34-725: Both branches of the Theodul Glacier are part of the Rhone basin, through the rivers Gornera , Mattervispa , and Vispa . Slightly above the glacier splitting is the Theodul Pass , crossing the border between Switzerland and Italy, and connecting Zermatt to Breuil-Cervinia . On the west, the Theodul Glacier is overlooked by the Matterhorn . Until about 1980s the Lower Theodul Glacier was still connected to

68-463: A 149 km (93 mi) section of the Rhône was made navigable for small ships up to Seyssel . As of 2017 , the part between Lyon and Sault-Brénaz is closed for navigation. The Saône, which is also canalized, connects the Rhône ports to the cities of Villefranche-sur-Saône , Mâcon and Chalon-sur-Saône . Smaller vessels (up to CEMT class I ) can travel further northwest, north and northeast via

102-498: A huge toothed "claw"wheel 6.5 metres (21 ft) across to grip the river bed in the shallows to supplement the paddle wheels. In the 20th century, powerful motor barges propelled by diesel engines were introduced, carrying 1,500 tonnes (3,300,000 lb). In 1933, the Compagnie Nationale du Rhône (CNR) was established to improve navigation and generate electricity, also to develop irrigated agriculture and to protect

136-597: A series of dams and diversion canals, with a navigation lock beside the hydroelectric power plant on each of these canals. The locks were up to 23 metres (75 ft) deep. After building the Génissiat dam on the Upper Rhône (with no lock) in 1948, designed to meet the electricity needs of Paris, twelve hydroelectric plants and locks were built between 1964 and 1980. With a total head of 162 m (531 ft), they produce 13 GWh of electricity annually, or 16% of

170-583: Is 251 cubic metres per second (8,900 cu ft/s). Below the dam, the Rhône receives the waters of the Arve , fed by the Mont Blanc massif, with a visibly higher sediment load and much lower temperature. After a total of 290 kilometres (180 mi) in Switzerland, the Rhône continues west, entering France and the southern Jura Mountains . It turns toward the south, past Lac de Bourget , which

204-718: Is the Plateau Rosa , whose name derives from the Valdôtain patois term Rouése , meaning "ice" (as for the nearby Monte Rosa ). This area lies between Testa Grigia ( French : Tête grise ) (3,479 metres (11,414 ft)) and the Klein Matterhorn, south of and slightly above the Theodul Pass . Southeast of Testa Grigia is a saddle named Passo di Ventina Nord (3,445 metres (11,302 ft)). This area can also be easily accessed by several cable cars connecting Breuil-Cervinia to Testa Grigia. Several lakes formed in

238-875: The Centre -Loire-Briare and Loing Canals to the Seine , via the Canal de la Marne à la Saône (recently often called the " Canal entre Champagne et Bourgogne ") to the Marne , via the Canal des Vosges (formerly called the "Canal de l'Est – Branche Sud") to the Moselle and via the Canal du Rhône au Rhin to the Rhine . The Rhône is infamous for its strong current when the river carries large quantities of water: current speeds up to 10 km/h (6.2 mph) are sometimes reached, particularly in

272-755: The Gorner Glacier and one of its tributaries. The upper section of the Theodul Glacier consists of a flat plateau at around 3,800 metres (12,500 ft), named Breithorn Plateau . The plateau lies between the Breithorn, the Gobba di Rollin and the Klein Matterhorn . The Breithorn Pass (3,814 metres (12,513 ft)) separates the Breithorn from the Gobba di Rollin ( French : Bosse de Rollin ). A 3,795 metres (12,451 ft) high saddle lies between

306-857: The Mediterranean Sea ( Gulf of Lion ). At Arles , near its mouth, the river divides into the Great Rhône (French: le Grand Rhône ) and the Little Rhône ( le Petit Rhône ). The resulting delta forms the Camargue region. The river's source is the Rhône Glacier , at the east edge of the Swiss canton of Valais . The glacier is part of the Saint-Gotthard Massif , which gives rise to three other major rivers:

340-1020: The Reuss , Rhine and Ticino . The Rhône is, with the Po and the Nile , one of the three Mediterranean rivers with the largest water discharge . The name Rhône continues the Latin Rhodanus name ( Greek Ῥοδανός Rhodanós ) in Greco-Roman geography . The Gaulish name of the river was * Rodonos or * Rotonos (from a PIE root * ret- "to run, roll" frequently found in river names). Names in other languages include German : Rhone [ˈroːnə] ; Walser : Rotten [ˈrotən] ; Italian : Rodano [ˈrɔːdano] ; Arpitan : Rôno [ˈʁono] ; Occitan : Ròse [ˈrɔze, ˈʀɔze] ; and Romansh : Rodan . The Greco-Roman as well as

374-872: The Swiss Alps , at an altitude of approximately 2,208 metres (7,244 ft). From there it flows southwest through Gletsch and the Goms, the uppermost valley region of the Valais before Brig . In the Brig area, it receives the waters of the Massa from the Aletsch Glacier , the longest glacier of the Alps, and shortly after, it receives the waters of the Vispa , the longest affluent in Valais. After that, it flows onward through

408-569: The 1980s at the bottom of the Upper Theodul Glacier, west of Trockener Steg. The largest, named Theodulgletschersee is 7.76 ha wide and lies at an elevation of 2,851 metres (9,354 ft) above sea level. It is the highest lake over 4 ha in Switzerland and the largest lake in the Matter Valley (the valley of Zermatt). The second-largest, named Furggsee is 2.57 ha wide and lies at 2,874 metres (9,429 ft). Most of

442-659: The Alps. From Lyon, the Rhône flows south, in its large valley between the Alps and the Massif Central . At Arles , the Rhône divides into two major arms forming the Camargue delta , both branches flowing into the Mediterranean Sea, the delta being termed the Rhône Fan. The larger arm is called the "Grand Rhône", the smaller the "Petit Rhône". The average annual discharge at Beaucaire is 1,700 m /s (60,000 cu ft/s). The main tributaries of

476-647: The Furggsattel (3,349 m), north of the Theodul Pass. The highest cable car was built in 1979. The Theodul Glacier has an alpine climate (Koppen: ET) Rhone The Rhône ( / r oʊ n / ROHN , French: [ʁon] ) is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and Southeastern France before discharging into

510-595: The Gobba di Rollin and the Klein Matterhorn. Between the Klein Matterhorn and the Breithorn is a distinct glacier, named Klein Matterhorn Gletscher , which joins the Lower Theodul Glacier at about 3,000 metres (9,800 ft). The Breithorn Plateau area can be easily accessed by several cable cars connecting Zermatt to the Klein Matterhorn and since July 2023 from the Italian Testa Grigia valley station. At around 3,500 metres (11,500 ft)

544-791: The Morge and Hermance, the lake is divided by the two countries along its centreline, with the left bank in France. The remainder of the lake is Swiss, including the entire right (north) bank. Here, the tributaries are the Veveyse , the Venoge , the Aubonne , the Morges , among other smaller rivers. Lake Geneva ends in the city of Geneva , where the lake level is controlled by the Le Seujet dam  [ fr ] . The average discharge from Lake Geneva

578-654: The Rhône are, from source to mouth: The Rhône has been an important highway since the times of the Greeks and Romans . It was the main trade route from the Mediterranean to east-central Gaul . As such, it helped convey Greek cultural influences to the western Hallstatt and the later La Tène cultures. Celtic tribes living near the Rhône included the Seduni , Sequani, Segobriges , Allobroges , Segusiavi , Helvetii , Vocontii and Volcae Arecomici . Navigation

612-624: The Rhône drains via the Canal de Savières . Continuing generally westward, the Rhône then receives the waters of the Valserine , enters the reservoir created by the Génissiat Dam , and is then joined by the Ain . Reaching Lyon , the most populous city on its course, the Rhône receives its biggest tributary, the Saône , with an average flow of 473 m /s (16,700 cu ft/s), compared to

646-602: The Rhône's 600 m /s (21,000 cu ft/s) at this point. From this confluence, the Rhône follows a southward course. Along the Rhône Valley, it is joined on the right (western) bank by the rivers Eyrieux , Ardèche , Cèze , and Gardon coming from the Cévennes mountains ; and on the left bank by the rivers Isère , (with an average discharge of 333 m /s (11,800 cu ft/s)), Drôme , Ouvèze , and Durance (188 m /s (6,600 cu ft/s)) from

680-492: The adjective derived from the river is rhodanien , as in le sillon rhodanien (literally "the furrow of the Rhône"), which is the name of the long, straight Saône and Rhône river valleys, a deep cleft running due south to the Mediterranean and separating the Alps from the Massif Central . Before railroads and highways were developed, the Rhône was an important inland trade and transportation route, connecting

714-443: The cities of Arles , Avignon , Valence , Vienne and Lyon to the Mediterranean ports of Fos-sur-Mer , Marseille and Sète . Travelling down the Rhône by barge would take three weeks. By motorized vessel, the trip now takes only three days. The Rhône is classified as a Class V waterway for the 325 km-long (202-mile) section from the mouth of the Saône at Lyon to the sea at Port-Saint-Louis-du-Rhône . Upstream from Lyon,

748-521: The country's total hydroelectric production (20% if the Upper Rhône schemes are added). There have been significant benefits for agriculture throughout the Rhône valley. With the Lower Rhône project completed, CNR turned its attention to the Haut-Rhône (Upper Rhône), and built four hydropower dams in the 1980s: Sault-Brénaz, Brégnier-Cordon, Belley-Brens and Chautagne. It also drew up plans for

782-639: The glacier is part of the year-round ski area marketed as Matterhorn Glacier Paradise . It is the highest in Europe and largest summer ski area in the world, with 21 kilometres of prepared pistes. The culminating point is on the summit of Gobba di Rollin and the lowest is above Trockener Steg. The Matterhorn Glacier Paradise links the ski areas of Zermatt and Breuil-Cervina. Ski lifts connect Trockener Steg, Theodul Pass, Testa Grigia, Klein Matterhorn and Gobba di Rollin. A chair lift also connects Trockener Steg to

816-461: The high-capacity Rhine-Rhône Waterway, along the route of the existing Canal du Rhône au Rhin , but this project was abandoned in 1997. In the period from 2005 to 2010, navigation locks of small barge dimensions (40 by 6 m) were built to bypass the last two, forming a navigable waterway network with Lake Bourget, through the Canal de Savières . Cities and towns along the Rhône include: Camargue Too Many Requests If you report this error to

850-633: The historical region of Chablais . It then enters Lake Geneva near Le Bouveret , where the water flows west. On the left (south) bank of Lake Geneva, the river Morge joins at the village of Saint-Gingolph , and also marks the French-Swiss border. Westward, the Dranse (unrelated to the Drance) enters the lake with its preserved delta , and then the Hermance marks another French-Swiss border. Between

884-493: The large glaciers of the massifs of Monte Rosa , Dom , and Grand Combin , but also from the steeper slopes of the Bernese Alps to the north, and the Mont Blanc massif to the west. As a result, the Rhône Valley experiences a drier climate than the rest of Switzerland , being sheltered by the three highest ranges of the Alps, making Valais the driest and largest wine region of the country. At Martigny, where it receives

918-672: The reconstructed Gaulish name is masculine, as is French le Rhône . This form survives in the Spanish/Portuguese and Italian namesakes, el/o Ródano and il Rodano , respectively. German has adopted the French name but given it the feminine gender, die Rhone . The original German adoption of the Latin name was also masculine, der Rotten ; it survives only in the Upper Valais ( dialectal Rottu ). In French,

952-508: The riverside towns and land from flooding. Some progress was made in deepening the navigation channel and constructing scouring walls, but World War II brought such work to a halt. In 1942, following the collapse of Vichy France , Italian military forces occupied southeastern France up to the eastern banks of the Rhône, as part of the Italian Fascist regime's expansionist agenda. In 1948, the French government started construction of

986-468: The stretch below the last lock at Vallabrègues and in the relatively narrow first diversion canal south of Lyon. The 12 locks are operated daily from 5:00 a.m. until 9:00 p.m. All operation is centrally controlled from one control centre at Châteauneuf. Commercial barges may navigate during the night hours by authorisation. The Rhône begins as the meltwater of the Rhône Glacier in Valais , in

1020-412: The upper river used barques du Rhône , sailing barges, 30 by 3.5 metres (98 by 11 ft), with a 75-tonne (165,000 lb) capacity. As many as 50 to 80 horses were employed to haul trains of five to seven craft upstream. Goods would be transshipped at Arles into 23-metre (75 ft) sailing barges called allèges d'Arles for the final run down to the Mediterranean. The first experimental steam boat

1054-490: The valley which bears its name and runs initially in a westerly direction about thirty kilometers to Leuk , then southwest about fifty kilometers to Martigny . Down as far as Brig , the Rhône is a torrent; it then becomes a great mountain river running southwest through a glacial valley. Between Brig and Martigny , it collects waters mostly from the valleys of the Pennine Alps to the south, whose rivers originate from

1088-526: The waters of the Drance on its left bank, the Rhône makes a sharp turn towards the north. Heading toward Lake Geneva ( French : Le Léman ), the valley narrows near Saint-Maurice , a feature that has long given the Rhône valley strategic importance for the control of the Alpine passes. The Rhône then marks the boundary between the cantons of Valais (left bank) and Vaud (right bank), separating two parts of

1122-433: Was built at Lyon by Jouffroy d'Abbans in 1783. Regular services were not started until 1829 and they continued until 1952. Steam passenger vessels 80 to 100 metres (260–330 ft) long made up to 20 km/h (11 kn) and could do the downstream run from Lyon to Arles in a day. Cargo was hauled in bateau-anguilles , boats 157 by 6.35 metres (515.1 by 20.8 ft) with paddle wheels amidships, and bateaux crabes ,

1156-404: Was difficult, as the river suffered from fierce currents, shallows, floods in spring and early summer when the ice was melting, and droughts in late summer. Until the 19th century, passengers travelled in coches d'eau (water coaches) drawn by men or horses, or under sail. Most travelled with a painted cross covered with religious symbols as protection against the hazards of the journey. Trade on
