The Seymchan (Russian: Сеймчан) is a river in Srednekansky District, Magadan Oblast, Russia. It is a left tributary of the Kolyma, with a length of 158 kilometres (98 mi) a drainage basin of 3,600 square kilometres (1,400 sq mi).[1][2]
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.
