The Burgas Lakes

The Burgas Lakes (Bulgarian: Бургаски езера, Burgaski ezera) or Burgas Wetlands (Бургаски влажни зони, Burgaski vlazhni zoni) are a group of coastal lakes of varying saltiness located around the Bulgarian city of Burgas in the proximity of the Black Sea. They constitute the largest group of lakes in the country and comprise some of Bulgaria's biggest and most important lakes.
The lakes' total area (including swamps, marshes, ponds and other reservoirs) amounts to 95 km², of which 33.30 km² are either proclaimed or proposed protected areas that are inhabited by a large number of locally or globally endangered species of birds, fish and mammals. Apart from this, the Burgas Lakes are also of economic importance, used to obtain sea salt and curative mud, as well as to supply the local economy with fresh water, in the case of Lake Mandrensko.
