Core Viewpoint - The Three Gorges Reservoir experienced its largest flood event of 2025 on September 20, influenced by autumn rains in Western China, while managing water resource utilization and flood safety [1][3]. Group 1: Flood Management - The Three Gorges Reservoir's inflow increased significantly, exceeding 40,000 cubic meters per second on September 20, following multiple rounds of rainfall in the upper reaches of the Yangtze River [3]. - To ensure flood safety, the Three Gorges Group reduced the reservoir's water level to a minimum of 162.6 meters by increasing the outflow to 25,300 cubic meters per second during the flood peak [3]. Group 2: Water Resource Utilization - The reservoir's total inflow from July to August was over 20% lower than the average since its establishment, indicating a prolonged dry spell in the upper Yangtze region [3]. - Following the approval of the water storage plan by the Ministry of Water Resources on September 10, the Three Gorges Reservoir began to store water while coordinating with flood control measures [3]. Group 3: Future Monitoring and Control - The Three Gorges Group will closely monitor upstream water forecasts to manage reservoir water levels effectively, ensuring flood safety while progressing with the annual water storage goals [3].

Group 1 - The company achieved significant progress in its three main businesses: comprehensive water resource development, clean energy development and operation, and ecological environmental protection and energy-saving services, successfully completing over half of its annual targets in the first half of the year [1] - The water resource segment delivered 20.43 billion cubic meters of water, achieving 53.4% of the annual plan, with significant progress in pipeline installation and investment in the southern central region of the province [1] - The clean energy sector integrated 300,000 kW of hydropower and 200,000 kW of wind power, generating 450 million kWh, which is 57% of the annual target, with ongoing projects in wind power and compressed air energy storage [1] Group 2 - The ecological environmental protection business made steady progress, with successful project completions including the equipment update for the Benxi High-tech Zone sewage treatment plant and the completion of the reclaimed water project at the Liaodong Bay Second Sewage Treatment Plant [2] - By the end of June, the company completed an annual investment of 1.316 billion yuan, with strategic emerging industries seeing a 60.96% year-on-year increase in investment [2] - The overall labor productivity reached 664,000 yuan per person, reflecting a year-on-year growth of 3.6% [2]

Group 1 - The current flood season poses significant challenges for flood prevention tasks in many areas, with some regions neglecting flood control efforts during small watershed management, leading to safety hazards and adverse impacts on local flood prevention work [1] - Small watershed management is a comprehensive and systematic project, where flood prevention during the flood season is crucial for the safety of people's lives and property, as well as the effectiveness and long-term stability of the entire management project [1] - Flood prevention should not be conducted in isolation but should be integrated with various measures such as water conservancy law enforcement, ecological restoration, soil and water conservation, and comprehensive water resource utilization [1] Group 2 - Small watersheds often have significant topographical variations and uneven surface coverage, leading to rapid runoff formation after rainfall, which can trigger sudden disasters like flash floods and mudslides [2] - During small watershed management, it is essential to consider the natural geographical features and historical hydrological data of the watershed to design appropriate drainage systems, flood control dams, and diversion channels [2] - Establishing and improving real-time monitoring and early warning systems for rainfall, water conditions, and disasters is crucial for timely information collection, transmission, and analysis to support emergency responses [2] Group 3 - To ensure the long-term effectiveness and systematic nature of flood prevention efforts, it is necessary to strengthen institutional frameworks and technological support [3] - A sound regulatory framework and responsibility mechanism for small watershed management should be established, clarifying the flood prevention responsibilities of various government levels, relevant departments, and social entities [3] - The introduction of modern information technologies, such as remote sensing monitoring, geographic information systems (GIS), and artificial intelligence prediction models, can enhance the scientific and intelligent level of flood prevention decision-making [3]

Group 1 - The core viewpoint of the article emphasizes the comprehensive promotion of river protection and management, highlighting the need for integrated water resource utilization and the development of hydropower, pumped storage, and inland shipping [1] - The document outlines significant achievements in China's water resource utilization, including the Baihetan Hydropower Station's cumulative power generation exceeding 196 billion kilowatt-hours, which equates to saving over 59 million tons of standard coal and reducing carbon dioxide emissions by over 160 million tons [1] - The article notes the rapid growth of inland shipping, with the annual cargo volume on the Yangtze River increasing from less than 2 billion tons to over 3.5 billion tons in the past decade, leading the global inland shipping sector [1] Group 2 - The continuous improvement of the policy framework provides solid support for comprehensive water resource utilization, with the 2021 plan aiming to establish a modern pumped storage industry by 2035 to meet the demands of high-proportion renewable energy development [2] - The article identifies challenges in policy coordination and market mechanisms, such as unreasonable water rights allocation and high costs of advanced technology, which hinder effective water resource management [2] - It suggests that integrating policy drivers with market mechanisms can unlock the potential for comprehensive water resource utilization, emphasizing the need for strict water resource management assessments and diversified financing channels [2] Group 3 - The article discusses the importance of technology and innovation in enhancing water resource utilization, advocating for targeted research and the application of advanced technologies like nanofiltration and smart water meters [3] - It highlights the necessity of breaking down administrative barriers and establishing collaborative governance mechanisms across regions and departments to optimize water resource management [3] - The focus is on achieving scientific allocation and efficient use of water resources in agriculture, industry, and urban settings through effective measures [3]
