 The Kura then empties into Mingachevir reservoir, the largest body of water in Azerbaijan, formed by a dam near its namesake town at the southeastern end.The Iori (also known as Qabirri) and Alazani rivers formerly joined the Kura, but their mouths are now submerged under the lake.After leaving the dam the river meanders southeast where it meets its biggest tributary Tartarchay in Barda rayon and continues across a broad irrigated plain for several hundred kilometers, turning east near Lake Sarysu, and shortly after, receives the Aras, the largest tributary, at the city of Sabirabad.
