Quick Summary

The Hrazdan River is a significant waterway in Armenia, primarily known as a tributary of the Aras River. The Aras River itself originates in Turkey and flows eastward, forming a substantial part of the international border between Armenia and Azerbaijan to the north, and Turkey and Iran to the south. The Hrazdan River plays a crucial role in irrigating much of Armenia and is notable for draining Lake Sevan, with the Hrazdan being the only river to flow out of the lake. Armenia's rivers are generally short and turbulent, with considerable hydroelectric potential due to significant elevation changes along their courses.12
