Lake Sevan's Water Level Drops by 2 cm in a Week but Remains Higher Than Last Year

According to data from the Hydrometeorology and Monitoring Center of Armenia, the surface elevation of Lake Sevan stood at 1900.72 meters above sea level as of August 16. This figure is 15 centimeters higher than the measurement recorded on the same day last year. Notably, the current water level already exceeds the target indicator set for January 1, 2026, by a margin of 50 centimeters.

Water Inflow Dynamics

The transfer of water into the lake via the Arpa-Sevan aqueduct—a critical tunnel designed to maintain the lake's ecological balance—is ongoing. Between August 10 and 16 alone, 1.701 million cubic meters of water flowed into the lake. Looking at the broader picture, the total volume of water transferred through this route from the beginning of the year up to August 16 has reached 167.156 million cubic meters.

Water Releases and Overall Picture

Parallel to the inflows, controlled water withdrawals are being carried out to meet agricultural and energy needs. According to data from the Geghamavan observation post, 10.835 million cubic meters of water were released through the derivation channel of the Hrazdan Hydroelectric Power Plant (HPP) between August 10 and 16. Cumulatively, from July 2 to August 16, the total volume of water discharged from Lake Sevan amounted to 41.368 million cubic meters.
