If Lake Sevan Level Decrease Continues, We May Lose Sevan: Experts beating Alarm Singal

If the decrease in Lake Sevan level has a continuous nature, we won't have Lake Sevan after several years, as the experts of the Scientific Center for Zoology and Hydroecology of NAS RA said in their interview with EcoLur. In 2017, 270 million cum water was taken out of Lake Sevan, which was more by 100 million cum than the statutory limit. Despite the official claims that additional water outlet won't lead to a negative balance, Lake Sevan had its negative balance. In the recent decade, additional water intake was carried out from Lake Sevan in 2008, 2012, 2014 and 2017. Besides 2017, a negative balance was recorded also in 2012 and 2014. 'If the lake level goes down by several centimeters within one year, it won't impact the lake immediately, but if the decrease continues, we will have a worse situation than we used to have. Even a decrease in centimeters shouldn't turn into a standard, it should occur only in extreme cases.' If this continues for several years, we will have both water deterioration and a decrease in fish reserves. Now shore washing process is in progress and washed organic and biological materials have decreased. If there is no water amount increase, we will have more concentration in the same volume,' the Director of the Scientific Center for Zoology and Hydroecology of NAS RA Bardukh Gabrielyan said. 'I'm concerned with the fact that the precipitation was too low this year and if Sevan water was used in high-precipitation years, I have concerns they will seek to use it even this year, which means a new decrease in the level. The decrease in each centimeter of Lake Sevan level contains 12.5 million cum water. We should fight to preserve these water resources. If we start spending Sevan water at these rates, we won't have Sevan after several years,' Director of Hydroecology and Ichthyology Director of NAS RA Evelina Ghukasyan said. As of 19 January 2018, the level of Lake Sevan makes up 1900.42 cm, which is lower by 3 cm than the indicator for the same year last year. From its highest peak in 2017, 1900.91 cm, Lake Sevan level has decreased by 49 cm so far.
