What is the largest lake in Azerbaijan, the name of which translated means "yellow lake"?

Sarysu (Azerbaijani: Sarısu meaning "Yellow Lake") is the largest lake of Azerbaijan located in Imishli and Sabirabad raions (districts) of the Kur-Araz Lowland.

Sarysu lake stretches along the Kura River from Imishli Rayon southeast to Sabirabad Rayon reaching a total length of 22 km (14 mi). It is one of the four lakes present in the area. The water in the lake is fresh water. The lake inflows from Lake Ağgöl through a canal which is also replenished by groundwater and rain - and outflows to the Kura River. The outflow to Kura is regulated by a water-releasing station in Muradbəyli.

The river sometimes overflows and floods. In 1976, overflowing of Kura River caused Sarysu to increase in size by 3-5 times. In May 2010, major flooding struck the area. Heavy rains caused the volume level of Kura river to increase by 12 cm and the level of Sarysu by 20 cm. On 24 May 2010, Muradbeyli village, surrounded by Sarysu on the south and Kura River on the north, completely flooded collapsing the dam. Muradbəyli and three other villages Qasımbəyli, Əsgərbəyli, Axtaçı of Sabirabad Rayon as well as Nərimankənd, Musalı, Dəllər and Novruzlu of Saatly Rayon were evacuated.

Sarysu is a primary source for fishing and partially for irrigation.
