TheKuoyka orKuoika (Russian:Куойка;Yakut:Куойка) is a river inYakutia (Sakha Republic),Russian Federation. It is atributary of theOlenyok with a length of 294 kilometres (183 mi) and a drainage basin area of 4,750 square kilometres (1,830 sq mi).[1] The Kuoyka flows north of theArctic Circle across a lonely, desolate area of theOlenyoksky District devoid of settlements.[2]
The name of the river comes from theNganasan word"kuoika", (куойка), meaning ahousehold deity.[3]
The Kuoika is a left tributary of the Olenyok. Its sources are at the limit of theNorthern Siberian Lowland, off the northeastern end of theCentral Siberian Plateau.[4] It flows roughly eastwards to the southwest and south of theBeyenchime in an area with numerous lakes. In its last stretch the Kuoika turns in a SSE direction entering the Central Siberian Plateau area. It meanders strongly in its southernmost section within a wide gorge until it meets the left bank of the Olenyok 473 km (294 mi) from its mouth.[2][5][6]
The river is frozen between early October and early June.[4] Its main tributary is the 169 kilometres (105 mi) longSektelyakh from the right. Other tributaries are much shorter, such as the 42 kilometres (26 mi) long Kuchchugui-Kuoyka, the 39 kilometres (24 mi) long Kusagan-Khayalakh and the 36 kilometres (22 mi) long Oyur from the left.[1]
The last, tortuous stretch of the river was described in such terms by Yuri Tsenin inVokrug sveta:
Its channel bends so whimsically in a wide canyon that sometimes one can't understand in which direction it flows. We are surrounded by lemon-yellow mountains. The shores of the Kuoika rise above the water as a fortified wall with odd-looking towers and ramparts.[7]
