Ura (Lena)

The Ura (Ура), also known as Kamenka (Каменка) and Uksakan (Уксакан), is a river in Yakutia (Sakha Republic), Russia. It is a tributary of the Lena with a length of 181 km and a drainage basin area of 2830 km2.

The river flows across an uninhabited area of the Olyokminsky District.

Course
The Ura is a left tributary of the Lena. It has its sources in the Lena Plateau, to the southeast of the course of the Ergedey, the main tributary of the Derba. The river heads in a roughly southwestern direction across taiga wooded areas with scattered lakes. In its lower course it encounters a hilly area where it first bends west, and then again to the southwest, meeting the Lena 2366 km from its mouth, 29 km southeast of the mouth of the Derba.

The mouth of the Ura, having a picturesque knoll rising above it, is a tourist attraction regularly visited by river cruisers Demyan Bedny and Mikhail Svetlov. The Ura freezes yearly between October and May.

Fauna
Pike, burbot and sander are found in the waters of the Ura.
