Pangong Lake, which means "long-necked swan" in Tibetan, is located about 12 kilometers northwest of Ritu County, Ali Prefecture, and runs east-west. With an average altitude of 4400 meters, the lake is light in the east and salty in the west, about 15 kilometers away from Ritu County. It is a natural lake ecological scenic tourist attraction. The entire lake area is 604 square kilometers. The average width from north to south is about 4 kilometers, the narrowest point is only 5 meters, the average water depth is 5 meters, and the maximum water depth is 41 meters.

Pangong Lake is a typical river lake. The long and narrow body of Pangong Lake creates a unique landscape effect. The two largest tributaries that flow into Pangong Lake, Maga Zangbo and Domaqu, are both located in the eastern section of the lake. The sources of freshwater are sufficient, the supply is greater than the evaporation, and the salinity of the lake is maintained within 0.75 g/L. so that the eastern section of the lake is a freshwater lake; while the freshwater supply in the middle and western sections has dropped sharply, and the narrowest part of the lake in the middle section is only 100-150 meters wide, and the lake water in the east-west direction is not smooth. Supplementing to the west makes the evaporation of the western lake larger than the replenishment and the salinity of the lake increases from the middle to the west to nearly 20 g/L, turning it into a saltwater lake.
