SEVAN, MAY 8, NOYAN TAPAN. The level of the Sevan Lake rose by 25 sm in April and made 1898.42 metres what is higher by 42 sm compared with the 2005 same month index. As the Noyan Tapan correspondent was informed by the "Hayhidromet" Gegharkunik marz department, the reason of such a great index is the fixed heavy rains and snows and partly overflows of rivers streaming into Sevan. Taking into account, that overflows of rivers streaming into Sevan are expected in May as well as the size of the water moving to the lake from the Arpa-Sevan tunnel, it is supposed that the level of Sevan will significantly rise up to the first half of June. In parallel to rising the level of water in the lake, a problem arose connected with coastal territories and constructions: in consequence of rise of the lake level, they remain under water and start to putrefy. As a result, lack of oxygen is felt in the lake, what has a negative influence on vital activity flora and fauna existing in it.
