Lake Sevan is the largest body of water in Armenia and the Caucasus region. It is one of the largest freshwater high-altitude (alpine) lakes in Eurasia. The lake is situated in Gegharkunik Province, at an altitude of 1,900 m (6,234 ft) above sea level. The total surface area of its basin is about 5,000 km2 (1,900 sq mi), which makes up 1⁄6 of Armenia's territory.The lake itself is 1,242 km2 (480 sq mi), and the volume is 32.8 km3 (7.9 cu mi). It is fed by 28 rivers and streams. Only 10% of the incoming water is drained by the Hrazdan River, while the remaining 90% evaporates.
The lake provides some 90% of the fish and 80% of the crayfish catch of Armenia.Sevan has significant economic, cultural, and recreational value. Its sole major island (now a peninsula) is home to a medieval monastery.
Due to the high altitude the climate during the summer is very gentle and warm, best time for tourists to visit Sevan. Lake Sevan looks fabulous in photos but nothing compares to seeing the lake with your own eyes.
