YEREVAN, July 22. /ARKA/. The ministry of nature protection of Armenia announced Tuesday the provision of €5 million for restoration and maintenance of the balance of the ecosystem of Lake Sevan. The ministry also provided information on the next “greening” of parts of the lake.

It is reported that the expert subdivisions of the ministry on a daily basis observe the activation of blue-green algae in the lake – in the regions of large and small Sevan and that all necessary measures are being taken.

It is noted that, according to experts, the main reasons for the decrease in the intensive growth of blue-green algae and the drop in water quality in the lake are the high water temperature since winter and the high percentage of phosphorus in the lake.

Due to the unprecedented volume of clearing the coastal forest cover of Sevan, which started in 2019, the concentration of phosphorus in the lake has incomparably decreased this year. During the past year, about 100 hectares of forest cover were cleared on the coastal areas, this year the work will continue.

Along with this, the process of mapping and inventorying buildings and structures to be dismantled, located on the coastal areas of Sevan below the mark of 1901.5 meters, began. Community-owned buildings and structures will be dismantled by using public funds. The owners of private buildings and structures have already been sent appropriate notifications to dismantle their buildings at their own expense.

It is also noted that the document on the lake’s problems was created, which was presented to the partner donor organizations of the EU for financing. For these purposes, about €5 million was allocated.

The following measures were pointed out by the ministry as requiring quick solutions: ban on sewage flow from Gegharkunik region to the lake; implementation of works on cleaning the polluted river beds of the Sevan drainage basin; reclamation of territories occupied by subsoil waste.

Lake Sevan is the main source of drinking water in the region, one of the largest alpine lakes in Europe and Asia, located in the very heart of the Armenian Highlands, at an altitude of 1914 meters. In length, from north-west to south-east, the lake extends for more than 70 kilometers, and the area of its water surface reaches almost 1.5 thousand square kilometers.

The only source from the lake is the Hrazdan River (a tributary of the Araks), while 28 rivers flow into it, the total area of the basins, which is 2776 sq. kilometers. By 2030, the lake level is planned to be increased to the optimal 1903.5 m.
