Coco Suri Lake is located in Fuyun County, Altai District, and can be seen on the way to the Coco To Sea Scenic Area. Coco Suri Lake is also known as the "Wild Duck Lake", which is famous for the increase of wild ducks due to the migratory birds staying here in autumn. The lake is small in size, about 2 square kilometers, with an average depth of 2 meters, and there are more than 20 floating islands in the lake, covered with reeds. Lake Coco Suri was formed after the 1981 earthquake.
