Lake Natron is a salt or alkaline lake located in north Ngorongoro District of Arusha Region in Tanzania at the border with Kenya. It is in the Gregory Rift, which is the eastern branch of the East African Rift. The lake is within the Lake Natron Basin, a Ramsar Site wetland of international significance. It is the only regular breeding area for Africa's lesser flamingoes, although this habitat is not protected and is under threat from planned development projects.
Lake Poopó was a large saline lake in a shallow depression in the Altiplano in Oruro Department, Bolivia, at an altitude of approximately 3,700 m (12,100 ft). Due to the lake's length and width, it made up the eastern half of Oruro, known as a mining region in southwest Bolivia. The permanent part of the lake body covered approximately 1,000 square kilometres (390 sq mi) and it was the second-largest lake in the country. The lake received most of its water from the Desaguadero River, which flows from Lake Titicaca at the north end of the Altiplano. Since the lake lacked any major outlet and had a mean depth of less than 3 m (10 ft), the surface area differed greatly seasonally.
A Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention, also known as "The Convention on Wetlands", an international environmental treaty signed on 2 February 1971 in Ramsar, Iran, under the auspices of UNESCO. It came into force on 21 December 1975, when it was ratified by a sufficient number of nations. It provides for national action and international cooperation regarding the conservation of wetlands, and wise sustainable use of their resources. Ramsar identifies wetlands of international importance, especially those providing waterfowl habitat.
Lake Urmia is an endorheic salt lake in Iran. The lake is located between the provinces of East Azerbaijan and West Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its greatest extent, it was the largest lake in the Middle East. It is the sixth-largest saltwater lake on Earth, with a surface area of approximately 6,000 km2 (2,300 sq mi), a length of 140 km (87 mi), a width of 70 km (43 mi), and a maximum depth of 20 m (66 ft).
A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The salt pans are shallow and expansive, allowing sunlight to penetrate and reach the seawater. Natural salt pans are formed through geologic processes, where evaporating water leaves behind salt deposits. Some salt evaporation ponds are only slightly modified from their natural version, such as the ponds on Great Inagua in the Bahamas, or the ponds in Jasiira, a few kilometres south of Mogadishu, where seawater is trapped and left to evaporate in the sun.
Lake Corangamite, a hypersaline endorheic lake, is located near Colac in the Lakes and Craters region of the Victorian Volcanic Plains of south-west Victoria, Australia. The lake's salinity levels have increased dramatically as the lake level has dropped in recent decades. It is Australia's largest permanent saline lake, covering approximately 230 square kilometres (89 sq mi) with a circumference of 150 kilometres (93 mi). It forms part of the Ramsar-listed Western District Lakes wetland site. The Aboriginal name of the lake is recorded as Kronimite.
Spittal Pond Nature Reserve is the largest wildlife sanctuary in Bermuda, located close to the Atlantic coast of Smith's Parish. Surrounding the third largest pond in Bermuda, Spittal Pond, it covers an area of 60 acres (24 ha). It is one of 13 parks or reserves managed by the Bermuda Department of Conservation Services which protects and conserves environmentally critical areas and habitats. The pond reserve, a wetland site, is one of the seven Ramsar Sites in Bermuda, which was approved on 10 May 1999 for the criteria of its unique characteristics such as its lagoon which is permanently brackish, ecology featuring wet grassland and mangrove forests, seasonal shorebirds, other ver run waterbirds and European eels. It is also home to many types of species mostly including birds.
Bhitarkanika National Park is a 145 km2 (56 sq mi) large national park in northeast Kendrapara district in Odisha in eastern India. It was designated on 16 September 1998 and obtained the status of a Ramsar site on 19 August 2002. The area is also been designated as the second Ramsar site of the State after the Chilika Lake. It is surrounded by Bhitarkanika Wildlife Sanctuary, which spread over 672 km2 (259 sq mi). Gahirmatha Beach and Marine Sanctuary are to the east, separating the swamp region and mangroves from the Bay of Bengal. The national park and wildlife sanctuary is inundated by the rivers Brahmani, Baitarani, Dhamra, and Pathsala. It hosts many mangrove species, and is the second largest mangrove ecosystem in India.
A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration with depth. Below a certain depth, the solution has a uniformly high salt concentration.
Lake Burdur is a large saline lake of tectonic origin, positioned at the frontier between Burdur and Isparta provinces in southwestern Turkey. It has an area of 250 km2 and a maximum depth variously reported at between 50 and 110 m. The water level in the lake fluctuates. Lake Burdur is also an important wetland site for many bird species and is designated a Ramsar site.
Larnaca Salt Lake is a complex network of four salt lakes of different sizes to the west of the city of Larnaca. The largest is lake Aliki, followed by lake Orphani, lake Soros and lake Spiro. They form the second largest salt lake in Cyprus after the Limassol Salt Lake. The total surface area of the lakes adds up to 2.2 km2 and being just off the road leading to Larnaca International Airport, the lake is one of the most distinctive landmarks of the area. It is considered one of the most important wetlands of Cyprus and it has been declared a Ramsar site, Natura 2000 site, Special Protected Area under the Barcelona Convention and an Important Bird Area (IBA). It is surrounded by halophytic scrubland and on its bank lies the Hala Sultan Tekke, one of the holiest of shrines within Ottoman Islam. It houses the tomb of Umm Haram, Muhammad's 'wet-nurse'.
Trustom Pond is a closed lagoon in South Kingstown, Washington County, Rhode Island, United States. It is one of nine coastal lagoons in southern Rhode Island. It has a surface area of 800 acres (320 ha), and is the only undeveloped salt pond in the state. The pond averages 1.3 feet (0.40 m) deep, and has a salinity level of 5 parts per thousand. It is non-tidal, except when breached by storms. The water directly receives about 219,844,022 US gallons (832,200 m3) of precipitation per year, with an estimated 796,215 US gallons (3,014 m3) in daily groundwater flow. No streams flow into the pond, though a nearby stream "captures water that otherwise would have flowed to Trustom Pond".
The Sonny Bono Salton Sea National Wildlife Refuge is located in the Imperial Valley of California, 40 miles (64 km) north of the Mexican border. Situated at the southern end of the Salton Sea, the refuge protects one of the most important nesting sites and stopovers along the Pacific Flyway. Despite its location in the Colorado Desert, a subdivision of the larger Sonoran Desert, the refuge contains marine, freshwater, wetland, and agricultural habitats which provide sanctuary for hundreds of birds and wetland species, including several that have been listed as endangered or sensitive by the U.S. Fish and Wildlife Service.
Reedy Lake, historically also known as Lake Reedy, is a shallow 5.5-square-kilometre (2.1 sq mi) intermittent freshwater lake or swamp on the lower reaches of the Barwon River, on the Bellarine Peninsula southeast of Geelong in the Australian state of Victoria.

The Sečovlje Saltworks is the largest Slovenian salt evaporation pond. Along with the Strunjan Saltworks, they are the northernmost Mediterranean saltworks and one of the few where salt is still produced in a traditional way, as well as a wetland of international importance and a breeding place for waterbirds. They are part of the Piran Saltworks and are located at Parecag in Slovenian Istria, the southwest of the country, at the Adriatic Sea, along the mouth of the Dragonja River near Sečovlje.
The San Francisco Bay Salt Ponds are a roughly 16,500-acre (6,700 ha) part of the San Francisco Bay that have been used as salt evaporation ponds since the California Gold Rush era. Most of the ponds were once wetlands in the cities of Redwood City, Newark, and Hayward, and other parts of the bay.
The Étang de Palo is a coastal lagoon beside the Tyrrhenian Sea in the Haute-Corse department on the French island of Corsica. The lagoon is largely unspoiled and is considered ecologically valuable.
An anchialine system is a landlocked body of water with a subterranean connection to the ocean. Depending on its formation, these systems can exist in one of two primary forms: pools or caves. The primary differentiating characteristics between pools and caves is the availability of light; cave systems are generally aphotic while pools are euphotic. The difference in light availability has a large influence on the biology of a given system. Anchialine systems are a feature of coastal aquifers which are density stratified, with water near the surface being fresh or brackish, and saline water intruding from the coast at depth. Depending on the site, it is sometimes possible to access the deeper saline water directly in the anchialine pool, or sometimes it may be accessible by cave diving.
