Nahuel Huapi Lake
Nahuel Huapi Lake (Spanish: Lago Nahuel Huapi) is an Andean lake in the lake region of northern Patagonia between the provinces of Río Negro and Neuquén, in Argentina. The lake has a northwest-southeast elongated shape and complex geography with several branches, peninsulas and islands. The city of Bariloche is on the southern shore of the lake and the town of Villa La Angostura lies on its northwestern shores. The lake is wholly inside Nahuel Huapi National Park. It is one of the largest lakes in northern Patagonia. It is drained by Limay River and it is part of the watershed of Negro River which discharges into the South Atlantic.
The name of the lake derives from the toponym of its major island in Mapudungun (Mapuche language): "Island of Puma", from nahuel, 'puma', and huapí, 'island'. There is, however, more to the word "Nahuel"—it can also signify 'a man who by sorcery has been transformed to a puma'.
Nahuel Huapi lake, located within the Nahuel Huapi National Park, has a surface of 530 km2 (200 sq mi), rests 770 metres (2,510 ft) above the sea level, and has a maximum measured depth (as of 2007) of 464 metres (1,522 ft).
Its seven branches are named Blest (36 km2 or 14 sq mi), Huemul (21.5 km2 or 8.3 sq mi), de la Tristeza (18.5 km2 or 7.1 sq mi), Campanario (7.9 km2 or 3.1 sq mi), Machete, del Rincón and Última Esperanza. It is connected to other smaller lakes such as Gutiérrez, Moreno, Espejo and Correntoso. The deep-blue waters hold a number of islands, most notably Isla Victoria with an area of 31 km2 (12 sq mi), and Isla Huemul on the south end of the lake.
The lake's crystal clear waters are very susceptible to climate changes and have an average surface temperature of 7 °C (45 °F); this makes it both beautiful and treacherous. Hypothermia is one of the risks bathers must undertake. Kayaking is a popular sport on this and adjacent lakes. The lake is also the starting point of the Limay River.
The lake depression consists of several glacial valleys carved out along faults and Miocene valleys that were later dammed by moraines. During the Last Glacial Maximum of the Llanquihue glaciation the lake basin was wholly occupied by a glacier.
The lake has usually a blue colour but on occasion its water have turned turquoise or green after earthquakes in southern Chile such as the one on May 22, 1960 and the one on January 2, 2011.
The June 2011 eruption of the Puyehue-Cordón Caulle volcanic complex, in neighboring Chile, caused parts of the lake's surface to be blanketed in volcanic ash.
