175米，第14次实现蓄满目标！三峡水库为今冬明春“水安全”奠定坚实基础

Core Points - The Three Gorges Reservoir has achieved its 2025 goal of reaching a water level of 175 meters, with an effective storage capacity of 22.15 billion cubic meters, marking the 14th time since 2010 that this target has been met [1][2] - Reaching the 175-meter level is crucial for ensuring sufficient water resources during the dry season, as over 60% of the annual inflow occurs during the flood season [6][4] - The reservoir's management has effectively utilized a digital twin system for precise water level control, balancing water storage and flood safety [14][12] Group 1 - The 175-meter water level is the maximum operational height for the Three Gorges Reservoir, essential for flood control and water resource management in the Yangtze River basin [2][4] - The reservoir's ability to reach this level significantly alleviates flood pressure on downstream areas, ensuring a stable water supply for both ecological and human needs [4][8] - From November last year to April this year, the reservoir released a total of 11.67 billion cubic meters of water to downstream areas, equivalent to a year's water supply for over 15 million people [6][8] Group 2 - The management of the reservoir involved coordinated operations among 58 control reservoirs in the Yangtze River basin, emphasizing the complexity of water storage and release strategies [10][16] - The water management team has been monitoring real-time data to optimize water flow, especially during periods of reduced inflow from upstream [8][14] - The effective storage capacity of the control reservoirs has surpassed 100 billion cubic meters, setting a new historical record and providing robust water source assurance for the upcoming dry season [16][17]
