Namucuo lake, the highest saltwater lake in China, is 4718 meters above sea level

Namucuo is the highest saltwater lake in China and in the world.

Namucuo lake is 4718 meters above sea level and approximately rectangular in shape. It is more than 70 kilometers long from east to west and more than 30 kilometers wide from north to south, covering an area of 1920 square kilometers.

Namco Lake is a closed lake with little precipitation and strong sunshine in the lake area. The only way out of the lake is evaporation, with an annual evaporation of 2.304 billion cubic meters. There are two ways to enter the lake: the lake water is mainly supplied by natural precipitation and high mountain ice melting snow. One part is the melting water of glaciers in the flow field, and the other is the runoff formed by rainfall on the total area of the basin.

According to the calculation, the glacier melt water entering the lake is 124 million cubic meters / year, the precipitation runoff is 1.334 billion cubic meters / year. According to the annual rainfall of 410 mm, the water directly falling on the lake surface is 787 million cubic meters / year. The total annual inflow of the above two items is about 2.256 billion cubic meters. According to the above data, the annual water inflow and outflow of Namco are basically balanced, and the water exchange period of the lake is 34.15 years.
