Prespa is the name of two freshwater lakes in southeast Europe, shared by Albania, Greece, and the Republic of Macedonia.
 Of the total surface area, 176.3 km² belongs to the Republic of Macedonia, 46.3 km² to Albania and 36.4 km² to Greece.
 They are the highest tectonic lakes in the Balkans, standing at an elevation of 853 m (2,798 ft).
Salmo peristericus, or the Prespa trout is a variety of trout, a freshwater fish in the Salmonidae family.
 It is endemic to the Lake Prespa watershed at the border area of Greece and the Republic of Macedonia.
Lake Memphremagog (French: "Lac Memphrémagog" ) is a fresh water glacial lake located between Newport, Vermont, United States and Magog, Quebec, Canada.
 The lake spans both Quebec and Vermont, but is mostly in Quebec.
 Most of the watershed that feeds the lake is located in Vermont, and is a source for accumulated phosphorus, sediments and other pollutants.
 Recent cleanup efforts have started to improve the water quality.
 The lake furnishes potable (drinking) water for 200,000 people.
The Cameroon clawless otter ("Aonyx capensis congicus") is a subspecies of the African clawless otter in the family Mustelidae.
 It is found in Cameroon, Republic of the Congo, Democratic Republic of the Congo, Gabon, and possibly Angola, Burundi, Central African Republic, Equatorial Guinea, Nigeria, Rwanda, or Uganda.
 Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, subtropical or tropical swamps, subtropical or tropical moist montane forests, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, freshwater spring, inland deltas, saline lakes, intermittent saline lakes, saline marshes, intermittent saline marshes, shallow seas, subtidal aquatic beds, rocky shores, sandy shores, estuarine waters, intertidal flats, intertidal marshes, coastal saline lagoons, coastal freshwater lagoons, water storage areas, ponds, aquaculture ponds, seasonally flooded agricultural land, and canals and ditches.
 It is threatened by habitat loss.
Mali i Thatë is a mountain in southeast Albania and a part of it being in southwest of Macedonia (known with the name Galičica and declared a National Park) with the highest altitude of 2287 meters.
 It borders Lake Prespa in the east, Lake Ohrid in northwest and overlooks the city of Pogradec to the west.
 It stretches 25 km from north to south and is 8 km wide in its central part.
 Mali i Thatë highest peak is Pllaja e Pusit (meaning "Well's plateau") and it reaches an altitude of 2287 m above sea level.
 It is found within Albania, close to the Macedonian border.
 From this high peak, among several mountains of Albania, both Ohrid Lake and Prespa Lake can be seen as well as the third highest peak in the Republic of Macedonia, Baba Mountain or Pelister Mountain (2601 m).
Peninsula Lake is a lake in Alberta, Canada.
 The lake is located 160 km southeast of the city of Edmonton.
 The salinity of Peninsula Lake causes characteristics such as temperature, nutrient concentrations and plant and animal communities to contrast with those from freshwater lakes.
 The lake is contains high levels of sulphate, sodium and bicarbonate/carbonate concentrations which, are produced by saline groundwater in the region.
 In winter, the temperature of water under the ice drops to 0°C, extremely low, even for Alberta lakes.
 Although the lake contains high mineral levels, plant growth is sparse.
 A few planktonic invertebrates are exceptionally abundant, but there are fewer species than in freshwater lakes.
 There are no fish living in the lake.
The Prespa spirlin, "Alburnoides prespensis", is a fish species of Cyprinidae family.
 Native to the Balcans: Lake Prespa in Greece, Macedonia, and Albania.
 Benthopelagic temperate freshwater fish, up to 9 cm in length.
The Great Lakes (French: "les Grands-Lacs" ), also called the Laurentian Great Lakes and the Great Lakes of North America, are a series of interconnected freshwater lakes located primarily in the upper mid-east region of North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence River.
 Consisting of Lakes Superior, Michigan, Huron (or Michigan–Huron), Erie, and Ontario, they form the largest group of freshwater lakes on Earth by total area, and second largest by total volume containing 21% of the world's surface fresh water by volume.
 The total surface is 94250 sqmi , and the total volume (measured at the low water datum) is 5439 cumi .
 Due to their sea-like characteristics (rolling waves, sustained winds, strong currents, great depths, and distant horizons) the five Great Lakes have also long been referred to as "inland seas".
 Lake Superior is the second largest lake in the world by area, and Lake Michigan is the largest lake that is entirely within one country.
 The southern half of the Great Lakes is bordered by the Great Lakes Megalopolis.
The Lower Prespa dialect (Macedonian: Долнoпреспански дијалект , "Dolnoprespanski dijalekt"), is a member of the western subgroup of the western group of dialects of the Macedonian language.
 This dialect is mainly spoken on the Eastern shore of Prespa Lake and Small Prespa Lake, both in the Republic of Macedonia and by the Slavic-speaking community on the Greek side of the border.
 The Prespa dialect spoken in the Greek community has elements of Greek such as "d/δ".
 This area is mainly composed of villages, such as Brajčino, Dupeni, Štrbovo, Ljubojno, western parts of the Florina regional unit and northern parts of the Kastoria regional unit.
 The Lower Prespa dialect is very similar to the Upper Prespa dialect and Ohrid dialect.
Pllaja e Pusit is a mountain peak located in south-eastern Albania.
 Pllaja e Pusit is 2288 m high being the highest peak of Mali i Thatë.
 Pllaja e Pusit is not only the highest peak of Mali i Thatë but also the highest peak of the mountains separating Lake Ohrid and Lake Prespa.
 To the north - west of Pllaja e Pusit is Lake Ohrid and to the east of this peak is Lake Prespa.
 One of the largest settlements found near the peak is Liqenas.
