Eyik (Russian: Эйик; Yakut: Ээйик, Eeyik) is a lake in the Sakha Republic (Yakutia), Russia. It is the largest lake in Olenyoksky District.[1]
Lake Eyik provides a habitat for the Siberian Crane, a Critically Endangered species.
Eyik is located in the eastern part of the Central Siberian Plateau. Located at southern end of Olenyoksky District. Eyik village lies near the northern lakeside.[2]
Lake Eyik is almost round in shape. There are a few small islands in the southwestern area of the lake, not far from the shoreline. The outflow of the lake is a left tributary of the Tyukyan, a river of the Lena basin, flowing from the southern shore in a southeastern direction.[1] The sources of river Tyukyan are in a large wooded swamp to the west of the lake.[3]
