Existing conditions of Wanfeng Lake

In the past two years, with the rapid development of tourism development, sewage discharge from cities and factories in the upper reaches of the reservoir area, and the blind flooding of a large number of fisheries, etc., have caused serious damage to the ecology of Wanfeng Lake and the degree of eutrophication of the water body. It is becoming increasingly serious, with total nitrogen exceeding the standard by 2 to 3.8 times on average, total phosphorus exceeding the standard by 2.6 to 11.4 times on average, and ammonia nitrogen exceeding the standard by 7.9 times on average. The eutrophication of water bodies has caused harmful aquatic plants to multiply rapidly. From below the exit of Lubuge Power Station and below the Lubuge Pier of Wanfeng Lake, there are endless water hyacinths and water lilies. The beautiful and pleasant lakes and mountains in the past have been replaced by green pollutants. replaced. From 2002 to now, water hyacinth and water hyacinth have occupied more than 1,000 acres of the lake, posing serious threats to the aquaculture, shipping, production and life of immigrants in the reservoir area, and creating great safety risks.

At present, due to the lag in ecological management work, the ecological disasters in Wanfeng Lake are still intensifying, especially the spread of water lilies. The problem is quite prominent, covering almost all harbors, seriously threatening the navigation safety of ships.
