The Khatyngnakh is a left tributary of the Uyandina. It is formed by the confluence of the  long Donskaya from the left and the  long 2nd Nonchondzhya (2-я Нонгонджя) from the right, both rivers having their sources in the southern slopes of the Polousny Range range. The Khatyngnakh flows meandering roughly southwards across a vast floodplain in the northern sector of the Aby Lowland, where there are innumerable lakes and swamps. Finally the river joins the left bank of the Uyandina  from its mouth in the Indigirka. Tributaries
