Hydrology and Water Systems
Lake Baikal’s hydrology is marked by its great depth, unique water purity, and an intricate exchange of inflowing rivers and outflow through a single channel. Its water volume, exchange processes, and scientific significance make it a unique point of study in limnology.
Origin and Flow of the Angara River
The Angara River is the only outflow from Lake Baikal. It emerges from the southern tip of the lake, near the city of Listvyanka. Over 300 rivers and streams feed into Baikal, but the Angara is the sole exit, making its flow crucial for maintaining water balance.
Baikal’s water level is largely regulated by the Angara’s outflow, which is controlled by a hydroelectric station near Irkutsk. This results in stable seasonal changes and prevents major flooding or drought conditions around the lake. The Angara eventually joins the Yenisei River, playing a critical role in Siberia’s river network.
Comparison with Great Lakes
Lake Baikal holds more water than all of North America’s Great Lakes combined. Its maximum depth reaches about 1,642 meters, making it the deepest lake on Earth. The Great Lakes, while larger in surface area, are much shallower by comparison.
