Tosu Lake and Kruk Lake are collectively called Tabu Lake. It is a famous pair of twin lakes, one salty and one light, known as the "Lake of Lovers", with beautiful legends. Tosu Lake is located in the south of Lake Kruk. Its water intake is from Lake Kruk. It is a closed lake, salty salt accumulation, water is microalkali, and it is a salt water lake. On the water surface of 4.6 and 6.1 kilometers away, there are two islands with an area of 13 hectares and 370 hectares. The lake is surrounded by a Gobi sand beach. Tosu Lake is a saltwater lake, so it is in stark contrast to Keluke Lake, surrounded by almost no plants, the lake is blue and blue! The lake is surrounded by vast Gobi beaches, with high temperatures, large evaporation of the lake, high salt content in the water, and few aquatic and phytoplankton plants and animals. In addition to the sparse reeds and a small number of plankton in the lake, there are almost no water plants, and there are sporadic white thorns, strange willow, salsa and other plants around the lake. Tosu Lake is vast and the lake shore is open and unobstructed. When the wind is calm, the lake is smoke and smoke, the water and the sky are the same, and the wind is spectacular; when the weather changes, the lake is rough, the waves splash, and the shore is sounded, which is exciting. In the early spring of each year, fish fins, brown head fins, wild ducks and so on come to the bird island in Tosu Lake to gather. Tosu Lake Bird Island covers an area of about one square kilometer, and there are thousands of birds on the island. The whole island nests and eggs are full of birds. It is simply a "bird paradise" and "egg world".
