Core Viewpoint - The Baihebao Reservoir serves as a crucial water source for Beijing, delivering high-quality water and playing a significant role in flood control and regional water resource management [1][3]. Group 1: Water Supply and Quality - From 2021 to 2025, Baihebao Reservoir is expected to supply 789 million cubic meters of Class II quality water to key reservoirs in Beijing, equivalent to the volume of 39 Kunming Lakes [1]. - The reservoir maintains a consistent Class II water quality throughout the year, ensuring reliable water supply [3]. Group 2: Flood Control and Management - The reservoir acts as a flood control barrier, utilizing a closed-loop mechanism of "forecast-warning-pre-release-regulation" to optimize water usage [3]. - In 2024, proactive measures will be taken to lower water levels before the flood season, ensuring adequate space for floodwater retention [3]. Group 3: Cross-Regional Collaboration - Baihebao Reservoir has established a joint prevention and control mechanism with Zhangjiakou's water authority, enhancing information sharing and water resource management [3]. - During the 2025 flood season, the reservoir successfully managed an inflow of 16.321 million cubic meters of upstream water, setting a new record for water distribution [4]. Group 4: Ecological and Social Benefits - The water supply efforts have led to ecological improvements, such as maintaining the ecological flow of the Guishui River and supporting the revival of local wetlands and wildlife [4]. - The groundwater level in the region has risen by 2.55 meters over five years, contributing to the recognition of Guishui River as a "Happy River" in Beijing [4].
