Site description This IBA includes a reservoir (max. depth 79 m), temporary wetlands at its inflows and cliff-faces to the north. It lies between Hamam Daðý (site 046) to the south and the Kapýkýrý mountains to the north. The reservoir is fed by three rivers and is used to produce hydroelectric power. Populus and Salix plantations border the seasonal wetlands.

Key Biodiversity This site is important for tree- and cliff-nesting waterbirds and raptors. Large numbers of Ciconia ciconia roost here on migration. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (frequently observed, thought to breed in the surrounds).
