Yanranaygytgyn (;) is a freshwater lake in Iultinsky District, Chukotka Autonomous Okrug, Russian Federation.[1] It has an area of 10.6km2 and a catchment area of 75.9km2.
There are no permanent settlements on the shores of the lake.[1]
The name of the lake in Chukot means "a lake near a separate mountain."[2]
Yanranaygytgyn is located in the Chukotka Mountains, 35km (22miles) to the south of Ervynaygytgyn. The lake has a roughly triangular shape and there are three islands in the middle. The southern shore is indented and the lake narrows towards its northern end.[3]
Yanranaygytgyn lies in an area of lakes at the northern edge of the Amguema Valley. It is the largest of the cluster, together with lake Kontalyagytgyn that lies 5km (03miles) to the southwest. An unnamed river, a small tributary of the Amguema, flows out of the lake from the northern end. Yanranaygytgyn freezes in mid-September and stays under ice until June.[4]
Yanranaygytgyn is surrounded by tundra. Arctic char is common in the waters of the lake.[5]
