a good habitat for animals and plants to thrive in spring. Additionally, it will form an effective supply for the Mihuaishun groundwater reserve area, thereby promoting the coordinated restoration of the surface and underground of the Chaobai River Basin. The two-month-long replenishment is expected to last and will result in the addition of a newly rejuvenated 36-kilometer river section below the Miyun Reservoir. The water affairs department is closely tracking the water replenishment process and will dynamically adjust the replenishment flow to ensure the flow of Chaobai River in the Beijing section is not less than 50 days. Overall, this initiative is a commendable effort in ensuring access to clean water and protection of aquatic ecosystems in the region.
