Site description The delta of the Hamzabey and the Sarýçay streams, where they meet the Aegean Sea. The site consists of a 200-ha lagoon, two smaller lakes, reedbeds (Phragmites), Salicornia flats and Tamarix scrub. The lagoon is becoming less saline as a result of freshwater input. Agriculture now occupies most of the delta, and there is a basic fish-trap at the river mouth.

Key Biodiversity The site has lost most of its ornithological importance due to wetland drainage.
