Orotko

Orotko is a great freshwater lake on the Yana–Indigirka lowland north of the Arctic Circle. Its basin owes its form both to tectonic movement and the thawing of frozen ground. Several streams enter the lake, while the Togusta and Chubuku leave its eastern shore for the Chondon. Tundra and wetlands surround the waters, which ultimately drain toward the Laptev Sea.
