	Lake Sevan - Wikipedia, the free encyclopedia
		Lake Sevan ("Սևանա լիճ" in Armenian), named Gegham Sea ("Գեղամա ծով") in ancient times, is the largest lake in Armenia and one of the largest high altitude lakes in the world.
		In 1981, a 49 km tunnel was constructed, diverting water from the Arpa river (from a reservoir near Kechut) to the lake near Artsvanist.
		Sevan trout (Salmo ischchan) was an endemic species of the lake, but it is endangered as some competitors were introduced into the lake, including common whitefish (Coregonus lavaretus) from Lake Ladoga, goldfish (Carrasius auratus), and crayfish (Astacus leptodactylus).

		Lake Sevan was once a reservoir of water fit for drinking, according to physical, chemical, and biological indices.
		But today, as a result of the intensive exploitation of the lake over the years, its ecological system has been disturbed, with falling water level and resultant swamping bringing about qualitative changes, and the state of its native fish life, the most sensitive index of the health of the lake, has changed.
		Four years ago a project to restore Lake Gilli, in the southeast of the Sevan basin, was launched, and it was expected to play a vital role in saving the Sevan eco-system.

	Sevan trout - Wikipedia, the free encyclopedia
		Sevan trout (Salmo ischchan) is an endemic fish species of Lake Sevan in Armenia.
		It is endangered, because various competitors have been introduced into the lake during the Soviet period, including common whitefish (Coregonus lavaretus) from Lake Ladoga, goldfish (Carrasius auratus) and crayfish (Astacus leptodactylus).
		Should the Sevan trout become extinct in its "home" lake, it seems that it will survive in Issyk-Kul lake in Kyrgyzstan where it was introduced during the Soviet era.

		Yet in the 1960's it was evident that the ecological (and economical) consequences of extensive exploitation of the lake water were rather undesirable and it was impossible to continue utilizing the water at the same pace for a long time.
		Decreasing the water-level affected both the ecosystem of the lake, its physical conditions (temperature, transparency) and biological conditions from phytoplankton to fish community.

	Rise of Lake Sevan Could Drain Armenia's Treasury - Armenia Diaspora Conference Official Site
		Lake Sevan, one of the highest altitude lakes in the world, began dwindling in the 1930s under a plan to use its waters for irrigation and hydroelectricity.
		The government stopped using Lake Sevan for energy in 1999 and two years later parliament passed a law decreeing the water should be raised to 1,903 meters (6,243 feet) above sea level, the height at which experts say it will be possible to regulate the temperature and oxygen levels and restore the ecological balance.
		By the time the lake hits its target level, 10 times that amount will be under water, of which 3,130 hectares (7,734 acres) are forest and the rest resorts, private mansions, arable land and 30 kilometers (20 miles) of highways.

		During the period 1933 to 1981 the lake was used to support the agricultural, industrial and energy sectors and its level dropped dramatically.
		The lake system and its ecological balance were greatly disturbed by that process, which reduced the volume of the lake by 42%, with areas round the edges of the lake drying out.
		However, demand for water from Lake Sevan for energy production rose dramatically during the period 1991 - 1995, and this resulted in a 2.2m drop the level of the lake, and further destabilization of physical, chemical and biotic processes, leading to build up of organic residues in the water of the lake.
