The Yarenga (Russian: Яренга) is a river in the Ust-Vymsky District of the Komi Republic and in the Lensky District of the Arkhangelsk Oblast in Russia. It is a right tributary of the Vychegda. The river is 281km (175miles) long, and its drainage basin covers 5140km2. The principal tributaries are the Vezhay (left) and Uktym (right). The Yarenga is the main river of the Lensky District north of the Vychegda and collects virtually all the drain of that area.
The source of the Yarenga is near the village of Vezhayka in the Komi Republic. The Yarenga flows to the north-west through primeval pine and larch forests, enters the Arkhangelsk Oblast, and in the village of Yarenga turns south-west. It is noted for its many rapids. In the village of Ust-Ocheya, where it accepts the Ocheya from the left, it turns south-east. Yarensk is on the left bank, approximately 3km (02miles) from the river course. The Yarenga empties into the Vychegda about 5km (03miles) downstream from Yarensk.
Fossils ot temnospondyl amphibians Parotosuchus komiensis, Yarengia perplexa, Batrachosuchoides ochevi and Melanopelta antiqua were found in the Lower Triassic (Upper Olenekian) deposits, near this river.[2]
