Why is the water in Kanas opaque and emerald green?

Kanas Lake is called "Discoloration Lake". In spring and summer, the lake will change color with the change of season and weather. From the opening of the lake in April and May to the closure of the lake by snow and ice in June165438+1October, the lake presents different colors in different seasons. In the lake in May, the ice and snow melted, and the lake was dark and blue-gray; In June, the lake turned green with the plants in Zhoushan, showing light green or blue; After July, it was a flood period, and the white lake in the upper reaches of the white lake was replenished in large quantities, changing from bright green to milky white with blue-green color. In August, the lake was affected by rainfall and was dark green; 10 in September and June, the water supply of the lake was obviously reduced, the surrounding plants were colorful, and a pool of green lake was dazzling. The reason for the discoloration of lake water is the increase of mineral components in the upper reaches of the river caused by seasonal changes; It is also related to the different colors reflected by the plants on the surrounding mountains in the lake with seasonal changes, as well as the changes of sunlight angle in different seasons and the influence of illumination and action on the lake. Kanas Lake mainly comes from Kanas Glacier on the south slope of Friendship Peak. When the glacier acts on the surrounding mountain composed of light-colored granite, the granite blocks carried by the glacier excavation are squeezed and ground into white fine powder and mixed in the ice layer. In hot summer, the glaciers with white powder melt, and a large amount of milky glacier melt water and rainwater enter Kanas River and flow into Akkule Lake (White Lake). The milky water of Akkule Lake flows down the river and flows into Kanas Lake, which is called Kanas Lake. After freezing in June+February in 5438 every year, Kanas Lake looks like a white crystal mirror, and local herders use sledges to transport goods or ski and skate on the lake. In addition, when Kanas is viewed from different angles in different weather, the special water quality reflects different colors with the sky and mountains. Because Kanas Lake is surrounded by mountains, under the background of blue sky and white clouds on the plateau, the lake is reflected by sunlight and clouds, and the surrounding mountains are also reflected in the lake. The lake will change with the changes of clouds in the sky and the brightness of mountains in the sun, and it will be colorful.
