Biya, River in Altai Republic, Russia
The Biya is a river flowing through the Altai region for about 301 kilometers, starting from Lake Teletskoye and heading toward the Katun River. The river moves through a wide valley with forested banks and scattered settlements along its course.
The river became important during Russian expansion eastward into Siberia, with the town of Biysk established at its lower reach in 1709. The waterway gradually transformed into a key passage for trade and settlement movement into the far eastern territories.
The river sustains local communities along its banks by providing fish and fresh water, shaping how people live in this region of southern Siberia.
The river can be navigated during warmer months, though it freezes over from mid-November through early April. Checking local conditions and speaking with boat operators is wise before planning any water-based visits.
Where the Biya meets the Katun River near Biysk, the two streams merge to form the start of the Ob River, one of Asia's largest river systems. Many visitors pass through the area without realizing they are at the meeting point of these major waterways.
