Since 2008 the process of increasing Lake Sevan level has been
suspended based on different reasons and substantiations.
- Under estimates, a total of 9,325 (5.20 + 4.125) billion cum water
flew into Lake Sevan (746 cm of water level), out of which 2.303
billion cum through "Arpa-Sevan" tunnel.
- A total of 2.067 billion cum water was let out of lake for irrigation
and other purposes (under data by Haypethydromet Service).
- Factually, 4.565 (3.10+1.465) billion cum water was collected in
the lake (365 cm of water level), which is twice as much as the water
volume flown into Lake Sevan through "Arpa-Sevan" tunnel.
- In the first six years, the average level increase of the lake
water was maximum 69 cm, in the second six years - 55 cm.
- In the second six years as compared with the first six years,
1.075 (5.20-4.125) billion cum less water flew into the lake, out
of which 0.519 (1.411-0.892) billion cum through "Arpa-Sevan" tunnel
in 20011-13.
