Finally it meets the Lena  from its mouth near Biryuk village and  downstream from the mouth of the Cherendey. The largest tributary of the Biryuk is the  long Melichan (Меличан) that joins it from the right. There are lakes in its basin, including relatively large Ebye Kyuel. The river freezes yearly between October and May. See also
