The negative balance of Lake Sevan will lead to sharp worsening of the water quality, the head of the Association "For stable development", Karine Danielyan, told Arminfo correspondent.
According to assessment of Hydroecology Centre under Emergency Situations Ministry of Armenia, at the end of 2014, a negative balance 9-12 sm will be fixed at the Lake Sevan because of unfavorable climate and weather conditions.
The tendency of decrease of the level of Sevan will have negative consequences, she said. "It means decrease of transparency and oxygen content in the water as well as raising of the water temperature, which in its turn will lead to breaking of the entire ecosystem of Sevan", - Danielyan said.
"Fluctuation of the water level is fateful. We shall have sharp worsening of the water quality because of the negative balance", - she added.
