Kelimyar

The Kelimyar (Келимяр Кэлимээр, Kelimeer) is a river in Yakutia (Sakha Republic), Russia. It is a tributary of the Olenyok with a length of 254 km and a drainage basin area of 4050 km2.

The river flows north of the Arctic Circle across a desolate area of Bulunsky District devoid of settlements. The nearest inhabited places are Taymylyr, located downstream from its confluence with the Olenyok, and Sklad (Tyumyati), located a little upstream.

History
In 1875, during his third Siberian expedition, Alexander Chekanovsky intended to "go along the banks of the Lena to the mouth and, if possible, then go to the mouth of the Olenyok from the Laptev Sea."

From a barge Chekanovsky navigated the Lena River for a distance of about 1200 km from Yakutsk to the mouth to the Eyekit river, its last major left tributary. He explored inland from the deep and wide lower course of the Eyekit, and then along the rocky and mountainous watershed area lying between the Lena and the Olenyok, descending along the Kelimyar river to the Olenyok. In this way he discovered the roughly 350 km long ridge that bears his name. From the Kelimyar he traced the course of the Olenyok to its mouth.

Course
The Kelimyar is a right tributary of the Olenyok. Its sources are in a small lake of the western slopes of the Chekanovsky Ridge. It flows first in a roughly southern direction in its upper course, then it bends northwestwards heading in that direction within a low floodplain with marshes and many small lakes. It meanders strongly in stretches until it joins the right bank of the Olenyok river 186 km upstream of its mouth.

Owing to the harshness of the climate the river is frozen between early October and early June.

Tributaries
The longest tributaries of the Kelimyar are the 51 km long Muoykanda-Yurege and the 44 km long Khotugu-Muoykanda-Yurege from the right, as well as the 70 km long Nyoyokyu, the 66 km long Olongdo, the 39 km long Mene, the 37 km long Amyday, the 36 km long Bulungkaan-Yurege and the 30 km long Kystyk-Khaya-Yurege from the left.
