Lake Geneva
Template:Short description Template:Other uses Template:Expand French Template:Use dmy dates Template:Use British English Template:Infobox lake
Lake GenevaTemplate:Notetag is a deep lake on the north side of the Alps, shared between Switzerland and France. It is one of the largest lakes in Western Europe and the largest on the course of the Rhône. Sixty percent (Template:Cvt) of the lake belongs to Switzerland (the cantons of Vaud, Geneva and Valais) and forty percent (Template:Cvt) to France (the department of Haute-Savoie).
Name
[edit]While the exact origins of the name are unknown, the name Template:Lang was in use during the time of Julius Caesar.<ref name="name-LeNews">Template:Cite web</ref> Template:Lang comes from Ancient Greek Template:Lang (Template:Lang) meaning "port's lake".Template:Citation needed In Medieval Latin it was known as Template:Lang, although this name was also used for a town or district on the lake, or Template:Lang; the equivalent in Old French was Template:Lang.Template:Citation needed Following the rise of Geneva it became Template:Lang<ref>Template:Cite book</ref> (translated into English as Lake Geneva), but Template:Lang was the common name on all local maps<ref>Template:Cite web</ref><ref>Template:Cite web</ref> and is the customary name in the French language. In contemporary English, the name Lake Geneva has become predominant.<ref name="name-LeNews"/>
Geography
[edit]Lake Geneva is divided into three parts because of its different types of formation (tectonic folding, glacial erosion, sedimentation):<ref name="NationalMap200-03"/>
- Template:Lang (Template:Gloss), the eastern part from the Rhône estuary to the line of Meillerie–Rivaz
- Template:Lang (Template:Gloss), the largest and deepest basin with the lake's largest width
- Template:Lang (Template:Gloss), the most south-west, narrower, and less-deep part from Yvoire–Promenthoux next Prangins to the exit in Geneva
According to the Swiss Federal Office of Topography, Swisstopo, Template:Lang designates that part of the Template:Lang which lies within the cantonal borders of Geneva (excluding the cantonal exclave Céligny), so about from Versoix–Hermance to the Rhône outflow in Geneva.<ref name="NationalMap50-270">Template:Cite web</ref>
The Chablais Alps border is its southern shore, and the western Bernese Alps lie over its eastern side. The high summits of Grand Combin and Mont Blanc are visible from some places.
The lake lies on the course of the Rhône. The river has its source at the Rhône Glacier near the Grimsel Pass to the east of the lake and flows down through the canton of Valais, entering the lake between Villeneuve and Le Bouveret, before flowing slowly towards its egress at Geneva. Other tributaries are La Dranse, L'Aubonne, La Morges, La Venoge, La Vuachère, and La Veveyse.
Lake Geneva is the largest body of water in Switzerland, and greatly exceeds in size all others that are connected with the main valleys of the Alps. It is in the shape of a crescent, with the horns pointing south, the northern shore being Template:Cvt and the southern shore Template:Cvt in length. The crescent form was more regular in a recent geological period, when the lake extended to Bex, about Template:Cvt south of Villeneuve. The detritus of the Rhône has filled up this portion of the bed of the lake, and it appears that within the historical period, the waters extended about Template:Cvt beyond the present eastern margin of the lake. The greatest depth of the lake, in the broad portion between Évian-les-Bains and Lausanne, where it is just Template:Cvt in width, has been measured as Template:Cvt, putting the bottom of the lake at Template:Cvt above sea level. The lake's surface is the lowest point of the cantons of Valais and Vaud.<ref name = Ball>John Ball, A Guide to the Western Alps, p. 254</ref> The culminating point of the lake's drainage basin is Monte Rosa at 4,634 metres above sea level.<ref>Template:Cite map</ref>
The beauty of the shores of the lake and of the sites of many of the places near its banks has long been celebrated. However, it is only from the eastern end of the lake, between Vevey and Villeneuve, that the scenery assumes an Alpine character. On the south side, the mountains of Savoy and Valais are for the most part rugged and sombre, while those of the northern shore fall in gentle vine-covered slopes, thickly set with villages and castles.<ref name=Ball/>
The snowy peaks of the Mont Blanc Massif are shut out from the western end of the lake by the Voirons mountain, and from its eastern end by the bolder summits of the Grammont, Cornettes de Bise, and Dent d'Oche, but are seen from Geneva, and between Nyon and Morges. From Vevey to Bex, where the lake originally extended, the shores are enclosed by comparatively high and bold mountains, and the vista terminates in the grand portal of the defile of St. Maurice, cleft to a depth of nearly Template:Cvt between the opposite peaks of the Dents du Midi and the Dent de Morcles.<ref name = Ball/>
The shore between Nyon and Lausanne is called Template:Lang because it is flatter. Between Lausanne and Vevey it is called Lavaux and is famous for its hilly vineyards.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
The average surface elevation of Template:Cvt above sea level is controlled by the Template:Ill in Geneva.<ref>Seujet / Lac Léman Template:Webarchive rhone-geneve.ch. Retrieved on 20 July 2009</ref>
Climate
[edit]Due to climate change, the average temperature of deep water (more than Template:Convert deep) increased from Template:Convert in 1963 to Template:Convert in 2016 (an increase of Template:Convert in 53 years), while the average temperature of surface water (Template:Convert deep) increased from Template:Convert in 1970 to Template:Convert in 2016 (up Template:Convert in 46 years).<ref>La lettre du Léman, bulletin of the Commission internationale pour la protection des eaux du Léman, number 54, June 2017, page 3.</ref> Template:Weather box
Bise
[edit]Lake Geneva (and particularly the lakeside parts of the city of Geneva) can be affected by the cold Bise, a northeasterly wind. This can lead to severe icing in winter.<ref>Template:Cite news</ref> The strength of the Bise wind can be determined by the difference in air pressure between Geneva and Güttingen in canton of Thurgau. The Bise arises when the air pressure in Güttingen is higher than in Geneva.<ref>Template:Cite web</ref>
Environment
[edit]
In 563, according to the writings of Gregory of Tours and Marius Aventicensis, a tsunami wave swept along the lake, destroying the fort of Tauredunum and other settlements, and causing numerous deaths in Geneva. Simulations indicate that this Tauredunum event was most likely caused by a massive landslide near the Rhône delta, which caused a wave Template:Convert high to reach Geneva within 70 minutes.<ref>Template:Cite journal</ref><ref>Template:Cite news</ref><ref>Template:Cite journal</ref> In 888, the town was part of the new Kingdom of Burgundy, and, with it, was absorbed into the Holy Roman Empire in 1033.
In the late 1960s, pollution made it dangerous to swim at some beaches of the lake; indeed, visibility underwater was near zero.<ref>Template:Cite web</ref><ref>Template:Cite book</ref> By the 1980s, intense environmental pollution (eutrophication) had almost wiped out all the fish. Endemic whitefish species Coregonus fera was last recorded in the lake in 1920 and is now extinct. Although the name fera is still used for the only coregonid present in the lake, this is not the original species but the introduced C. palaea. Today, pollution levels have been dramatically cut back, and it is again considered safe to swim in the lake.<ref>Template:Cite web</ref><ref>Template:Cite journal</ref> Major leisure activities practiced include sailing, wind surfing, boating (including water skiing and wake-boarding), rowing, scuba diving, and bathing.
A total of four submarines have plied the depths of Lake Geneva.<ref name=MIR2011>Template:Cite news</ref> In 1964, Jacques Piccard launched a tourist-oriented submarine, the Auguste Piccard (named for his explorer father), for the Swiss National Exhibition, meant to honor the Expo 64 theme of accomplishments by Swiss engineers and industry.<ref name=Picard>Template:Cite news</ref> After operating through to 1965 in Lake Geneva, Piccard used the vessel for scientific exploration in other parts of the world.<ref name=Picard/> Piccard later built the F.-A. Forel, launched in Lake Geneva in 1978 and used primarily for scientific research until it was retired in 2005.<ref name=Picard/> In 2011, in a collaborative operation led by Template:Lang, two Mir submersibles were used for ten weeks to conduct extensive scientific research in Lake Geneva.<ref name=MIR2011/>
On a scientific footnote, in 1827, Lake Geneva was the site for the first measurement of the speed of sound in (fresh) water.<ref name="Guichonnet">Template:Cite book</ref> French mathematician Jacques Charles François Sturm and Swiss physicist Daniel Collodon used two moored boats, separated by a measured distance, as the transmitting and receiving platforms for the sounds of exploding gunpowder. The loud airborne sound coupled into the lake, establishing a loud underwater sound that could be measured at a distance. The flash of the exploding gunpowder provided the visual starting cue for the timepiece, and the underwater explosion sound striking a bell provided the finish cue.
The lake is rich in wildlife, especially birds: both the common buzzard and the red kite breed here in considerable numbers.
Sport events
[edit]Yacht racing is a popular sport, and high-performance catamarans have been developed specifically for the lake.<ref name=alinghi>Template:Cite web</ref> The design of the Alinghi 5, the defender of the 2010 America's Cup, was influenced by those racing catamarans.<ref name=alinghi/> The best-known event, the Template:Interlanguage link (not to be confused with other events having the same name) runs from Geneva to the end of the lake and back.<ref>Template:Cite web</ref>
The Template:Lang rowing event also takes place on Lake Geneva. Competitors row once around the entire lake, making this Template:Convert event the longest non-stop rowing regatta in the world.
Several competitions for swimmers are organised yearly, the longest of which spans the length of the lake from Chillon Castle to Geneva (70km) and is known as The Signature.<ref>Template:Cite web</ref> Other events include the crossing of the lake from Lausanne to Evian (13km),<ref>Template:Cite web</ref> from Montreux to Clarens (1.8 km),<ref>Template:Cite web</ref> in Geneva (1.8 km),<ref>Template:Cite news</ref> all in summer, and the Template:Lang, 125m in Geneva in December.<ref>Template:Cite news</ref>

[edit]Notable residents
[edit]Edmund Ludlow, famous as one who had signed the death warrant of English King Charles I, was granted on 16 April 1662 protection in and continued to live at Vevey until his death in 1692.<ref>Macaulay, History of England, Vol 1, Page 400, J H Dent 1953.</ref> Mary and Percy Shelley and Lord Byron holidayed by the lake and wrote ghost stories, one of which became the basis for the novel Frankenstein.<ref>Template:Cite book</ref> The Empress Elisabeth of Austria (Sisi) was stabbed to death on the quayside in Geneva in September 1898. Vladimir Lenin rented a little "chalet" at the French bank, near Geneva.<ref>Template:Cite news</ref> Actor Charlie Chaplin spent his final years and died in Vevey (there is a memorial statue of him along the promenade; his home at Corsier-sur-Vevey is now a museum of his life and career). Actors Noël Coward, James Mason, Sir Peter Ustinov, Richard Burton, and Audrey Hepburn all lived in villages on the shores of or in view of the lake. David Bowie moved to a chalet to the north of Lake Geneva in 1976, which inspired him to take up painting and informed the first stages of the "Berlin Trilogy". Pop singer Phil Collins lives in a home overlooking the lake.<ref>Template:Cite newsTemplate:Cbignore</ref> Rock band Queen owned and operated Mountain Recording Studios (which is still in use today) in Montreux, and a statue of lead singer Freddie Mercury, who also owned a second home in Montreux, stands on the northern shore of the lake. Writer Vladimir Nabokov also took residence in Montreux, where he died in 1977. Former Formula 1 driver Michael Schumacher lives with his family in a home overlooking the lake.
