Quick Facts Seymchan Сеймчан, Location ...

The name comes from the Yakut language word Kheymchen, which is an area of open water surrounded by sea ice.[3]

Course

The river rises in the Upper Kolyma Highlands, eastern limits of the Chersky Range, at the confluence of Left Seymchan and Right Seymchan. It flows first in a northeast direction, bending along its course until it flows in a southeastern direction. Finally it meets the Kolyma near Seymchan, 158 km (98 mi) from its mouth, downstream from the mouth of the Buyunda on the opposite bank.[4]

Together with the Buyunda that flows roughly northwards on the other side of the Kolyma basin, the Seymchan forms the Seymchan-Buyunda Depression, which limits the Upper Kolyma Highlands from the east.[5]

Its main tributaries are the Medvezhya and the Verina.
