[4] The Korkodon basin is a desolate area; there are no settlements, but since the lower reaches of the river are navigable; timber rafting was carried out in the 20th century.

Halfway through its course it bends and flows west and then southwestwards, fringing the Yukaghir Highlands.

Finally the river joins the right bank of the Kolyma 1,228 km (763 mi) from its mouth at an elevation of 93 m (305 ft).

There are over 1,100 lakes in the Korkodon basin, most of them of the thermokarst type (alas), as well as swamps.

[5] Among the fish species found in the river Arctic char, pike, sucker, lenok and whitefish deserve mention.
