Hrazdan River
The Hrazdan River is the second longest river in Armenia and the most significant tributary of the Aras River within the country. It originates at the northwestern tip of Lake Sevan and flows approximately 141 kilometers southward through the Kotayk Province and the capital city, Yerevan, before joining the Aras. The river is a cornerstone of the Armenian economy, primarily due to the Sevan-Hrazdan Cascade, a series of seven hydroelectric power plants constructed during the Soviet era for power generation and large-scale irrigation. The Hrazdan Gorge in Yerevan is a prominent geological feature characterized by basalt columns and serves as a vital green space within the urban landscape. Historically, the river has been crucial for the development of the region, as its waters irrigate the fertile Ararat plain. Ecologically, the Hrazdan faces challenges from industrial runoff and the heavy withdrawal of water from Lake Sevan, which are now managed through strict government regulations. It remains an essential artery for agriculture, industry, and recreation in central Armenia.
