Group 2: Responsibilities and Coordination - There is a call for enhanced accountability in flood defense, with daily assessments and a focus on optimizing work deployment to improve the effectiveness and timeliness of flood prevention measures [1]. - The need for strengthened monitoring, forecasting, and early warning systems is highlighted, particularly in response to heavy rainfall, to support decision-making and timely alerts [1]. Group 3: Water Resource Management - The article stresses the importance of scientifically managing reservoir operations, balancing flood safety with water storage needs, and optimizing the dispatch plans for key reservoirs like the Three Gorges and Danjiangkou [1]. - There is a directive for local areas to enhance inspections and defenses of riverbanks and to manage risks associated with small rivers and reservoirs, particularly those that are vulnerable or under construction [1]. Group 4: Safety and Quality Assurance - Ensuring the safety of the Danjiangkou Reservoir and its water quality is a priority, with ongoing monitoring and analysis of flood data to enhance engineering and water quality safety capabilities [2]. - The article also mentions the importance of public communication and media engagement to promote flood defense measures and operational effectiveness, fostering a supportive public opinion environment [2].

Group 1 - Recent heavy rainfall in the Huaxi region has led to significant water level increases in small rivers in Chongqing, with some reaching record highs for the year [1][5] - On October 13, the water level of the Mudixi River in Yunyang County peaked at 300.42 meters, marking the highest level since the onset of the flood season [1] - The local water resources department has implemented measures such as coordinated flood discharge from hydropower stations and increased monitoring to ensure public safety [1][3] Group 2 - The Ministry of Water Resources reported that the autumn flood season this year is characterized by frequent heavy rainfall, high cumulative rainfall, and many rivers exceeding warning levels [5][7] - Since late August, there have been nine significant rainfall events affecting the autumn flood area, with cumulative rainfall in the Haihe and Yellow River basins reaching record highs since 1961 [5][7] - A total of 130 rivers across several provinces have experienced floods exceeding warning levels, with notable occurrences in the Yellow River and its tributaries [7] Group 3 - The overall flood defense situation in the Yangtze and Yellow River basins is complex and severe, with predictions of additional rainfall events in the coming week [7][9] - The Ministry of Water Resources has deployed strategies for flood defense, including precise scheduling of reservoirs to mitigate flood pressure in the middle and lower reaches of the Yellow River [9] - Efforts are being made to ensure that key reservoirs, such as the Danjiangkou and those in the Yangtze River basin, reach full storage capacity to manage potential flooding [9]

Core Viewpoint - The Ministry of Water Resources predicts that the middle reaches of the Yellow River and its tributaries, as well as the Yangtze River's tributaries, will experience 1 to 2 rainfall events in the coming week, leading to potential flood risks in certain areas [1] Group 1: Flood Prevention Measures - The Ministry has deployed flood prevention measures for the autumn flood season in the Yangtze and Yellow River basins, emphasizing the need for scientific and precise management of water reservoirs [1] - Specific actions include the careful regulation of the Fenhe Reservoirs to alleviate flood pressure in the middle and lower reaches of the Yellow River [1] - In the Han River basin, unified management of reservoir groups is crucial to prevent excessive flooding in the middle and lower reaches [1] Group 2: Reservoir Management - The management of the Danjiangkou Reservoir and upstream reservoirs will be conducted in an orderly manner to ensure full storage capacity is achieved [1] - For the Yangtze River, the sequence of reservoir operations will be scientifically determined to prevent excessive flooding in the middle and lower reaches [1] - The goal is to ensure that the Three Gorges and upstream control reservoirs reach full storage capacity [1]
