Site description Situated at the head of the Büyük Menderes river south of Akdað (IBA 019), this freshwater lake (max. depth 7 m) is fed by streams and springs. The lake stores irrigation water for the surrounding agricultural plains, and high water-levels mean that marsh vegetation is only present where the Kufi channel deposits silt into the lake. The IBA includes Gökgöl marshes (including a max. 300 ha lake) 3 km east of Iþýklý Gölü.
