Alymdya

The Alymdya (Алымдя o Алымджа; Алымдьа), is a river in Yakutia (Sakha Republic), Russia. It is a right hand tributary of the Akhtaranda, part of the Vilyuy basin. The river is 227 km long and has a drainage basin of 5310 km2.

The Alymdya flows across an uninhabited sector of Mirninsky District.

Course
The Alymdya belongs to the upper stretch of the Vilyuy basin. It originates in the southeastern Vilyuy Plateau. The river heads roughly southeastwards and then southwards, crossing a cluster of small lakes and swamps. Then it turns southeastwards again and keeps roughly that direction until its mouth at the confluence with the 191 km long Olguydakh from the left to form the Akhtaranda, 75 km from its mouth in the Vilyuy Reservoir.

Tributaries
The main tributaries of the Alymdya are the 50 km long Kurakkalyr (Кураккалыыр) from the right and the 66 km long Alymdya-Tuorata (Алымдьа-Туората) from the left. The river freezes in mid October and stays under ice until the second half of May.
