The Wörthersee , sometimes also Wörther See ( Slovenian Vrbsko jezero ), is the largest lake in Carinthia and at the same time one of the warmest alpine lakes due to its climatic location.

Geographical and morphometric data

The Wörthersee is 19.39 km² and extends in an east-west direction over 16.5 km. It lies in a depression in the hilly landscape of the Klagenfurt basin , which was largely formed by glaciers during the Ice Age . The sea tub extends from the Velden Bay to Klagenfurt . The catchment area of the Wörthersee covers an area of ​​162.1 km².

The lake is divided into three basins by islands, peninsulas and submarine thresholds. The western basin extends from Velden to Pörtschach , the middle one from Pörtschach to Maria Wörth , and the eastern basin extends from Maria Wörth to Klagenfurt . The deepest point of the Wörthersee is 85.2 m, the mean depth is 41.9 m.

The Wörthersee is fed by a large number of smaller streams, the largest of which is the Reifnitzbach with an average water flow of 0.63 m³ / s . The outflow ( Glanfurt / Sattnitz ) in the east of the lake drains the lake via the Glan and Gurk into the Drau .

Due to the sheltered location and the low flooding, the upper layer of water ( epilimnion ), which is up to 8 meters deep, can reach temperatures of over 25 ° C, while the temperatures on the shore rise significantly higher at times. By the end of June the lake had reached over 20 ° C, the cooling below this temperature only takes place in the course of September. The ice setting begins in mid to late January , and the ice breaks in early to mid March. A closed ice cover only forms in extremely cold winters. The last time Lake Wörthersee froze over completely in February 2006 and it was possible to skate on a track of approx. 15 km.


In the middle part of the lake between Maria Wörth and Pörtschach there were originally three islands, of which the island on which the parish and former collegiate church of St. Primus and Felician became the peninsula in the center of Maria Wörth when the water level fell around 1770 , making the previously existing bridge superfluous. The other two are the Capuchin Island near Unterdellach and the Flower Island (formerly Snake Island), which did not get its previous name from the snakes that lived there, but because of its shape, but was renamed more hospitable to the "Flower Island" a few years ago as part of the Pörtschach lido .

Naming and spelling

The name Wörthersee is mentioned in a document in 1143 as Werdse . The name is based on the name of the village Maria Wörth , first mentioned in a document 875-83 as Uueride . The eponymous place is located on a peninsula (at higher water levels it used to be an island) and was named with the old word Werd (Old High German weride ), island, peninsula; Uferland '(compare the Slovenian name for the village Otok , i.e.' island 'and the numerous German place names with Wörth ). It used to have other names, including Klagenfurter and Veldener See . The latter also reflects the Slovenian name Vrbsko jezero ( Vrba = Velden ).

Legend of the creation of the Wörthersee

Wörthersee-Mandl in bronze, in Klagenfurt
( Heinz Goll , 1962)

A legend tells of a town with splendid houses that is said to have existed hundreds of years ago where the Wörthersee is today. Its inhabitants had become exuberant and exuberant through their wealth, and so it came about that they once gathered for dancing and feasting on the eve of Easter. The ringing of bells indicated the hour was late, but nobody cared about it. Then the door of the ballroom opened and a small, ice-gray man stepped in and looked in amazement at the noisy company. It raised its voice with a grudge: “Oh, you revelers, don't you know what celebration we're celebrating tomorrow? Return home before the hour of penance runs out and punishment reaches you! ”But only scornful laughter answered him, and the couples whirled in the dance even more wildly. A few minutes before midnight the old man entered the room for the second time, from which the drunken screams could be heard. He held a keg in his arm. Once again he urged repentance and repentance: "Otherwise I will open the tap of the keg and death and destruction will come upon you!" Again only raw laughter answers him.

It strikes midnight, all the lights go out, the walls tremble, rain falls and a terrible thunderstorm breaks out. The keg of the missing warner lies with the tap open, endless floods flow from him. They invade every room and flow away until they have inundated the whole city and region and drowned their wicked inhabitants. This is how the Wörthersee was created. Cities, churches and villages are buried in its unfathomable depths, huge fish and water snakes live in the old palaces. When the fishermen drive past the Black Wall on quiet summer evenings, it can happen that they hear a clang and ringing that seems to come from the depths of the lake.

A bronze fountain with the Wörthersee Mandl - including the barrel - in the Kramergasse in Klagenfurt (see picture) commemorates this legend .

Places by the lake

The historic city center of Klagenfurt is about four kilometers east of Lake Wörthersee. It is connected to the lake by the Lend Canal, which was created in the 16th century to transport building materials and feed the moat around the city wall. Klagenfurt includes the Europapark Klagenfurt on the lake and the Maria Loretto peninsula with Maria-Loretto Castle .

The climatic health resort of Pörtschach has a waterfront promenade in the central part of the striking peninsula , which is embellished by a sea of ​​flowers in the summer months.

The second largest town on Lake Wörthersee, Velden, is located at the opposite, western end of the lake. In the more recent past, Velden became known to a broad public as the location of the television series Ein Schloß am Wörthersee , for which three seasons with a total of 36 episodes were filmed and broadcast there between 1990 and 1993.

Turn of the century sea villas

The large number of villas and the very representative bathing and boathouse architecture from this period is also known as Wörthersee architecture and was mainly planned by Viennese architects. The most important representative in this group was Franz Baumgartner . Another important planner was Josef Viktor Fuchs with the Villa Venezia in Pörtschach.


Water quality

The Wörthersee belongs to the meromictic circulation type , which means that the water volume of 816 million cubic meters is not completely mixed, but only mixed up to a depth of 50 to 60 meters, the water body below stagnates. In addition to the factors already mentioned, the low flooding and the sheltered location are the reasons for the relatively deep basin of the lake in relation to the area. Due to this circulation behavior, the deep water is naturally not supplied with oxygen; in addition, dead and sunken organisms cause additional oxygen loss in the depths.

Settlement in the catchment area , which grew rapidly, particularly in the 1960s, caused increased nutrient pollution through the discharge of sewage and thus triggered an upward expansion of the oxygen-free zone. The result was strong eutrophication , which was accompanied by massive algal blooms .

The construction of a sewer network and other renovation measures have ensured that the eutrophication phenomena, which reached a high point in the early 1970s, were quickly contained. Between 1971 and 2002, the Wörthersee developed from a mesotrophic to a weakly mesotrophic body of water with the oligotrophic character of the epilimnion .

Water color

A specialty is the predominance of the Burgundy blood algae (Planktothrix rubescens ) in the plant plankton . This type of algae, one of the blue algae, is distributed throughout the water body between 0 and 30 meters deep in spring and binds the nutrients in the surface layer. As the temperature increases, this alga retreats to a depth of 8 to 20 meters. Therefore, the surface area is relatively low in nutrients and algae during the summer months, a fact that is partly responsible for the excellent optical quality of the surface layer of the Wörthersee.

On hot days, a whitish cloud is noticeable, which gives the Wörthersee its characteristic turquoise color. The lime particles are created by the activity of algae and underwater plants ( assimilation ), which precipitate calcium carbonate from lime-rich water . The lime platelets are deposited in the bank regions and form the light gray lake chalk banks. 

Landscape and nature reserves

Particularly valuable areas in the catchment area of ​​the Wörthersee have been declared landscape (LSG) and nature conservation areas (NSG):

  • LSG Maiernigg: 24 ha, LGBl. No. 69/1970
  • LSG Lendspitz - Siebenhügel: 104 ha, LGBl. No. 67/1970
  • LSG Pyramidenkogel: 770 ha, LGBl. No. 73/1970
  • LSG Rauth: 152 ha, LGBl. No. 72/1970
  • LSG Schrottkogel: 504 ha, LGBl. No. 71/1970
  • LSG Villa Alban Berg: 12 ha, LGBl. No. 92/1971
  • NSG Walterskirchen: 23 ha, LGBl. No. 37/1953
  • LSG Pörtschacher peninsula: 8 ha, LGBl. No. 76/1970
  • LSG Leonstain: 22 ha, LGBl. No. 75/1970

Fish stocks

The following fish species are native to the Wörthersee:

The most common fish in the Wörthersee are the pike and the Reinanke.


Ornithological following species can be observed: coot , common loon , swan , gray heron , great crested grebes , mute swan , teal , black-headed gull , mandarin duck , tufted duck , the bittern , mallard , moorhen and little grebe .

Some migratory birds use the Wörthersee as winter quarters.

Not least because of its location between the two largest cities in the state, Klagenfurt and Villach , the Wörthersee was opened up for tourism relatively early on. After Klagenfurt was connected to the Austrian railway network by the southern railway in 1864 and the route was then extended along the banks of the Wörthersee to Villach, many wealthy Viennese discovered the Wörthersee as a "summer resort" region. Due to their favorable traffic situation, the towns on the north bank, in particular Velden and Pörtschach , initially benefited from this, while the south bank was little affected by tourism until the end of the 19th century. The reason for this was, on the one hand, the location remote from the railroad; on the other hand, there was no continuous road connection along the southern bank for a long time; the 19 km long Kaiser-Franz-Joseph-Straße (today: Wörthersee-Süduferstraße , L96) was inaugurated in 1899 .

At the end of the 19th century, the Viennese porcelain manufacturer Ernst Wahliss was a major pioneer in the development of tourism . He had the Park Hotel and a villa complex built on the Pörtschach peninsula. In 1890 he bought Velden Castle and turned it into an exclusive hotel complex. The castle is still considered the most famous tourist company on the lake, including its use as a location for films and television productions. It gave its name to the TV series Ein Schloß am Wörthersee with Roy Black and Uschi Glas in the leading roles, which was produced from 1990 to 1992 and which was broadcast in more than 40 countries.

The Wörthersee developed into a meeting place for patrons and artists at the end of the 19th century . Gustav Mahler , for example, created more than half of his symphonies on “summer vacation” in Carinthia, Alban Berg spent his decisive compositional years in Auen near Velden and Johannes Brahms vacationed in Pörtschach in the summer months from 1877 to 1879. Today you can follow Brahms's footsteps along a 6 km long themed hiking trail near Pörtschach. His composing house, which has been converted into a museum, near the Maiernigg lido near Klagenfurt, is reminiscent of Mahler.

In the interwar period, international celebrities met in Castle Windisch-Graetz in Sekirn on the south bank, where the villa of the billionaire Heidi Horten now stands. Eduard , the Duke of Windsor, and his wife Wallis Simpson were guests there as well as the future US President John F. Kennedy , who in August 1939, a 22-year-old student, spent the last days before the outbreak of the Second World War in the castle. Prominent regulars at Lake Wörthersee in the second half of the 20th century included Heinz Conrads and Peter Alexander , who owned a villa in Krumpendorf.

“See and be seen” is still popular with tourists, especially in the summer season. The Wörthersee is a lifestyle destination due to some modern leading companies, the comparatively high density of gourmet restaurants and events known throughout Austria such as Fête Blanche, Pink Lake or Starnacht . To extend the season, the region is also increasingly positioning itself as an adventure space for hikers and athletes. In addition to numerous other themed hiking trails, the 55-kilometer-long Wörthersee circular hiking trail plays a central role.

The most popular excursion destination on Lake Wörthersee since the redesign in 2013 has been the all-year-round viewing tower on the Pyramidenkogel , which is visited by more than 300,000 people every year.

In 2018, the Wörthersee tourist region (excluding Klagenfurt) recorded around 1.6 million overnight stays with 465,000 arrivals. Most of the vacationers came from Austria, Germany and the Benelux countries.

Klagenfurt shipyard
Steamship Thalia
Motor ship Carinthia

In the spring of 1853 Baron Edmund von Herbert founded the first steamship company on Lake Wörthersee and invested 13,500 guilders for a used paddle steamer, the Maria Wörth , which remained the only ship in his steamship company.

Line operations began on October 9 of the same year, and the Maria Wörth drove twice a day from Velden to Klagenfurt and back again. First class passengers had to pay 1 gulden, a seat in second class cost 36 cruisers. At that time, this shipping line was purely a transport connection that was used by the residents to go shopping or to work, mainly to Klagenfurt. At that time it was possible to take the Maria Wörth on the Lend Canal to the "Lendhafen" in the center of Klagenfurt. More than 30,000 passengers were transported by the Herbert'schen Dampfschifffahrtsgesellschaft in the first year, even though the fare was very high.

In 1863 the southern railway line was extended so that Klagenfurt could also be reached by train. As a result, tourism increased on Lake Wörthersee, and steamboat trips became very popular with holidaymakers. The work on a steamship was tough, as the coal used to power the steamships had to be refilled by stokers with shovels. They had to work up to 350 hours a month, but were paid accordingly. The steamers had to start heating about two hours before departure so that enough steam was available for sailing.

In 1883, 175,000 passengers were carried every year. By 1930 the number of passengers rose to 230,000. From 1891, the people of Klagenfurt had access to a horse-drawn tramway along the Lend Canal in addition to the Lend Canal shipping. Their destination was the ship landing stage on Lake Wörthersee near Klagenfurt, where the large steamships left. The first bus line was also no serious competition for the two shipping companies.

The largest ships on the lake were the Thalia (1909), the Helios (1892), which was called Pörtschach for a decade from 1928 , and the Neptun (1883), all of which continued to sail the Wörthersee as steamships until after the Second World War the old Carinthia had been converted into a motor ship Koschat II . The only ship that remains from this period is the screw steamer Thalia . It too was to be scrapped in the 1980s after 76 years of service. However, this could be prevented, the ship was completely refurbished and brought back into running order. At the beginning of June 1988, the first test drive since the restoration was made. The second maiden voyage took place on July 2nd.

A total of seven shipping companies have shipped to the Wörthersee over the years, some of them relying only on motor ships. In 1913 the last still existing private steamship company was bought up by the city of Klagenfurt and placed under the control of the Klagenfurt municipal utilities, which operated the regular service until 2010; At the end of 2010, shipping was privatized by the city of Klagenfurt and sold to the entrepreneur Martin Ramusch. The purchase included all motor ships, the Thalia steamship and the shipyard facilities. In 2011 the fleet consists of the steamship Thalia , the motor ships Klagenfurt , Carinthia and Velden . In 2012 the electrically powered ship Maria Wörth was added. The latter is mainly used for traffic on the Lend Canal.

The Lorelei and her sister ship the Loretto are among the oldest motor ships . They were launched at the Donauwerft in Vienna in 1924. After 71 years of use as excursion boats, they were finally sold to a private person on the Danube in 1995. When they were eventually to be scrapped in a wreck, the private nostalgia shipping company Wörthersee bought the two historic ships back. The Lorelei and the Loretto came back to the Wörthersee in 1999 and 2001 respectively, have been restored, have been making special trips since 2000 and 2004 and can now each hold 40 passengers. The Nostalgiebahnen in Carinthia association owns and operates both ships.

In 1982 the shipyard in the east bay of the Wörthersee was put into operation and the shipyard is still there today.

Wörtherseeschifffahrt was spared major accidents with one exception: the only accident occurred in 1945 when the engineer was killed in a ship explosion. Instead of a compressed air cylinder, he had connected an oxygen cylinder to start the machine , which led to a violent explosion.

The Wörthersee as a film set

Velden Castle

The Wörthersee has repeatedly served as a location for cinema and television films. The producer Karl Spiehs in particular repeatedly chose the area as a film set for his productions.
Films that take place at Lake Wörthersee:


  • In 1945 the abovementioned explosion of the machine happened on a ship of the Wörtherseeschifffahrt, which killed the machinist.
  • From January 30, 2018, the remains of a 73-year-old rubber dinghy paddler who had been killed in an accident 53 years earlier in 1964 were found at Maria Loretto, Klagenfurt, at a depth of 9.5 m.
  • Compensation proceedings resulted in an accident on June 12, 1977, in which the Klagenfurt motor ship of the Klagenfurt municipal utilities, when the captain stopped trying to land a motor ship at the Pörtschach / Werzer jetty, damaged the ship and caused it to collide. Shortly before, a motorboat that was pulling a water skier had passed between the bridge and the ship, which is why the skipper would have changed the steering.
  • On June 2, 2017, in a motorboat accident while cornering sharply in front of Maria Wörth, a 44-year-old was found dead on the ground the following day with his head injured by the propeller. The 44-year-old boat operator was found guilty of grossly negligent homicide at the Klagenfurt Regional Court in May 2018 and sentenced to ten months of unconditional imprisonment. At the appeal hearing in July 2019, the Graz Higher Regional Court upheld the judgment, but reduced the sentence from ten to nine and a half months of unconditional imprisonment due to the length of the proceedings.
  • Before July 18, 2017, a 21-year-old motorboat driver ran over a 52-year-old swimmer while trying to get the boat to safety from a storm in heavy waves. Despite a severe thigh injury, the swimmer managed to swim back around 15 meters to the jetty on his own.


  • Wörtherseemandl - figure of the legend about the creation of the lake; Fountain figure in Kramergasse, Klagenfurt
  • Hotel Wörthersee - building from 1897 on the western edge of Klagenfurt, between the railway and the road, from 1897, listed, vacant. November 2016 a Polish investor, the owner, represented by his architect Kamil Chmielewski, presented plans for an apartment hotel with a public restaurant; The need for noise protection from railways and motorways and a bathing ban on the bank at the shipyard are mentioned.

Ropeway projects

In October 2016, a development company made up of four hoteliers and shipping entrepreneur Martin Ramusch announced a feasibility study for a cable car from Pörtschach in the north to the south bank of the lake or up to the Pyramidenkogel. Karl Dovjak (SPÖ), Mayor of the Pyramidenkogel community of Keutschach, thought the idea was interesting from a touristic point of view; the first plans for a cable car over Lake Wörthersee had already been made in the 1940s. Nature and landscape conservationists were critical. The then Environment Councilor Rolf Holub (Greens) considered an environmental impact assessment to be necessary and wanted the affected population to vote. For the cable car from a newly designed pool in Pörtschach with a 2.2 km long route - across the lake and 381 meters in altitude on the Pyramidenkogel - costs of around 20 million euros were named in November 2016. Together with a Carinthian park on the Pyramidenkogel, including downhill routes to the south bank, a solar ship across the lake and a covered shopping and fun mile in Pörtschach, 58 million euros were previously rumored in November 2016. Since 2017, the preparations for the implementation of the plans, for which the operators did not want to claim funding, have been on hold. Ramusch named the reason for this in a 2019 interview, the lack of political support.

Resident protests prevented the construction of a cable car from the Wörthersee Stadium to the lakeshore, which was planned by then Governor Jörg Haider for the European Football Championship in 2008 .
