Chybyda

The Chybyda (Чыбыда; Чыбыыда) is a river in Yakutia (Sakha Republic), Russia. It is a right hand tributary of the Vilyuy, with a length of 451 km and a drainage basin area of 9960 km2.

The river flows across practically uninhabited territory of Vilyuysky District. Its confluence with the Vilyuy lies approximately 30 km upstream from Vilyuysk.

Course
The Chybyda begins in the southern sector of the Lena Plateau. It flows roughly in a northward and northwestward direction along most of its course. After it descends into the Central Yakutian Lowland it meanders strongly. Finally it joins the right bank of the Vilyuy 365 km from its mouth. The river is fed by snow and rain. It freezes in mid October and stays under ice until the second half of May.

Tributaries
The Chybyda has some very long tributaries, such as the 229 km long Byrykan (Бырыыкаан) and the 114 km long Sergelyakh (Сергелях) from the left, as well as the 193 km long Tymtaidakh (Тымтайдах) from the right.
