Pellegrini Lake
The Pellegrini Lake is an artificial lake located on the Argentinian Patagonia, in the province of Río Negro, near the city of Cinco Saltos, at approximately and 270 m above mean sea level. This reservoir was originally a natural depressed area, possibly excavated by wind erosion, which was later filled with water brought by a derivation channel from the nearby Neuquén River, in order to regulate its flow (since the river had no natural lakes that would fulfill this function). It has mean and maximum depths of 9.4 and 18 m, respectively. It covers an area of 112 km² and has a volume of 1.053×109 m³. The lake is employed for commercial fishing of ''trucha criolla'' (''Percichthys trucha'', a species of temperate perch) and ''pejerrey'' (''Odontesthes microlepidotus'', a neotropical silverside The Neotropical silversides are a family, Atherinopsidae, of fishes in the order Atheriniformes.

Río Negro Province
Río Negro (, ''Black River'') is a province of Argentina, located in northern Patagonia. Neighboring provinces are from the south clockwise Chubut, Neuquén, Mendoza, La Pampa and Buenos Aires. To the east lies the Atlantic Ocean. Its capital is Viedma near the Atlantic outlet of the province's namesake river in the eastern extreme. The largest city is in the Andean foothills Bariloche in the far west. Other important cities include General Roca and Cipolletti. History Ferdinand Magellan was the first European explorer to visit the coasts of the provinces in 1520. Italian priest Nicolás Mascardi founded the Jesuit mission ''Nuestra Señora de Nahuel Huapi'' in 1670 at the shore of the Nahuel Huapi Lake, at the feet of the Andes range. Originally part of the Argentine territory called Patagonia (in 1878 the ''Gobernación de la Patagonia''), in 1884 it was organised into the ''Territorio Nacional del Río Negro'' and General Lorenzo Vintter was appointed as the territor ...

Patagonia
Patagonia () refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south. The Colorado and Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia. The archipelago of Tierra del Fuego is sometimes included as part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.Manuel Enrique Schilling; Richard WalterCarlson; AndrésTassara; Rommulo Vieira Conceição; Gustavo Walter Bertotto; ...

Artificial Lake
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the r ...

Provinces Of Argentina
Argentina is subdivided into twenty-three federated states called provinces ( es, provincias, singular ''provincia'') and one called the autonomous city (''ciudad autónoma'') of Buenos Aires, which is the federal capital of the republic ( es, Capital Federal, links=no) as decided by the National Congress of Argentina, Argentine Congress. The provinces and the capital have their own constitutions, and exist under a federalism, federal system. History During the Argentine War of Independence, War of Independence the main cities and their surrounding countrysides became provinces though the intervention of their Cabildo (council), ''cabildos''. The Anarchy of the Year XX completed this process, shaping the original thirteen provinces. Jujuy Province, Jujuy seceded from Salta Province, Salta in 1834, and the thirteen provinces became fourteen. After seceding for a decade, Buenos Aires Province accepted the 1853 Constitution of Argentina in 1861, and its capital city was made ...

Cinco Saltos
Cinco Saltos is a city in the province of Río Negro, Argentina, located on the eastern side of the valley of the Neuquén River, near the Pellegrini Lake, about from northwest of Neuquén and from Allen. It has 19,819 inhabitants as per the . The name ''Cinco Saltos'' (literally "Five Waterfalls") refers to the five-level steps of the canal that starts upstream at the Ingeniero Ballester Dam and passes by the eastern limit of the city. It is also host city of the annual La Picasa International Film Festival. History The first settlers came to this land in 1914. At first, the layout of the town was made in the northern area of the railroad, but in 1918 floods covered the lots and prevented further building. On 16 September 1925, the Village Development Committee was formed. During the early years, the city did not have health care, only itinerant doctors. By 3 January 1960, the local rural hospital was founded, in presence of the then Governor Edgardo Castello. The city's g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Wind
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have various asp ...

Neuquén River
The Neuquén River () is the second most important river of the province of Neuquén in the Argentine Patagonia, after the Limay River. Rocks of the Neuquén Basin are fossiliferous, and the basin hosts what may become important fields of tight oil and gas. Overview The river begins in the northwest of the province at an elevation of , to be fed by a number of streams through valleys of the lower Andes while advancing diagonally in southeast direction. Among these streams, some of them from draining of small lakes, are the Trocomán, Reñi Leuvü, Agrio and Nahueve. Further down, its main tributaries are the rivers Varvarco, and Agrio, who provides almost a third of the Neuquén flow. Along its way the river receives some sediments from volcanoes Copahue and Domuyo that might sometimes affect the clarity of the otherwise clean waters. After meeting the Agrio, the Neuquén river has no natural lakes that could regulate its flow, which results in sharp raises of level during thaw ...

Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans ( shrimp/ lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms ( starfish/ sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations ( fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. Fishing has been an important part of human culture since hunter-gatherer times, and is one of the few food production activities that have persisted ...
