Orotko Lake

Lake Orotko spreads across the western Yana–Indigirka lowland beyond the Arctic Circle. Its freshwater basin was shaped by both tectonic movement and the thawing of frozen ground. The Kepppekhtyakh and other streams flow into it, while the Togusta River and Chubuku channel leave from the eastern shore to join the Chondon. Beyond the low shores lie tundra, marshes and many smaller lakes.
