Yenisey

The Yenisey is a major river system in Russia and Mongolia, flowing northwards across Siberia and emptying into the Arctic Ocean. It is the largest river system in Russia by drainage basin and the second-largest by discharge, surpassed only by the Lena River. The Yenisey originates in the mountains of Tuva, in southern Siberia, near the Mongolian border, and flows for approximately 3,487 kilometers (2,167 miles) to the Kara Sea.

The river's drainage basin is vast, covering over 2.5 million square kilometers (970,000 square miles). Its main tributaries include the Angara, the Podkamennaya Tunguska, and the Nizhnyaya Tunguska. The Yenisey is navigable for much of its length, particularly the lower reaches. Major cities located on its banks include Krasnoyarsk, Abakan, and Igarka. The river is a crucial transportation route and plays a significant role in the region's economy, supporting hydroelectric power generation, fishing, and timber rafting. The climate in the Yenisey basin is predominantly continental, with long, cold winters and short, warm summers. The river freezes over for several months each year.
