Site description A natural brackish lagoon (20 m deep) situated west of Ýstanbul on the Sea of Marmara. Fringe vegetation is confined to an area of reedbed (Phragmites) in the north of the lagoon. Unplanned buildings surround the site; the only relatively undisturbed area lies within the grounds of the nuclear energy research centre and military camp on the east shore.

Management considerations The construction of a drinking water reservoir on the Sazlý stream has reduced freshwater inflowthe lagoon may become more saline as a result of seawater intrusion. Urban and industrial pollution is a problem that will intensify with further development of the lake surrounds.
