Original title: Miyun Reservoir has a record water storage capacity of 3.371 billion cubic meters and will provide water to the downstream in a timely manner
As of 8 o’clock on August 24, the Miyun Reservoir had stored 3.371 billion cubic meters of water, exceeding the historical record set in 1994. The municipal water affairs department will, based on the principle of “safety and more water storage”, make overall plans for flood control and water resources dispatch, and provide water to the downstream in a timely manner.
Historical data show that on September 16, 1994, the Miyun Reservoir reached its maximum water storage capacity of 3.358 billion cubic meters, and the water level reached a record high of 153.98 meters. To this end, the Miyun Reservoir Management Office built a black stone monument engraved with the “highest water level in history” beside the Baihe Wharf. However, since 1994, the reservoir has never reached the maximum water level.
Since the flood season began in 2021, the Beijing Water Affairs Department has made full use of the favorable conditions of more rainfall in the Miyun Reservoir basin under the premise of ensuring the safety of flood control, combined with storage and stagnation, and precise scheduling, so that the water storage capacity of the Miyun Reservoir has continued to increase. As of 15:00 on August 23, the water storage capacity of Miyun Reservoir has reached 3.359 billion cubic meters, breaking the highest record in history. At 8 o’clock in the morning on August 24, the Miyun Reservoir had a water storage capacity of 3.371 billion cubic meters, and the water level had exceeded the bottom of the stele.
The relevant person in charge of the Municipal Water Affairs Bureau said that due to rainfall and natural runoff, the water level of the Miyun Reservoir is still rising slowly. “Although the water storage capacity is large, it is still in the flood season, and ensuring the safety of flood prevention is the first.” The municipal water affairs department will follow the principle of “safety and more water storage” to make overall plans for flood control and water resources dispatch. Replenish water is dispatched downstream through the Chaohe and Baihe Rivers in a timely manner.
As the capital’s strategic water resources reserve base, Miyun Reservoir will continue to operate at a relatively high water level for a long period of time in the future. The water affairs department stated that it will fully summarize and draw on the historical experience of Miyun Reservoir’s high water level operation, formulate a new period of Miyun Reservoir high water level operation plan, continue to promote the construction of the smart Miyun Reservoir, encrypt monitoring, detection, forecasting and analysis, strengthen overall scheduling, and ensure safety during floods and safety. run.
In addition, in order to implement the requirement of “hiding water in the ground”, the water affairs department will strengthen strategic groundwater reserves, coordinate the relationship between water storage, water supply and flood control of the Miyun Reservoir, and combine the management requirements of the reservoir’s flood limit water level to ensure safety in a timely and appropriate manner. The amount of water discharged, carry out ecological water replenishment in the Chaobai River Basin, speed up the construction of the city’s strategic groundwater reserve base and the ecological restoration of the river basin.
