Abstract

Reservoirs are core water conservancy infrastructure for regional water resource regulation, flood control, disaster reduction, irrigation and water supply. Their safe and stable operation is a key support for ensuring the sustainable development of regional economy and society, maintaining ecological environment balance and avoiding water disaster risks. Taking 35 small and medium-sized reservoirs in Pingliang City as the research object, relying on official statistical data, reservoir safety appraisal reports and engineering operation and maintenance (O&M) ledgers from 2016 to 2025, this paper systematically judges the current characteristics and core bottlenecks of the safe operation of reservoirs in Pingliang City by means of literature research, empirical analysis and induction, and analyzes the causes of problems from four dimensions: natural endowment, engineering construction, O&M management and fund guarantee. Combined with the objective needs of regional water resource endowment and water conservancy development, a targeted optimization path is constructed. The research shows that Pingliang City has achieved remarkable results in improving flood control capacity and promoting standardized O&M of reservoirs, but problems such as aging and attenuation of engineering facilities, insufficient regulation and storage capacity, and low level of information monitoring are still prominent. The collaborative measures proposed in this study, including engineering renovation, intelligent empowerment, management improvement and fund expansion, can effectively build a strong line of defense for the safe operation of reservoirs, and provide theoretical reference and practical paradigm for the safety governance of small and medium-sized reservoirs in arid and semi-arid areas of Northwest China.

1. Introduction

1.1. Research Background

Pingliang City is located in the eastern part of Gansu Province, belonging to a typical arid and semi-arid climate zone. The region is scarce in water resource endowment, with uneven spatial and temporal distribution of precipitation, frequent soil and water loss, and high pressure on flood and drought disaster risk prevention and control. As the core hub of regional water resource optimal allocation and disaster prevention and mitigation system, reservoirs play an irreplaceable role in regulating runoff, reducing flood peaks, ensuring water supply and improving ecology

[1]

. By the end of 2020, Pingliang City had built 35 small and medium-sized reservoirs in total, including 2 medium-sized reservoirs and 33 small-sized reservoirs, with a total storage capacity of 194 million cubic meters, covering 7 counties (cities and districts) of the city. They undertake the core functions of water supply for more than 1.85 million rural population, irrigation for 470,400 mu of farmland and flood control and disaster reduction in key areas

[1]

. In recent years, Pingliang City has gradually promoted key projects such as reservoir danger removal and reinforcement, and mountain flood disaster prevention, and continuously improved the flood control O&M system. However, affected by the superposition of multiple factors such as long construction age, intensified natural erosion and limited O&M conditions, potential safety hazards in some reservoirs have not been completely eradicated, and the stability of engineering operation and comprehensive efficiency are restricted, making it difficult to fully meet the high-quality development needs of regional water security guarantee and ecological environment protection

[2-5, 16-18]

With the in-depth advancement of water resource security strategy and the implementation of regional water conservancy development planning, the safe operation of reservoirs has become an important part of the construction of water security guarantee system. It is necessary to carry out targeted research based on empirical data to solve the problems of reservoir O&M governance and improve the comprehensive operation efficiency of reservoirs. In this context, focusing on the current situation of the safe operation of small and medium-sized reservoirs in Pingliang City, identifying core problems through empirical analysis, analyzing deep-seated causes and putting forward optimization countermeasures have important practical value for improving the regional water security guarantee system, promoting the sustainable utilization of water resources, and supporting the coordinated development of ecological environment protection and rural revitalization.

1.2. Research Significance

Enrich the empirical research results on the safety governance of small and medium-sized reservoirs in arid and semi-arid areas of Northwest China, construct a systematic research framework of "current situation diagnosis - cause analysis - countermeasure optimization", fill the gap in regional targeted research, and provide ideas and theoretical support for the research on the safe operation of reservoirs under similar climatic and geographical conditions

[8, 9, 14]

. Accurately identify the weak links in the safe operation of reservoirs in Pingliang City, construct an optimized governance plan suitable for the regional reality, provide a scientific basis for the regional water conservancy competent departments to carry out reservoir O&M management, hidden danger remediation and efficiency improvement, help build a strong regional water security barrier, and promote the coordinated development of water resource utilization with economic society and ecological environment.

1.3. Research Methods and Data Sources

1.3.1. Research Methods

This paper adopts a multi-method integrated research idea to ensure the scientificity and rigor of the research: (1) Literature research method: systematically sort out relevant research results at home and abroad on reservoir safety O&M, flood control scheduling optimization and water conservancy engineering governance, and learn from advanced governance theories and practical experience to lay a theoretical foundation for the research. (2) Empirical analysis method: relying on the reservoir engineering O&M ledgers, safety appraisal reports and flood control scheduling monitoring data of Pingliang City, quantitatively analyze the current situation and core problems of reservoir safe operation to enhance the empirical support of the research. (3) Induction method: extract the common characteristics and individual problems of the safe operation of reservoirs in Pingliang City, analyze the deep-seated causes of the problems, and construct a targeted optimization countermeasure system to ensure the practicability and pertinence of the research conclusions

[10, 12]

1.3.2. Data Sources

The data used in this paper are all from official public materials and field monitoring data to ensure the authenticity, reliability and integrity of the data and provide a solid support for empirical research: (1) Public materials of industry competent departments: including water conservancy development plans, annual engineering O&M reports and reservoir safety appraisal results issued by the Water Conservancy Bureau of Pingliang City

[1, 2, 11]

. (2) Flood control and disaster prevention monitoring data: including reservoir hidden danger investigation ledgers, emergency disposal records and performance monitoring data of flood control responsible persons published by flood control and drought relief monitoring institutions in all counties (cities and districts) of Pingliang City

[3, 5, 15]

. (3) Engineering field monitoring data: including reservoir storage capacity curve review data, dam safety monitoring data, termite and other dike-damaging organism control and renovation data, and water supply statistics

[2, 6, 7, 13]

. (4) Provincial industry monitoring bulletins: monitoring bulletins on flood control and disaster prevention and safety operation assessment of water conservancy projects in Pingliang City issued by the Emergency Management Department of Gansu Province

[5]

. The data cover the period from 2016 to 2025, comprehensively covering the whole process of reservoir engineering construction, O&M management, scheduling regulation and emergency disposal.

2. Empirical Analysis on the Current Situation of Safe Operation of Reservoirs in Pingliang City

2.1. Basic Overview of Reservoirs

The existing 35 small and medium-sized reservoirs in Pingliang City are all distributed in the main regional basins such as Jinghe River, Huluhe River, Heihe River and Ruihe River. Among them, the medium-sized reservoirs include Kongtong Reservoir (with a storage capacity of 29.7 million cubic meters) in Kongtong District and Wangxiakou Reservoir in Huating City. The typical small-sized reservoirs include Dongxia Reservoir in Jingning County and Dengjiachuan Reservoir in Lingtai County (with a total storage capacity of 2.05 million cubic meters)

[3, 7]

. In terms of construction age, more than 70% of the reservoirs were built in the 1970s and 1980s, and only a few reservoirs were newly built or upgraded in recent years. In terms of functional positioning, most reservoirs are comprehensive water conservancy projects with multiple functions such as flood control, irrigation and water supply, and some small-sized reservoirs are mainly for single irrigation or flood control. Among them, Zhujiajian Reservoir in Jingchuan County (with a total storage capacity of 3.035 million cubic meters) can guarantee domestic water for 103,100 residents and irrigation demand for 9,000 mu of farmland

[6]

By 2025, Pingliang City has completed the safety appraisal and provincial verification of 5 medium-sized reservoirs, implemented 11 reservoir danger removal and reinforcement projects and 1 special reservoir maintenance project, completed the control and renovation of termite and other dike-damaging organisms in 24 small-sized reservoirs, and managed 1,022.06 kilometers of dikes, gradually improving the basic guarantee capacity for the safe operation of reservoirs

[2]

. At the same time, the city has built a two-level (municipal/district and county) mountain flood disaster monitoring and early warning information platform, realizing full coverage of reservoir flood control responsibilities, and a total of 3,863 flood control O&M responsible persons at all levels have been implemented

[5]

The type, quantity and storage capacity distribution of 35 small and medium-sized reservoirs in Pingliang City are shown in Table 1, which clearly presents the scale and structure characteristics of regional reservoirs and provides basic support for the subsequent analysis of safe operation.

Table 1. Statistics of Small and Medium-Sized Reservoirs in Pingliang City.

Reservoir Type	Quantity (units)	Proportion (%)	Total Storage Capacity (10,000 m³)	Main Distribution Basins	Typical Reservoirs
Medium-sized Reservoirs	2	5.7	3,520	Jinghe River, Ruihe River	Kongtong eservoir, Wangxiakou Reservoir
Small-sized Reservoirs	33	94.3	15,880	Jinghe River, Huluhe River, Heihe River	Dongxia Reservoir, Dengjiachuan Reservoir, Zhujiajian Reservoir
Total	35	100	19,400	Main Regional Basins	/

2.2. Achievements in Safe Operation

2.2.1. Significant Improvement in Flood Control and Disaster Reduction Capacity

Since 2016, Pingliang City has implemented 9 sections of important tributaries of rivers such as Jinghe River and Huluhe River and 23 sections of small and medium-sized river management projects, with a total of 207.56 kilometers of river dikes managed. By 2025, the total length of managed river dikes in the region has reached 1,010.5 kilometers

[1]

. At present, the flood control standard of the central urban section of Jinghe River in Pingliang has reached 50-year return period, and the urban river sections of the other 6 counties (cities) have all reached 20-year return period

[1]

. In the pre-flood investigation in 2025, a total of 37 reservoirs and small ponds and dams were investigated, 9,720 meters of river channel dredging was completed, 22,800 cubic meters of silt and debris were removed, 71 potential safety risks of various types were rectified, and closed-loop elimination of hidden dangers was realized

[5]

. Kongtong Reservoir and Dongxia Reservoir have completed the review of storage capacity curves, significantly improving the accuracy of flood control scheduling. The regional reservoir flood control work has gradually transformed from passive emergency disposal to active precise prevention and control

[1, 2]

2.2.2. Continuous Optimization of Standardized O&M Level

Pingliang City has gradually promoted the standardized creation of reservoirs. In 2024, Kongtong Reservoir in Kongtong District passed the acceptance of standardized creation, and Dongxia Reservoir in Jingning County started the standardized creation after the completion of the danger removal and reinforcement project

[2]

. By 2025, the management and protection scope delimitation of 4 reservoirs (Tuniu, Wugao, Xianghe, Yabian) in Jingning County and Anzishan Barrage has been completed, and the delimitation results of 2 key flood control reservoirs have been put on record

[2]

. At the same time, the regional directory of dikes and sluices has been established and improved, the review of the maximum discharge capacity of 148 sluices in the system has been completed, the processes and standards for daily inspection and maintenance of reservoirs have been standardized, and the O&M management of reservoirs has been promoted to transform to standardization

[2]

2.2.3. Steady Enhancement of Water Supply Guarantee Efficiency

Through the implementation of supporting projects for drought-resistant emergency water sources, Pingliang City has built 8 drought-resistant emergency water source projects such as Nanyuan in Jingchuan and Sanhuagou in Chongxin, and continuously promoted the upgrading and transformation of reservoir water supply supporting facilities

[1]

. After the operation of new reservoirs such as Dengjiachuan Reservoir, the annual water supply volume reaches 1.3185 million cubic meters, which can guarantee the production and domestic water demand of 108,000 residents; Zhujiajian Reservoir has an annual water supply volume of 2.14 million cubic meters, effectively making up for the shortcomings of regional water supply guarantee

[6, 7]

. By the end of 2020, the rural tap water supply population in Pingliang City has reached 1.8535 million, and the coverage rate of rural drinking water safety has reached 100%. The core supporting role of reservoirs in the regional water supply guarantee system has become increasingly prominent

[1]

2.3. Main Problems

2.3.1. Aging Facilities and Declining Regulation Capacity

Among 33 small reservoirs, 25 (75.8%) have structural hazards: dam seepage, spillway damage and aging pipelines. Long-term operation and siltation reduce storage capacity, failing to meet flood control and water supply demands. Lack of regular dredging further reduces flood storage and increases flood risk.

2.3.2. Low Informatization and Poor Scheduling Accuracy

Only 5 medium-sized reservoirs have real-time monitoring; small reservoirs mainly rely on manual patrol with low efficiency and large errors. Scheduling depends on experience; no scientific flood control–utilization coordination model is established, which is inconsistent with intelligent development.

2.3.3. Weak O&M Force and Imperfect Management

Small reservoirs are scattered; most have only 1–2 part-time staff without professional skills. Aging personnel lack ability in equipment operation and hidden danger detection. The “three principals” system is implemented but with weak performance, non-standard records and insufficient emergency capacity.

2.3.4. Insufficient Funding and Lack of Long-Term Mechanism

In 2024, only 1.0542 million yuan of central funds was allocated for termite control, covering only 24 small reservoirs. Funding is “focused on medium and large, neglecting small”. Danger removal and informatization projects lag behind; no long-term “construction–O&M–maintenance–renewal” mechanism is formed.

3. Causes of Reservoir Safety Problems

3.1. Fragile Ecology and High Disaster Risk

Frequent soil erosion, concentrated rainfall and flood-season storms cause dam scouring and siltation. Arid climate and large evaporation lead to long-term low water level, accelerating dam cracking and pipeline aging. Termites and other pests damage 24 small reservoirs and over 1,000 km of dikes.

3.2. Low Construction Standards and Lagging Renovation

Reservoirs built in the 1970s–1980s had low standards and inherent defects. Although some danger removal projects were carried out, most small reservoirs lack comprehensive upgrading; partial renovation cannot fundamentally improve stability.

3.3. Imperfect System and Weak Supervision

There is a disconnect between municipal planning and county implementation; grass-roots institutions and professional teams are inadequate. Supervision of daily inspection and maintenance is insufficient; work is formalized without closed-loop management. Staff training is insufficient, failing to meet intelligent and standardized requirements.

3.4. Single Funding Channel and Unbalanced Allocation

Funds mainly depend on central and provincial finance; local supporting capacity is limited. Lack of social capital participation leads to a single investment structure. Funds tilt to large and medium-sized reservoirs, leaving small reservoirs underfunded.

4. Optimization Countermeasures for Reservoir Safe Operation

4.1. Strengthen Engineering Renovation

4.1.1. Danger Removal, Reinforcement and Dredging

Prioritize danger removal and reinforcement of high-hazard small reservoirs, focusing on dam seepage and spillway repair. Establish annual silt inspection and regular dredging to restore design capacity. Standardize downgrade and decommissioning of unsafe reservoirs (Xianghe, Wangjiagou) to eliminate risks.

4.1.2. Improve Supporting Facilities

Upgrade water supply and irrigation pipelines and channels. Renovate spillways and sluices to meet flood control standards in Jinghe and Huluhe basins. Strengthen dike and sluice maintenance to improve river–reservoir flood control coordination.

4.2. Promote Intelligent Empowerment

4.2.1. Build Information Monitoring System

Invest in rainfall, water regime and safety monitoring; build county-level smart water platforms to realize real-time monitoring of 35 reservoirs. Apply IoT and big data to build an intelligent management platform for early warning and dynamic control. Improve the mountain flood early warning system for full coverage.

4.2.2. Optimize Collaborative Scheduling

Build a “forecast–simulate–decide–warn” scheduling model and multi-scale flood routing model for coordinated flood control and utilization. Evaluate flood impacts, formulate hierarchical early warning schemes and improve storage efficiency. Regularly review storage capacity curves.

4.3. Improve Management System

4.3.1. Perfect Mechanism and Team

Building Establish a “municipal coordination, county responsibility, township implementation, village cooperation” system; include reservoir management in performance assessment. Equip full-time staff for small reservoirs and carry out professional training. Realize full standardization of O&M.

4.3.2. Compact Responsibilities and Strengthen Emergency Response

Strictly implement the “three principals” system with public list, clear standards and regular assessment. Improve flood control plans and conduct at least 2 practical drills annually. Stock emergency materials and establish a rapid rescue mobilization mechanism.

4.4. Broaden Funding Channels

4.4.1. Increase Financial Input and Optimize Allocation

Strive for central and provincial special funds; increase local investment. Prioritize danger removal, informatization and maintenance. Increase funding for small reservoirs and strengthen fund supervision

[15, 16]

4.4.2. Guide Social Participation

Introduce social capital through government purchase service and franchise. Establish a “public participation + government subsidy” mechanism. Integrate water conservancy and ecological funds to form a diversified investment pattern.

4.5. Strengthen Ecological Governance

Implement watershed ecological management and soil erosion control to reduce siltation. Expand termite control coverage and consolidate results. Strengthen water body protection, regulate pollution and promote reclaimed water reuse to improve water quality.

Table 2. Implementation Framework of Optimization Countermeasures.

Core Problems	Main Causes	Countermeasures
Aging facilities, declining capacity	Natural erosion, low standards, lagging renovation	Danger removal, regular dredging, supporting facilities
Low informatization, poor scheduling	Insufficient funds, lack of models	Monitoring system, scheduling model optimization
Weak O&M, imperfect management	System disconnect, poor training	Mechanism improvement, team building, responsibility compaction
Insufficient funding, no long-term mechanism	Single channel, unbalanced allocation	Diversified funding, optimized allocation
Ecological hazards, serious siltation	Soil erosion, pest damage	Watershed governance, pest control

5. Conclusion and Prospect

5.1. Conclusion

AB  - Reservoirs are core water conservancy infrastructure for regional water resource regulation, flood control, disaster reduction, irrigation and water supply. Their safe and stable operation is a key support for ensuring the sustainable development of regional economy and society, maintaining ecological environment balance and avoiding water disaster risks. Taking 35 small and medium-sized reservoirs in Pingliang City as the research object, relying on official statistical data, reservoir safety appraisal reports and engineering operation and maintenance (O&M) ledgers from 2016 to 2025, this paper systematically judges the current characteristics and core bottlenecks of the safe operation of reservoirs in Pingliang City by means of literature research, empirical analysis and induction, and analyzes the causes of problems from four dimensions: natural endowment, engineering construction, O&M management and fund guarantee. Combined with the objective needs of regional water resource endowment and water conservancy development, a targeted optimization path is constructed. The research shows that Pingliang City has achieved remarkable results in improving flood control capacity and promoting standardized O&M of reservoirs, but problems such as aging and attenuation of engineering facilities, insufficient regulation and storage capacity, and low level of information monitoring are still prominent. The collaborative measures proposed in this study, including engineering renovation, intelligent empowerment, management improvement and fund expansion, can effectively build a strong line of defense for the safe operation of reservoirs, and provide theoretical reference and practical paradigm for the safety governance of small and medium-sized reservoirs in arid and semi-arid areas of Northwest China.
