Sarysu (Azerbaijani:Sarısu meaning "Yellow Water") is the largest lake ofAzerbaijan located inImishli andSabirabadraions of theKur-Araz Lowland.[1]
Sarysu lake stretches along theKura River fromImishli Rayon southeast toSabirabad Rayon, reaching a total length of 22 km (14 mi). It is one of the four lakes in the area. The water in the lake isfresh water. The lakeinflows fromLake Ağgöl through acanal – and which is also replenished bygroundwater andrain – andoutflows to the Kura River. The outflow to Kura is regulated by a water-releasing station inMuradbəyli.[2]
The lake is separated from the residential areas in the north by a highway, which prevents it from potential pollution. The southern part of the lake has been polluted from waters of onshoreoil production activities in the past.
The shoreline of Sarysu is mainly made up of wetlands and swamps. The overall area is 65.7 km2 (25.4 sq mi).[3] The approximate volume of water in the lake is 60 million m3. The average depth is 1–3 meters, at the shoreline 0.1-0.9 meters. The increases of volume of water is mainly observed in spring and fall seasons. During the winter season, the average ice-covering period is 11 days. The lake is rich withcommon carp andvobla. Favorable conditions at the lake attract 300-350 thousand migrating birds during the winter.Mineralization at Sarysu is high.[2]
The river sometimes overflows and floods. In 1976, the overflowing of the Kura River caused the lake to increase in size by 3–5 times.[2] In May 2010, major flooding struck the area. Heavy rains caused the volume level of the Kura river to increase by 12 cm and the level of lake Sarysu by 20 cm.[4] On 24 May 2010,Muradbeyli village, surrounded by the lake on the south and the Kura River on the north, completely flooded, collapsing the dam.[5] Muradbəyli and three other villagesQasımbəyli,Əsgərbəyli,Axtaçı of Sabirabad Rayon as well asNərimankənd,Musalı,Dəllər andNovruzlu ofSaatly Rayon were evacuated.[6][7][8]
Sarysu is a primary source for fishing and partially for irrigation.[9][10]
