Experts warn that Armenia’s largest lake, Lake Sevan, is facing a serious threat from algae and falling water levels. Earlier this month, Armenia’s government posted satellite images showing important parts of the lake covered in green. The coloring is caused by a significant algae bloom in the lake. The images have raised public concern over one of the largest freshwater high-altitude lakes in the world. Seyran Minasyan, director of the Institute of Chemical Physics of the National Academy of Sciences of Armenia, says the blooming process begun roughly 60 to 70 years ago when water started being used for irrigation and electricity. Lake Sevan is situated in Armenia’s Gegharkunik Province, at an altitude of 1,900 m above sea level. The total surface area of its basin is about 5,000 km2, which makes up one sixth of Armenia's territory. Minasyan says that the declining water levels is one of the threats to the lake, but it’s not the only one.
