Sevan is the biggest natural reservoir in Armenia (RA) and in South Caucasus, one of the biggest mountain lakes in the world. The problem of the lake appeared in last century due to usage of its water resources for irrigation and power production, and this problem was partly solved. There is Sevan-Hrazdan hydro-economic complex, which includes a cascade of hydro-power plants (with total capacity of 556 MW) constructed on Hrazdan River, which flows out of Lake Sevan. The complex also includes irrigation systems for 80’000 hectares of lands in Ararat Valley.
