The Uel-Siktyakh is a right
tributary of the Lena. It has its origin in the slopes of the
Dzhardzhan Range, on the western flank of the
Orulgan Range, northern
Verkhoyansk Range system. The Uel-Siktyakh is formed at the confluence of the Yras-Siktyakh and Daldyndya rivers. It flows first roughly northwestwards. After leaving the mountains it bends and heads northeastwards across a floodplain. Towards the end it
meanders strongly in a swampy area of the
Central Yakutian Lowland dotted with lakes. Finally it bends westwards and joins the right bank of the Lena from its mouth, upstream of the mouth of the
Kuranakh-Siktyakh. The longest tributaries of the Uel-Siktyakh are the Atyrkan and the long Oymyakon, both from the right. ==See also==
