Lake Garda

Lake Garda and the mountains above Malcesine.

The northern part of the lake is narrower, surrounded by mountains, the majority of which belong to the Gruppo del Baldo. The shape is typical of a moraine valley, probably having been formed under the action of a Paleolithic glacier. Although traces of the glacier's actions are evident today, in more recent years it has been hypothesised that the glacier occupied a previously existing depression, created by stream erosion 5 to 6 million years ago.

The lake has numerous small islands and five main ones, the largest being Isola del Garda, where, in 1220 St. Francis of Assisi founded a monastery. In its place now stands a 19th century building in the Venetian Gothic style. Nearby to the south is Isola San Biagio, also known as the Isola dei Conigli ("Island of the Rabbits"). Both are offshore of San Felice del Benaco, on the lake's western side. The three other main islands are Isola dell'Olivo, Isola di Sogno, and Isola di Trimelone, all farther north near the eastern side. The main tributary is the Sarca River, others include the Ponale River (fed by Lago di Ledro), the Varone/Magnone River (via the Cascate del Varone) and various streams from both mountainsides, while the only outlet is the Mincio River (79 metres (259 ft), at Peschiera). The subdivision is created by the presence of a fault submerged between Sirmione and Punta San Vigilio which is almost a natural barrier that hampers the homogenization between the water of the two zones.

If the water level of the Adige river is excessive, water is diverted to the lake through the Mori-Torbole tunnel.

Lake Garda from space with its wind pattern

The particularly mild climate favours the growth of some hardy Mediterranean plants, including the olive tree, parasol pine, mediterranean cypress, chinese windmill palm and Canary Island Date Palm. Some hardy Citrus trees, such as hardy lemons and satsuma can also be found, which are extremely rare at this latitude (46° North).[2] This greatly favoured the development of tourism since the end of WWII. In ancient times, poets like Catullus wrote about "Lacus Benacus" with its mild climate vivified by the winds. The lake is oriented from north to south towards the Po Valley, so many winds typical of the lake are the result of a difference between lower and higher altitude temperatures. Due to this, winds are generated that descend from the mountains to the plains in the morning and go back to the mountains in the afternoon. The bottleneck formed by the lake basin affects the timing of the winds, many of which happen on a regular daily basis. The winds are all named, most in regional Italian dialect so a single wind may have different names.

Salmo carpio, also known as the carpione (carpione del Garda[3][4] or Lake Garda carpione[5]) is a rare salmonid fish endemic to Lake Garda. It has been introduced to a number of other lakes in Italy and elsewhere but unsuccessfully in all cases.[3] The population in Lake Garda has been strongly declining, and is considered critically endangered (IUCN 3.1).[4][5] The main threats are due to overfishing, pollution and possibly competition from introduced species such as Coregonus and other Salmonidae.[6]

Adult lake trout outside the mating season are silvery with very few black spots on the body and almost none on the head. During the mating season, some males develop a dark mottled body colouration. Garda lake trout reach a length of up to 50 centimetres. They live primarily in depths of 100 to 200 metres (330 to 660 feet). They feed on zooplankton and bottom-dwelling crustaceans in summer. Males and females reach sexual maturity at two or three years. The mating takes place every one to two years. The spawning takes place in 50 to 300 metres (160 to 980 feet) depth in the vicinity of underwater springs. The maximum age is five years.[7]

• Battle of Lake Benacus, in which Roman forces defeated the Alamanni on the shores of Lake Garda, in the year 268.
• Battle between Milan and Venetian Republic in 1438 following the military engineering feat of galeas per montes.
• Battle of Rivoli, in 1797 during the French campaign of Napoleon I in Italy against Austria.
• Battle of Solferino in 1859, during the Italian Risorgimento. The terrible aftermath of this battle led to the Geneva Convention and the formation of the Red Cross.
• The lake was the site of naval battles in 1866 between Italy and Austria.
• As persuaded by the Nazis, Benito Mussolini established the capital of his Italian Social Republic in late 1943 in a villa in the town of Salò on its shores. It served as a nexus for military operations and communications for German troops who occupied northern Italy in late 1943 during World War II.

According to the Greco-Roman mythology, the River Mincius was the child of the Lake Benacus.[8]

The ancient fortified town of Sirmione, located on the south of the lake, is one particularly popular destination, home to the Virgilio & Catullo Spa Complexes, as well as numerous restaurants, bars, hotels, fashion stores and a market. The picturesque Scaliger castle dates from the 13th century. The Roman poet Catullus had a villa here, and visitors can see a ruined Roman spa named the Grotte di Catullo (Grottoes of Catullus) although there is no evidence linking him to this particular building. The sulfur springs at the tip of the peninsula have a reputation for healing catarrhal conditions, particularly those involving the ear. Another popular town is the town of Garda. Garda is approximately 30 kilometres (19 mi) from the more popular town of Verona. Garda's economy is based on tourism.[9] Nearby, there is Gardaland, one of the most famous theme parks in Italy. At the northern end of the lake, the towns of Riva and Torbole are famous for winds that attract people who sail, windsurf & kiteboard.
