Core Viewpoint - Dongying City is implementing a modernized reservoir management matrix to enhance water resource management and operational efficiency, focusing on digital empowerment, systematic governance, practical science, and sustainable effectiveness [3][5]. Group 1: Digital Empowerment - The Gaodian Reservoir developed an integrated model for "regulation and storage control," achieving a stable annual water supply of 53 million cubic meters, with a supply guarantee rate increasing from 85% to 95% and a 40% improvement in dispatch plan accuracy [4]. - The Yongzhen Reservoir established the province's first "smart patrol" scenario, enhancing patrol efficiency by 60% and saving over 500,000 yuan in annual operational costs through 3D simulation, video monitoring, and electronic fencing [4]. Group 2: Systematic Governance - Dongying City innovated a "full-chain integrated" operation and maintenance model, reducing annual maintenance costs by over 1 million yuan and increasing equipment availability from 80% to 98% [5]. - The Gaodian Reservoir collaborated with academic institutions to create a routine mechanism for seepage monitoring and safety evaluation, improving the timeliness of safety hazard detection by 50% [5]. Group 3: Practical Science - The Gaodian Reservoir constructed a dual evaluation model for benefits and safety, reducing water transfer costs by 12% and providing scientific support for dam safety assessments [6]. - The Yongzhen Reservoir developed a dual rehearsal model for "water transfer and reservoir charging," increasing water utilization efficiency by 10% and achieving a win-win situation for economic and ecological benefits [6]. Group 4: Sustainable Effectiveness - A closed-loop mechanism for hazard investigation and rectification was established at the Yongzhen Reservoir, ensuring dynamic clearance of potential hazards [7]. - The Gaodian Reservoir formulated a "Safety Operation Manual," incorporating data on water levels and seepage for daily monitoring, ensuring traceability of data, risk management, and accountability [7]. - As of now, the two pilot reservoirs have improved water supply capacity by 15%, reduced operational costs by 30%, and achieved a 20% increase in comprehensive benefits, while overcoming three major technical bottlenecks in intelligent scheduling, professional operation, and benefit integration [7].

Core Insights - The article highlights the successful management and ecological restoration of the Ersheng Reservoir, emphasizing its role in water supply and environmental protection [1][2][3] Group 1: Water Management and Supply - The Ersheng Reservoir has a total capacity of 57.2 million cubic meters and is crucial for irrigating 11,000 acres of farmland and providing water for over 100,000 residents [1] - Due to drought conditions, the reservoir's capacity decreased by approximately 5 million cubic meters, leading to a water replenishment of about 3.1 million cubic meters over 24 days starting from April 14 [1] Group 2: Infrastructure and Safety - The reservoir has completed hazard mitigation works, with the dam rated as a "Class I dam," ensuring stable operation of its spillway and water conveyance structures [2] - The implementation of an automated monitoring system allows for real-time tracking of water levels, water quality, and structural conditions, maintaining a water quality standard of Class II with a 100% compliance rate [2] Group 3: Ecological and Community Impact - The reservoir's management under the "River Chief System" has improved flood control capabilities and promoted ecological restoration, leading to a thriving ecosystem that attracts various bird species and enhances local biodiversity [2] - The area has become a popular recreational spot for residents and tourists, contributing to the local economy and community engagement [2][3]
