Reservoir safety operation regulations serve as critical technical documents for standardizing regulation practices, ensuring the safe and stable operation of reservoir, and maximizing the comprehensive benefits. Currently, with changes in hydrological conditions within river basins, reforms in management system, and heightened ecological conservation demands, traditional regulations are increasingly showing limitations in adaptability, such as inefficient multi-stakeholder coordination and delayed emergency response procedures. Aiming at this, taking the compilation of regulation guidelines for Dahuofang reservoir in Liaoning province as a case study, this paper explains the background and basis for compilation of regulation guidelines for large-scale reservoirs, systematically outlines the core content of the guidelines, and constructs a scientific framework covering multi-objective regulation, characteristic parameter adaptation, management mechanisms, and division of rights and responsibilities. As well, the key relationships that require balancing during the compilation process are analyzed, such as flood control versus water utilization, water supply versus ecological needs, and the demands of different users. At the same time, based on the actual situation of the management system reform and functional expansion of Dahuofang reservoir, this paper explores challenges and optimization directions for modern regulation development—such as dynamic adjustments and refined scheduling—providing theoretical support and practical references for standardizing and dynamically optimizing similar large reservoir regulations, and contributing to achieving the integrated regulation objectives of "safety and controllability, optimal benefits, and ecological friendliness."

In recent years, frequent extreme rainfall events have posed growing threats to the flood control safety of dams. Pumped storage dams are typically located in the upper reaches of mountainous rivers or narrow valleys, featuring small reservoir capacities and limited catchment areas. These conditions often lead to rapid flood rise and recession, while the lack of measured hydrological data increases the sensitivity of design flood estimates to extreme precipitation. Focusing on registered and recorded pumped storage dams, this study analyzes their current flood control safety status. Based on these analyses, and considering the operational characteristics of different pumped storage station types, the flood control safety risks and challenges are categorized and summarized, providing references for conducting flood control risk assessments, evaluating dam safety, and improving specialized emergency response plans for pumped storage dams.
