The Arga-Yuryakh (Russian: Арга-Юрях; Yakut: Арҕаа Үрэх, Arğaa Ürex) is a river in Sakha Republic (Yakutia), Russia. It is one of the major tributaries of the Omoloy. The river has a length of 214km (133miles) and a drainage basin area of 5530km2.
The river flows north of the Arctic Circle, across desolate tundra territories of the East Siberian Lowland. Its basin falls within Ust-Yansky and Bulunsky districts. The name of the river comes from the Yakut "Arğaa-ürex" (Арҕаа-үрэх), meaning "western river".[1]
The Arga-Yuryakh is a left tributary of the Omoloy. It has its sources at the confluence of the 50km (30miles) long Mundukan and the 38km (24miles) long Khadarynnya in the eastern slopes of the Orulgan Range of the Verkhoyansk Range system. The river flows roughly in an ENE direction and when it descends into the East Siberian Lowland, it bends and heads in a NNE direction until the end of its course. In its last stretch the river flows roughly parallel to the Omoloy further east, meandering in the floodplain. Finally the Arga-Yuryakh bends to the east and joins the left bank of the Omoloy 190km (120miles) from its mouth. The confluence is 89km (55miles) downstream of the mouth of the Kuranakh-Yuryakh.[2] [3] [4]
The main tributaries of the Arga-Yuryakh are the 25km (16miles) long Ulakhan-Kieng-Appa on the right, as well as the 85km (53miles) long Turkulaakh, the 63km (39miles) long Tonguulaakh, the 43km (27miles) long Alyy-Yurege, the 29km (18miles) long Omukchaan, the 98km (61miles) long Yullyugen and the 64km (40miles) long Mas-Khayippyt on the left. The river is frozen between early October and early June. There are more than 1,500 lakes in its basin.[5]
