Yenisei-Angara River System

Yenisei-Angara River System, stretching 5,539 km through Siberia, is one of the world's longest and most pristine rivers. Originating in Mongolia's Khangai Mountains, the Yenisei merges with the Angara near Russia's Lake Baikal (Earth's deepest lake) before emptying into the Arctic Ocean. A vital Arctic freshwater source, it supports tundra ecosystems and migratory fish like sturgeon. Despite hydropower dams (e.g., Sayano-Shushenskaya), its remote taiga and permafrost landscapes remain wild. A lifeline for indigenous communities, it symbolizes Siberia’s untamed grandeur.
