The Lungkha (Russian: Лунгха; Yakut: Луҥха, Luŋxa) is a river in Yakutia (Sakha Republic), Russia. It is the 14th longest tributary of the Lena with a length of 508km (316miles) —533km (331miles) counting its Yychaky tributary. Its drainage basin area is 10300km2.
A331 highway passes close to the river near its origin. The villages of Oyun-Unguokhtakh, Argas and Taas-Tumus are located by the river. The last 72km (45miles) stretch of the Lungkha is navigable.[1]
The Lungkha is a left tributary of the Lena. It is formed at the confluence of the Yychaky and Yulagir rivers in the northern part of the Lena Plateau. It flows in a roughly northeastern direction nearly parallel to the Tyugyuene to the east. In its middle course it descends into the Central Yakutian Lowland where it meanders within a wide floodplain parallel to the lower course of the Vilyuy further north. Finally it meets the left bank of the Lena 1132km (703miles) from its mouth and 30km (20miles) upstream from the mouth of the Vilyuy. The river basin is fed by rain and snow. Floods are common in the summer period.[1] [2] [3]
The largest tributaries of the Lungkha are the 87km (54miles) long Tokhoron and the 315km (196miles) long Khatyng-Yuryakh, both from the right. The river freezes between October and May.[1] [3] [4] [5]
The vegetation of the Lungkha basin is marked by middle taiga landscape. The snow cover in the river basin lasts an average of 220 days yearly.
The main fish species in the river are pike, ide and perch.[1]
