Recently, under the guidance of the Ministry of Water Resources, the Yunnan Provincial Department of Water Resources issued the "Comprehensive Management Plan for Nine Plateau Lakes in Yunnan Province into Lakes". The "Plan" proposes engineering governance measures from five aspects including water area shoreline management and protection, flood control, water resource protection, water ecological protection and restoration, and water environment monitoring. 152 engineering projects are planned to be implemented with a total investment of 8.291 billion yuan, of which The investment is 6.066 billion yuan, and the other investment is 2.225 billion yuan.

According to the person in charge of the Yunnan Provincial Department of Water Resources, most of the water supplied to the lake and the pollutants entering the lake area enter the lake through the rivers entering the lake. The amount of water entering the lake and the quality of the water are the main factors that determine the quality of the lake. An important starting point for lake protection and management is to manage and control the rivers entering the lake.

Implemented 152 engineering projects

The "Planning" clearly states that the key research objects of this planning are based on the main lake-inlet (outlet) rivers identified by each Huzhou (city) involved, included in the management of the river chief system and regularly monitored for water quality, including the main lake-inlet rivers of the nine plateau lakes There are 124 river courses, 6 of which are mainly out of the lake. The current base year is 2020, the near-term level year of the plan is 2025, and the long-term outlook is 2035. The governance principles are ecological priority and green development; comprehensive planning and key points; comprehensive policy implementation and systematic governance; step-by-step implementation to ensure effectiveness. With the goal of achieving "smooth rivers, clear water, green banks, and beautiful scenery", we will define the management scope of rivers entering the lake, improve weak links in flood control, ensure the amount of clean water entering the lake, improve water quality entering the lake, improve the appearance of the water environment, and restore water ecology. Comprehensive and systematic planning should be carried out in terms of improving the monitoring system, making up for shortcomings in monitoring and monitoring facilities, and establishing and improving a long-term mechanism for river management, and propose targeted governance goals and tasks for each lake.

The "Plan" proposes engineering governance measures from five aspects. In terms of the shorelines of lakes and rivers, it is clear to accelerate the promotion of 17 demarcation projects that have not yet delineated the scope of river management and protection, and 58 projects that have marked the scope of river management and protection. In terms of flood control, on the basis of comprehensively clarifying the flood control standards for the rivers entering the lake, it is proposed to improve the embankment of 40 rivers, dredge 56 rivers, prevent and control mountain torrent disasters in the upper reaches of 32 rivers, and remove 17 dangerous sluices and 32 dangerous reservoirs. Reinforcement of risks, improvement of urban flood control and drainage capacity. In terms of water resources protection, 38 rivers and rivers have been proposed to salvage and clean up garbage and floating debris, and 12 rivers and water systems have been connected and ecological water replenishment projects have been proposed. In terms of water ecological protection and restoration, 20 river channel ecological comprehensive management, 18 river source area water and soil conservation and water source conservation ecological construction, and 2 water beauty village pilot construction projects were proposed. In terms of water environment monitoring, it includes the construction of 58 water quality monitoring stations, 123 hydrological monitoring stations and 190 video surveillance system construction projects.

The "Plan" also formulated the delineation of the management and protection scope of rivers entering the lake and the implementation of signs, the investigation and improvement of water intakes, the investigation and improvement of river outlets, the daily inspection and cleaning of rivers, the diversion of rain and sewage in urban areas, and the improvement of sewage treatment plants. There are 12 management and control measures including quality improvement and efficiency improvement and utilization of tail water resources, improvement of flooded points in urban river sections, rural sewage collection and treatment, prevention and control of agricultural non-point source pollution, improvement of quality and efficiency of river wetlands, and law enforcement and supervision.
