Sededeme

The Sededeme flows across northeastern Yakutia to join the Kolyma from the left. Also known as the Fedotikha, it gathers the waters of a landscape of lakes and northern woodland. Its waters contain an important spawning ground for muksun, a valuable whitefish of the Arctic river systems. The Kolyma carries the river's waters onward through the lowlands toward the East Siberian Sea.
