Ağgöl (meaning "White Lake" in Azerbaijani) is a large salty lake in Kur-Araz Lowland, Agjabadi and Imishli raions of southeastern part of Azerbaijan. It is the second largest lake of Azerbaijan and one of about 450 lakes of the country.[2] Ağgöl is considered one of the most important habitats in Azerbaijan as well as in Caucasus. Located in Ağgöl National Park, it is a part of the wetland system which is an important location for migrating birds, especially for globally endangered species stopping-over and breeding at Aggöl.[3][4]

Overview
History
Ağgöl is believed to be one of the seven lakes which were created as a result of a major earthquake in Ganja on September 25, 1139, when huge block of Mount Kapazcollapsed blocking the path of rivers thus creating a beautiful lake Göygöl and seven other smaller lakes: Maral-gol, Jeyran-gol, Ordek-gol, Zalugolu, Aggöl, Garagol and Shamligol.[5][6] The further formation of the lake was also due to landslides.[7] Origins of the lake are connected to Araz and Kura rivers as well as rivers originating in Karabakh Plateau. The water flowing in from Araz enriches the lake with chlorides and has high mineralization. It is argued that throughout the ages, the rivers have flooded the area creating depressions and then refilled them with water. Before the 20th century, Ağgöl was already partially fed by drainage waters from irrigated fields. The volume of water in the lake had fluctuated in the past when it faced being dried out in single years and when it reached very high volumes of water in other years. When the Mingachevir dam was built in the mid 20th century, the water regime in the Mil steppe and Kura-Araz lowland changed. From 1960, the water to the lake inflowed only from saline water collectors built in the region to drain irrigation waters. In the present, the lake is fed by "K-2" and "K-3" collectors. Some areas around the lake have been used as pasture grounds. Other areas were transformed into irrigated agricultural lands used to grow cotton, wheat, lucerne, vegetables and wine.[3]
Protected area
The Ağgöl is often described as eutrophic lake. The overall area is about 56.2 km2 (21.7 sq mi) and the volume of water in the lake is 44.7 million m3.[8] The average water depth of 0.8 m, maximum depth being 2.5 m. Water levels tend to be lowest in August. With arrival of fall, the level rises and reaches its maximum during rain season in the spring. There are two islands (10 ha) covered by reed. In 1978, the area of the lake was declared zapovednik thus setting the highest level of protection category allowing only the scientific research. In 2001, the global importance of the lake was internationally recognized when the area was declared as Important Bird Area (IBA) when it was placed in the list of Ramsar wetlands of international importance. Therefore, in 2003, the protected area was enlarged by the presidential decree to the size 18,000 ha (180 km2). It is managed by the Ministry of Ecology and Natural Resources of Azerbaijan Republic.[3] The ministry supervises the activities in preservation of the flora and fauna in the protected area and guards it against illegal hunting and fishing.[9]
Climate
The lake usually does not freeze with a few exceptions due to infrequent severe frost. The total annual precipitation at the lake is up to 332 mm, minimum being 13 mm in August and maximum of 37 mm in March.[3]
Effects of Karabakh conflict
Due to the Nagorno-Karabakh conflict internally displaced persons in Azerbaijan|Azerbaijani refugees and internally displaced persons]] from Karabakh and Armenia were resettled in many regions of Azerbaijan, a large part of which was concentrated in 84 settlements of Agjabadi raion. Some were placed in villages around Aggöl. Due to lack of food, this also caused increase in illegal fishing thus affecting the fauna of the lake.[3]
